FAQ – Frequently Asked Questions
We can provide spare parts for all Seepex progressive cavity pumps, you only need to provide the pump model and the corresponding Pos. No. .
Common wearing parts are: stator, rotor, connecting rod, joint grease, plug-in shaft, etc.
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. Of course, you can also provide the Seepex pump nameplate to us.
You need to provide the pump model (the pump label can be provided), serial number (optional), the position number of the part, and the description or name of the part. If there is nothing, you can provide the photos of the spare parts you need or the measured size.
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.
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:
- 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.
- 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.
