What Are PPSU Fittings? The Complete Guide to a Superior Polymer

If you're specifying components for a demanding piping system, you've likely encountered the term PPSU fittings. But what exactly are they, and why are they becoming the material of choice for engineers and contractors worldwide?

In short, PPSU (Polyphenylsulfone) fittings are high-performance connectors made from an advanced, super-tough thermoplastic. They are designed for applications where ordinary plastics like PVC or CPVC would fail.

Key Properties of PPSU Fittings: Why They Stand Out

PPSU material is in a class of its own. Here are the critical properties that make PPSU fittings exceptional:

  • Extreme Heat Resistance: PPSU can continuously withstand temperatures up to 180°C (356°F), far exceeding the capabilities of most other thermoplastics. This makes them ideal for hot water lines, steam applications, and high-temperature fluid transfer.

  • Outstanding Strength and Durability: PPSU is renowned for its exceptional impact strength, even at high temperatures. It is a rigid and tough material that resists cracking and mechanical stress, ensuring long-term system integrity.

  • Superb Chemical Resistance: PPSU fittings excel in harsh chemical environments. They resist a wide range of acids, bases, and other aggressive chemicals, making them perfect for industrial and laboratory settings.

  • Hydrolytic Stability: Unlike some polymers, PPSU does not degrade in the presence of water or steam. This property is crucial for plumbing, medical, and food processing applications where long-term contact with water is guaranteed.

  • Safety and Compliance: PPSU is naturally BPA-free and meets stringent international standards for potable water (WRAS, NSF/ANSI 61) and ultra-pure water systems. It is also compliant with FDA regulations for food contact and is widely used in medical and dental devices due to its biocompatibility and ability to withstand repeated sterilization.

Methods for Troubleshooting Progressive Screw Pumps

 

Regarding faults in screw pumps, we at Anhui Shengshi Datang have some effective solutions.

First, ensure that no foreign objects enter the pump body.

If solid debris enters the pump body, it can damage the rubber stator of the progressive screw pump. Therefore, it is crucial to prevent debris from entering the pump chamber. Some systems install a grinder before the pump, while others use a screen or filter to block debris from entering the pump. Screens should be cleaned promptly to prevent clogging.

 

Second, avoid operating the pump without material.

The progressive screw pump absolutely must not run dry. If dry running occurs, the rubber stator can instantly overheat due to dry friction and burn out. Therefore, having a properly functioning grinder and clear screens are essential conditions for the normal operation of the pump. For this reason, some pumps are equipped with a dry-run protection device. When material supply is interrupted, the self-priming capability of the pump creates a vacuum in the chamber, which triggers the vacuum device to stop the pump.

 

Third, maintain a constant outlet pressure.

The progressive screw pump is a positive displacement rotary pump. If the outlet is blocked, the pressure will gradually rise, potentially exceeding the predetermined value. This causes a sharp increase in the motor load, and the load on related transmission components may also exceed design limits. In severe cases, this can lead to motor burnout or broken transmission parts. To prevent pump damage, a bypass relief valve is usually installed at the outlet to stabilize the discharge pressure and ensure normal pump operation.

progressive screw pumps

Fourth, reasonable selection of pump speed.

The flow rate of the progressive screw pump has a linear relationship with its speed. Compared to low-speed pumps, high-speed pumps can increase flow and head, but power consumption increases significantly. High speed accelerates the wear between the rotor and stator, inevitably leading to premature pump failure. Furthermore, the stator and rotor of high-speed pumps are shorter and wear out more easily, thus shortening the pump's service life.

 

Using a gear reducer or variable speed drive to reduce the speed, keeping it within a reasonable range below 300 revolutions per minute, can extend the pump's service life several times compared to high-speed operation.

 

Of course, there are many other maintenance methods for progressive screw pumps, which requires us to be more attentive during daily use. Careful observation will contribute significantly to proper pump maintenance.

 

How should faults in progressive screw pumps be handled? This article will mainly introduce methods for troubleshooting progressive screw pumps.

1. Pump body vibrates violently or produces noise:

A. Causes:​ Pump not installed securely or installed too high; damage to the motor's ball bearings; bent pump shaft or misalignment (non-concentricity or non-parallelism) between the pump shaft and the motor shaft.

B. Solutions:​ Secure the pump properly or lower its installation height; replace the motor's ball bearings; straighten the bent pump shaft or correct the relative position between the pump and the motor.

2. Transmission shaft or motor bearings overheating:

A. Causes:​ Lack of lubricant or bearing failure.

B. Solutions:​ Add lubricant or replace the bearings.

3. Pump fails to deliver water:

Causes:​ Pump body and suction pipe not fully primed with water; dynamic water level below the pump strainer; cracked suction pipe, etc.

