Products Description

Structural features

1.Progressive Cavity Pump Connecting Rod

As a professional progressive cavity pump manufacturer, we also produce high quality cavity pump connecting rods to guarantee top pump performances. We can customize the connecting rod to meet exact customer requirements, and in different structures, such as the asymmetrical connecting rod, taper connecting rod, or multi-layer connecting rod.

Weifang Subtor as a German Subtor invested company in China, offers wide range of progressive cavity pumps and connecting rod components. With German supported technology and rich marketing resources, Subtor provides quality PCP pumps as well as rotor stator parts for global clients.

2. Progressive Cavity Pump Stator

A stator is one of the most important components to a progressive cavity pump, and is often divided into two types: a rubber stator, or a rigid stator. We offer customized stators according to actual field conditions and the transmission medium.

1. Rubber stator: Stators are a vulnerable part of progressive cavity pump. When the stator surface becomes worn, the sealing performance between the rotor and the stator decreases, which results in a decreased flow. Different rubbers, such as NBR, NBRH, HNBR, EPDM and FKM with corrosion resistance and high temperature resistance need to be chosen to suit different mediums.

2. Rigid stator: Rigid stators include a metal stator or PTFE stator. A rigid stator is recommended in specialized work environments, such as the transportation of hot oil, high temperature bitumen, high temperature heavy oil, concentrated acid or alkali, and a high concentration of chloride ions.

Features of rigid stator

1. It features a high temperature resistance- up to 300℃.

2. The rigid stator can bear a high pressure medium. They feature a small torque and a single stage pressure of up to 12 bar.

3. In a progressive cavity pump with the same flow, a pump with a rigid stator will be smaller than one with a rubber stator.

4. Metal stators feature a quick heat dissipation, no abrasion and a longer service life.

5. PTFE stators are suitable for strong acidic and alkaline environments, as well as mediums with a high chlorine content.

Introduction of common stator material

Material	Corrosion resistance	Swelling resistance	Abrasion resistance	High temperature resistance	Temperature range	Suitable Application
NBR	general	good	general	general	+110℃	Petroleum, sewage, food and beverage, chemical, or paper making industry
NBRH	good	excellent	good	general	+120℃	Oil refining, chemical, waste water
EPDM	good	poor	good	general	+120℃	Chemical industry, chemical reagent, paper making
FKM	excellent	excellent	poor	excellent	+180℃	High temperature and corrosive fluid
HNBR	excellent	good	good	excellent	+170℃	Petroleum, petrochemical and chemical industry
PTFE	excellent	excellent	poor	excellent	+230℃	Acid & alkali and other strong corrosive medium, high temperature and high hygiene requirements of the food and beverage industry

Note: All information above can be combined based on specific requirements, the particular medium that needs moving, and the working conditions. Please contact us for more details.

3. Progressive Cavity Pump Rotor

We can design and process rotors in different geometric shapes to meet specific customer requirements. The metal materials used can also be treated for surface hardening or vacuum heating, with the hardness of the metal after treatment reaching HRC60-65°. The surface can also be sprayed with a tungsten carbide or chromium carbide in specific industries to give the surface a hardness of HRC68° in order to improve its wear resistance.

Material	Corrosion resistance	Abrasion resistance	Chlorine resistant Cl- concentration(ppm)	Suitable Application
Carbon steel	general	general	poor	For abrasive but noncorrosive fluid, cannot be used for food
Carbon steel (harden treatment)	general	excellent	poor	For non-corrosive but highly abrasive fluid
SS420 (harden treatment)	general	good	poor	For slightly corrosive and abrasive fluid
SS304	good	general	< 100	Can be used in the food industry and for non-corrosive acidic fluid
SS304 (harden treatment)	good	good	< 100	For corrosive and abrasive fluid, cannot be used for food
SS316	good	general	100~2000	Can be used in the food industry and for non-abrasive acid fluid
SS316 (harden treatment)	excellent	excellent	100~2000	For corrosive and abrasive fluid, cannot be used for food
Duplex SS	excellent	excellent	1000~40000	For corrosive fluid with high content of Cl ion but non-abrasive acid fluid
Duplex SS (harden treatment)	excellent	excellent	1000~40000	For corrosive fluid with high content of Cl ion and abrasive acid fluid
