The Stator of a Progressive Cavity Pump
The stator is mostly made of rubber. Because it needs to form a closed meshing cavity with the rubber stator, it is an interference fit with the rotor. When the rotor (main shaft) rotates and causes continuous friction, it will wear naturally.
The Rotor of a Progressive Cavity Pump
The Progressive cavity pump rotor (also known as the main shaft) is mostly made of stainless steel, and can be selectively plated with chrome;
Due to its meshing relationship with the characteristic geometry of the stator, in addition to natural wear, it is also whether the conveyed medium contains solid particles and corrosive.
The Coupling Rod of a Progressive Cavity Pump
The coupling rod connects the rotor and the drive shaft. When the motor is running, the drive shaft drives the coupling rod, and the coupling rod then drives the rotor to play a transmission role. Except for the drive shaft, these mechanical components are located in the suction chamber of the pump.
The Drive Shaft of a Progressive Cavity Pump
The drive shaft is generally connected to the drive end (reducer or various drive motors), and its wear is mostly caused by natural wear or changes in media working conditions.
The Universal Joint Assembly a Progressive Cavity Pump
The universal joint assembly is located at both ends of the coupling rod. It successfully connects the rotor and the drive shaft to the coupling rod more stably and firmly; Since the universal joint assembly consists of a variety of small spare parts, we need to check its seal regularly And lubrication.
Mechanical Seal
Mechanical seals are generally used to transport media with corrosion resistance, high moisture content or no particles or even a small amount of particles.
Advantages: Long life, no leakage, good vibration resistance, and a wide range of applications;
Disadvantages: Complex structure, high processing requirements, troublesome installation and replacement.
Packing Seal
The packing seal is mostly polytetrafluoroethylene packing, which is generally used for conveyor belt particles or media with low moisture content;
Advantages: The packing seal is wear-resistant, low cost, easy to install and replace;
Disadvantages: The medium will leak out of the stuffing box as drops and needs to be cleaned regularly.

Progressing cavity pump spare parts
Of course, when a problem occurs with your pump, spare parts need to be replaced. Usually the flow rate and pressure decrease, or the pump has abnormal noise, the pump does not rotate, the motor is rotating, and so on. At this time, we need to disassemble, inspect, remove and find the damaged parts of the pump. Then check the drawing to find the corresponding part description and position number.
Progressive cavity pump repair involves repairing or replacing the rotors of a progressive cavity pump, which are responsible for moving fluid through the pump. The repair process typically involves inspecting the rotors for damage, repairing any worn or damaged areas, and reassembling the pump with the repaired rotors. This ensures that the pump can continue to operate efficiently and effectively.
We have to consider many factors for this; Common reasons are system problems or wrong pump selection and material selection.
- If there is a problem with the system, the most common one is pump dry grinding;
- The wrong material selection will cause the spare parts to corrode and wear quickly.
- The wrong pump model selection will also cause the spare parts to wear out quickly, or even fail to work in serious cases.
If you need our help to determine the cause of the pump failure, you should provide the following information as far as possible: the fluid delivered by the pump, viscosity, temperature, physical and chemical properties, required flow rate, pressure, inlet conditions and pipe inner diameter.
We believe that the most important factor to consider is that your pump will be frequently or prematurely worn or damaged after replacement of new spare parts. If this situation still occurs after excluding system factors, you need to replace the pump with a new one, because it is likely that there is a problem with the selection of the pump. Of course, if you are replacing spare parts for the first time, you only need to consider the value of the replacement spare parts or the value of a brand new pump.
Tips：
General spare parts only need to replace the stator, rotor, and universal joint components. Occasionally, connecting rods, drive shafts, mechanical seals or packing are required.
Of course!
First of all, you have to determine whether you need to ensure the installation size, if necessary, we have to redesign the size of the pump to meet your working conditions and size.
Then you need to provide the most conventional information: the fluid delivered by the pump, viscosity, temperature, physical and chemical properties, required flow rate, outlet pressure, inlet pressure and pipe inner diameter.
The special geometry of the stator and rotor makes them cooperate with each other to form several mutually unconnected sealing cavities (cavities), and the cooperation between them is interference fit. When the motor operates, it will transfer power to the rotor and make the rotor move planetary along the axial direction, so as to push the sealing cavity to move to the discharge end and achieve the purpose of conveying liquid.
When the stator begins to wear, the fit gap between the rotor and stator will become larger, which may cause the rotor not to be too tight in the stator.
When the delivered fluid reaches the outlet of the pump, the discharge pressure of the circuit must be overcome;
However, the fluid will generally seek the path with the least resistance;
If the resistance of the seal chamber between the stator and the rotor is the minimum, part of the liquid will leak to the previous chamber.
Generally according to different working conditions and the medium to choose the right material.
It can be roughly divided into two factors: chemical compatibility and wear resistance.
Chemical compatibility: generally, the medium is chemically corrosive, in this case, we usually choose stainless steel (304, 316, duplex stainless steel) or titanium alloy material.
According to the chemical corrosivity, we will choose the appropriate stainless steel material.
Of course, stainless steel is also used in the food industry.
Wear resistance: when the medium contains fine particles, we need to fully consider its wear resistance;
And ways to improve wear resistance:
1. Use hard materials such as hardened tool steel (1.2436). It can also be subjected to heat treatment or nitriding treatment to improve its wear resistance.
2. Chrome plating on the surface of the rotor.（ We are plated with 5mm chromium on one side, and can also be plated according to your requirements.)
Whether it is hardened tool steel or stainless steel, we can electroplate on its surface.
Note: if the electroplated layer is damaged, the stator will be damaged.
Need more outlet pressure, please choose high pressure pump with bearing.
Generally our progressive cavity pump pressure is 0.6MPa as a unit level, and then gradually increase.
To increase the pressure, we will consider increasing the number of continuous seal chambers in the pump.
This also results in an increase in the number of seal lines between the stator and the rotor.
At a given pressure, when the number of sealing lines increases, the internal leakage rate of the pump will decrease.