 

The sealing surface between the screw and the housing is a spatial curved surface. On this surface, there are non-sealing areas such as ab or de, which form many triangular notches (abc, def) with the screw grooves. These triangular notches form flow channels for the liquid, connecting the groove A of the driving screw to grooves B and C on the driven screw. Grooves B and C, in turn, spiral along their helices to the back side and connect with grooves D and E on the back, respectively. Because the sealing surface where grooves D and E connect with groove F (which belongs to another helix) also has triangular notches similar to a'b'c' on the front side, D, F, and E are also connected. Thus, grooves A-B-C-D-E-A form an "∞"-shaped sealed space (If single-start threads were used, the grooves would simply follow the screw axis and connect the suction and discharge ports, making sealing impossible). It's conceivable that many independent "∞"-shaped sealed spaces are formed along such a screw. The axial length occupied by each sealed space is exactly equal to the lead (t) of the screw. Therefore, to separate the suction and discharge ports, the length of the threaded section of the screw must be at least greater than one lead.

 

9 Essential Safety Points to Understand Before Using High-Temperature Magnetic Drive Pumps

 

High-temperature magnetic drive pumps are compact, aesthetically pleasing, small in size, and feature stable, user-friendly operation with low noise levels. They are widely used in chemical, pharmaceutical, petroleum, electroplating, food, film processing, scientific research institutions, defense industries, and other sectors for pumping acids, alkaline solutions, oils, rare and valuable liquids, toxic liquids, volatile liquids, and in circulating water equipment, as well as for supporting high-speed machinery. They are particularly suitable for liquids that are prone to leakage, evaporation, combustion, or explosion. It is best to choose an explosion-proof motor for such pumps.

Advantages of High-Temperature Magnetic Drive Pumps:

1. No need to install a foot valve or prime the pump.

2. The pump shaft is changed from dynamic sealing to enclosed static sealing, completely avoiding media leakage.

3. No independent lubrication or cooling water is required, reducing energy consumption.

4. Power transmission is changed from coupling drive to synchronous dragging, eliminating contact and friction. This results in low power consumption, high efficiency, and provides damping and vibration reduction, minimizing the impact of motor vibration on the pump and pump cavitation vibration on the motor.

5. In case of overload, the inner and outer magnetic rotors slip relative to each other, protecting the motor and pump.

6. If the driven component of the magnetic drive operates under overload conditions or the rotor jams, the driving and driven components of the magnetic drive will automatically slip, protecting the pump. Under these conditions, the permanent magnets in the magnetic drive will experience eddy current losses and magnetic losses due to the alternating magnetic field of the driving rotor, causing the temperature of the permanent magnets to rise and leading to the failure of the magnetic drive slip.

 

High-temperature magnetic drive pumps

 

Precautions for Using High-Temperature Magnetic Drive Pumps:

1. Prevent Particle Entry

(1) Do not allow ferromagnetic impurities or particles to enter the magnetic drive or the bearing friction pair.

(2) After transporting media prone to crystallization or sedimentation, flush promptly (fill the pump cavity with clean water after stopping the pump, run for 1 minute, then drain completely) to ensure the service life of the sliding bearings.

(3) When pumping media containing solid particles, install a filter at the pump inlet.

 

2. Prevent Demagnetization

(1) The magnetic torque must not be designed too small.

(2) Operate within the specified temperature conditions; strictly avoid exceeding the maximum allowable media temperature. A platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve to monitor the temperature rise in the gap area, enabling an alarm or shutdown if the temperature limit is exceeded.

 

3. Prevent Dry Running

(1) Strictly prohibit dry running (operating without liquid).

(2) Strictly avoid running the pump dry or allowing the media to be completely drained (cavitation).

(3) Do not operate the pump continuously for more than 2 minutes with the discharge valve closed, to prevent overheating and failure of the magnetic drive.

 

4. Not for Use in Pressurized Systems:

Due to the existence of certain clearances in the pump cavity and the use of "static bearings," this series of pumps must absolutely not be used in pressurized systems (neither positive pressure nor vacuum/negative pressure is acceptable).

 

5. Timely Cleaning:​

For media that are prone to sedimentation or crystallization, clean the pump promptly after use and drain any residual liquid from the pump.

 

6. Regular Inspection:​

After 1000 hours of normal operation, disassemble and inspect the wear of the bearings and the end face dynamic ring. Replace any worn-out vulnerable parts that are no longer suitable for use.

magnetic drive pumps

 

7. Inlet Filtration:​

If the pumped medium contains solid particles, install a strainer at the pump inlet. If it contains ferromagnetic particles, a magnetic filter is required.

 

8. Operating Environment:​

The ambient temperature during pump operation should be less than 40°C, and the motor temperature rise should not exceed 75°C.

