What are PC Pump Parts?
PC Pump Parts means the basic parts of a progressive cavity pump. Generally, when people mention screw pump parts, they normally refer to the wearable and replaceable parts on the progressive cavity pump. Well, the main basic pump parts include the Pressure Branch, Pump Rotor, pump Stator, Suction Casing, Coupling Rod, Driving Shaft, Universal Joint Set, etc.
What does a PC Pump mean? PC Pump usually refers to Progressive Cavity Pump or Progressing Cavity Pump. A progressive cavity pump is a type of positive displacement pump that works on the basis of the progress of the rotor. It is specially designed to handle highly viscous fluids and it is used for extremely tough pumping applications.
What are the
spare parts of progressive cavity pump?

We Supply the Universal Replacement Spare Parts for Single Screw Pumps
We Supply the Universal Replacement Spare Parts for Single Screw Pumps Progressive cavity pumps usually work in viscous fluid and mediums containing solid particles. In this condition, natural wear is normal and unavoidable. In addition, some abnormal damage will also cause some parts to be replaced. What we supply is the universal replacement of after-market spare parts for the popular progressive cavity pump brands. The brands are mainly NETZSCH, MONO, MOYNO, SEEPEX, ALLWEILER, PCM, etc.
For a single screw pump, the wearable and replaceable components are stators (stator Matiral:HNBR, NBR, EPDM, FKM), the helical rotor (steel alloy rotor Matiral 45#, 2Cr13, 304, 316L, 2205) ,coupling rods, driving shafts, sealing part and the universal joint set. These universal parts need to be replaced regularly. Generally, we supply all the replaceable pump parts types below with a full range of models:
The Progressive Cavity Pump Stator
The elastomer stator is one of the main parts of a progressive cavity pump. PC pump stators usually consist of two items: the shell and the lining. Specifically, the shell material normally is metal tube, let’s say seamless steel tube. For example, carbon steel with painting or stainless steel. And the lining is made of elastomer rubbers. According to your pump applications, you can select a type from NR, NBR, HNBR, FKM/FPM, EPDM, etc.
kynspump supplies the replacement parts of Netzsch Stators, NEMO Stators,SEEPEX Stators, MONO Stators, PCM Stators, etc. They are equivalent to the original pump stators of NETZSCH PC Pump, SEEPEX PC Pump, MONO PC Pump, MOYNO Screw Pump, Allweiler Eccentric Screw Pumps, etc. Our pump stators can be 100% compatible with the original progressive cavity pumps and their OEM spare rotors.
The Progressive Cavity Pump Rotor
the progressive cavity pump rotor is also known as the main shaft of a PC pump. It is mostly made of various grades of Tool Steel, Stainless Steel, Duplex Stainless Steel, Cr12MoV/1.2436, Hastelloy C276/C4, Titanium, etc.. Of course, some times ceramic rotors are also required by some special cavity pump applications. For steel types of PC pump rotors, they would be chromium plated or heat treated as request. Don’t hesitate to contact us and discuss the material type in accordance with your PC pump applications.
The Coupling Rods of progressive Cavity Pumps
the coupling rods are metal pump spare parts connecting the rotor and the driving shaft in a progressive cavity pump. In the eccentric screw pumps, the coupling rods are driven by the driving shafts when the motors are running. And then, the coupling rods drive the pump rotors to transmit the mediums
The Driving Shaft of Progressive Cavity Pump
The drive shaft is a metal pump part that locates between the coupling rod (by the universal joint set) and the driving end, Also referred to as the mechanical seal shaft.such as a reducer or various drive motors. It’s also a replaceable pump spare part. The drive shafts usually are corrupted by natural wear or media changes in working conditions.
The Universal Joint Set
The universal joint set is also known as the universal joint assembly. It consists of a set of spare parts and is located at both ends of the coupling rod. It generally enables a more stable and firm connection between the rotor, the drive shaft, and the coupling rod.
When the pump is running, the rotor performs planetary motion, and its axis is not collinear with the axis of the driving power source. Therefore, a special set of components must be designed between the rotor and the drive shaft, allowing the drive shaft of the power source to drive the rotor to achieve this planetary motion.such a group of pump parts are called the universal joint set.
Mechanical seal
Mechanical seal is the core sealing component of a screw pump (single progressive cavity pump), mainly installed between the pump shaft and the pump casing. Its core function can be summarized in one sentence: to prevent the medium inside the pump from leaking outward along the shaft, while stopping outside air and impurities from entering the pump chamber.
