Send us a nameplate photo, a part number or your specification. We identify exactly what you need.
The right material
We match materials, seals and elastomers to your medium, temperature and duty.
Why it failed
If parts keep failing, we look for the cause, such as dry running, the wrong material or excess pressure, and suggest a fix.
The whole system
Where equipment is undersized or badly installed, our engineers can review the selection and the installation.

Specialist range
Progressive cavity (mono) pump parts
A progressive cavity pump moves fluid with a helical metal rotor turning inside a rubber stator. It gives a smooth, pulsation-free flow and copes with thick, abrasive or solids-laden fluids, which is why it is used so widely in water treatment, food and chemical plants. The rotor and stator are in constant contact, so they are the main wear parts.
- Rotors (stainless steel or hard-chrome plated) and stators
- Coupling rods, pin joints, pins, bushes and sleeves
- Drive shafts, shaft sleeves and stainless steel parts
Made to fit pumps from the leading manufacturers, including NETZSCH™, ALLWEILER™ and SEEPEX™.