 

9. Media and Temperature Limits:​

The pumped medium and its temperature must be within the allowable range of the pump materials. For engineering plastic pumps, the temperature should be <60°C; for metal pumps, <100°C. The suction pressure should not exceed 0.2MPa, the maximum working pressure is 1.6MPa, for liquids with a density not greater than 1600 kg/m³ and a viscosity not greater than 30 x 10⁻⁶ m²/s, and which do not contain hard particles or fibers.

High-temperature magnetic drive pumps replace dynamic seals with static seals, making the pump's wetted parts fully enclosed. This solves the unavoidable running, dripping, and leaking issues associated with the mechanical seals of other pumps. Manufactured using highly corrosion-resistant materials such as engineering plastics, alumina ceramics, and stainless steel, these pumps offer excellent corrosion resistance and ensure the pumped media remains uncontaminated.

Analysis and Troubleshooting of Seven Common Failures in Stainless Steel Submersible Pumps

 

Stainless steel submersible pumps are widely used in drainage applications across industries such as pharmaceuticals, environmental protection, food, chemical, and power due to their characteristics of corrosion resistance, hygiene, energy efficiency, environmental friendliness, non-clogging, high flow rate, and strong passage capability. Anhui Shengshi Datang will study together with everyone.

I. Common Causes and Solutions for Insufficient Flow or No Water Output in Stainless Steel Submersible Pumps:

1. The installation height of the pump is too high, resulting in insufficient impeller immersion depth and reduced water output. Control the allowable deviation of the installation elevation and avoid arbitrary adjustments.

2. The pump rotates in the reverse direction. Before trial operation, run the motor without load to ensure the rotation direction matches the pump. If this occurs during operation, check whether the power phase sequence has changed.

3. The outlet valve cannot open. Inspect the valve and perform regular maintenance.

4. The outlet pipeline is blocked, or the impeller is clogged. Clear blockages in the pipeline and impeller, and regularly remove debris from the reservoir.

5. The lower wear ring of the pump is severely worn or blocked by debris. Clean the debris or replace the wear ring.

6. The density or viscosity of the pumped liquid is too high. Identify the cause of the change in liquid properties and address it.

7. The impeller is detached or damaged. Reinforce or replace the impeller.

8. When multiple pumps share a common discharge pipeline, a check valve is not installed or the check valve is not sealing properly. Install or replace the check valve after inspection.

II. Causes of Abnormal Vibration and Instability During Operation of Stainless Steel Submersible Pumps:

1. The anchor bolts of the pump base are not tightened or have become loose. Tighten all anchor bolts evenly.

2. The outlet pipeline lacks independent support, causing pipeline vibration to affect the pump. Provide independent and stable support for the outlet pipeline, ensuring the pump’s outlet flange does not bear weight.

3. The impeller is unbalanced, damaged, or loosely installed. Repair or replace the impeller.

4. The upper or lower bearings of the pump are damaged. Replace the bearings.

III. Causes of Overcurrent, Motor Overload, or Overheating in Stainless Steel Submersible Pumps:

1. The operating voltage is too low or too high. Check the power supply voltage and adjust it.

2. There is friction between rotating and stationary parts inside the pump, or between the impeller and the seal ring. Identify the location of the friction and resolve the issue.

3. Low head and high flow cause a mismatch between the motor power and the pump characteristics. Adjust the valve to reduce the flow, ensuring the motor power matches the pump.

4. The pumped liquid has high density or viscosity. Investigate the cause of the change in liquid properties and adjust the pump’s operating conditions.

5. The bearings are damaged. Replace the bearings at both ends of the motor.

IV. Causes and Solutions for Low Insulation Resistance in Stainless Steel Submersible Pumps:

1. The cable ends were submerged during installation, or the power or signal cable was damaged, allowing water ingress. Replace the cable or signal wire, and dry the motor.

2. The mechanical seal is worn or not properly installed. Replace the upper and lower mechanical seals, and dry the motor.

3. The O-rings have aged and lost their function. Replace all sealing rings and dry the motor.

V. Causes and Solutions for Visible Water Leakage in Pipes or Flange Connections of Stainless Steel Submersible Pump Systems:

1. The pipeline itself has defects and was not pressure-tested.

2. The gasket connection at the flange joint was not properly handled.

3. The flange bolts were not tightened correctly. Repair or replace defective pipes, realign misaligned pipes, and ensure bolts are inserted and tightened freely. After installation, conduct a pressure and leakage test on the entire system. Replace components as necessary.

VI. Internal Leakage in Stainless Steel Submersible Pumps:

Leakage in the pump can lead to insulation failure, bearing damage, alarm activation, and forced shutdown. The main causes include failure of dynamic seals (mechanical seals) or static seals (cable inlet seals, O-rings), and damage to power or signal cables allowing water ingress. Alarms such as water immersion, leakage, or humidity may trigger shutdowns. Before installation, inspect the quality of all sealing components. Ensure proper contact between sealing surfaces during installation. Before operation, check the motor’s phase-to-phase and ground insulation resistance, and ensure all alarm sensors are functional. If leakage occurs during operation, replace all damaged seals and cables, and dry the motor. Do not reuse disassembled seals or cables.

VII. Reverse Rotation After Shutdown of Stainless Steel Submersible Pumps:

1. Reverse rotation occurs after the pump motor is powered off, mainly due to failure of the check valve or flap valve in the outlet pipeline.

2. Before installation, inspect the check valve for correct orientation and ensure the flap valve is centered and operates flexibly. Regularly inspect the check valve or flap valve during operation, and repair or replace damaged components with quality parts.

 

Performance Characteristics of Fluoroplastic Self-Priming Pumps

 

Fluoroplastic self-priming pumps, also known as the TIZF series fluoroplastic self-priming pumps, are designed and manufactured in accordance with international standards and the manufacturing processes for non-metallic pumps. The pump structure adopts a self-priming design. The pump casing consists of a metal shell lined with fluoroplastic, and all wetted parts are made of fluoroplastic alloy. Components like the pump cover and impeller are manufactured by integrally sintering and pressing metal inserts coated with fluoroplastic. The shaft seal utilizes an advanced external bellows mechanical seal. The stationary ring is made of 99.9% alumina ceramic (or silicon nitride), and the rotating ring is made of PTFE-filled material, ensuring highly stable corrosion resistance, wear resistance, and sealing performance.

 

A fluoroplastic self-priming pump does not require priming before startup (although the initial installation still requires priming). After a short period of operation, the pump can draw fluid up and commence normal operation through its own action.

 

Fluoroplastic self-priming pumps can be classified by their operating principle into the following categories:

1.Gas-liquid mixing type (including internal mixing and external mixing).

2.Water ring type.

3.Jet type (including liquid jet and gas jet).

 

Fluoroplastic self-priming pumps

 

Working process of the gas-liquid mixing self-priming pump: Due to the special structure of the pump casing, a certain amount of water remains in the pump after it stops. When the pump is started again, the rotation of the impeller fully mixes the air in the suction line with the water. This mixture is discharged into the gas-water separation chamber. The gas in the upper part of the separation chamber escapes, while the water in the lower part returns to the impeller to mix again with the remaining air in the suction line. This process continues until all gas in the pump and suction line is expelled, completing the self-priming process and allowing normal pumping.

 

Water ring self-priming pumps​ integrate a water ring and the pump impeller within a single housing, using the water ring to expel gas and achieve self-priming. Once the pump operates normally, the passage between the water ring and the impeller can be closed off via a valve, and the liquid within the water ring can be drained.

 

Jet self-priming pumps: consist of a centrifugal pump combined with a jet pump (or ejector). They rely on the ejector device to create a vacuum at the nozzle to achieve suction.

 

The self-priming height of a fluoroplastic self-priming pump is related to factors such as the front impeller seal clearance, pump speed, and liquid level height in the separation chamber. A smaller front impeller seal clearance results in a greater self-priming height, typically set between 0.3-0.5 mm. If the clearance increases, besides a decrease in self-priming height, the pump's head and efficiency also reduce. The self-priming height increases with the rise in the impeller's peripheral velocity (u2). However, once the maximum self-priming height is reached, further speed increases will not raise the height but only shorten the priming time. If the speed decreases, the self-priming height also decreases. Under other constant conditions, the self-priming height increases with a higher stored water level (but should not exceed the optimal water level for the separation chamber).

 

To better facilitate gas-liquid mixing within the self-priming pump, the impeller should have fewer blades, increasing the pitch of the blade grid. It is also advisable to use a semi-open impeller (or an impeller with wider flow channels), as this allows the returning water to penetrate more deeply into the impeller blade grid.

Most fluoroplastic self-priming pumps are matched with internal combustion engines and mounted on movable carts, making them suitable for field operations.

 

What is the working principle of a fluoroplastic self-priming pump?

For a standard centrifugal pump, if the suction liquid level is below the impeller, it must be primed with water before startup, which is inconvenient. To retain water in the pump, a foot valve is required at the inlet of the suction pipe, but this valve causes significant hydraulic losses during operation.

A self-priming pump, as described above, does not require priming before startup (except for the initial installation). After a short operation, it can draw fluid up and begin normal operation. The classification and working principles of the different self-priming types (gas-liquid mixing, water ring, jet) are as previously detailed.

Each metre of diamond wire contains 37 beads. These diamond beads act as abrasives, completing the cut under the cooling and cleaning action of a water flow, with excess material discharged with the water flow.

To optimise diamond wire efficiency, the following operational practices are recommended:
Shape the top and bottom surfaces of the block prior to sawing.
The block should be positioned on two supports and secured with cement bonding.
