Super Spotlight on Progressive Cavity Pumps
We’ve had some interesting builds come through the factory over the past few days, including these Roto Progressive Cavity Pumps.
Check out these photos to see these Progressive Cavity pumps completed and ready to be shipped out – side ported for the large size pumps and vertical mounted motors for the extra smalls.
Both of these projects had space constraints onsite.
It’s always exciting working on these tough builds that push our skills and expertise – nothing beats seeing these pumpsets leave our doors, ready to power up your projects.
A key strength at Pump & Valve Specialties Ltd is our ability to match quality stock on hand with your application.

Progressive Cavity Pumps
Progressive Cavity Pumps (also known as Helical Rotor Pumps) are positive displace pumps that are typically used for pumping thick sludge and shear sensitive polymers. Flow is directly proportional to speed meaning they can be used to meter fluids.
They are also able to pump dirty and solids laden liquids with viscosities ranging from 1 cps (water like) up to 1,000,000cps.
Description
Progressive Cavity Pumps (also known as Helical Rotor Pumps) are positive displace pumps that are typically used for pumping thick sludge and shear sensitive polymers. Flow is directly proportional to speed meaning they can be used to meter fluids.
They are also able to pump dirty and solids laden liquids with viscosities ranging from 1 cps (water like) up to 1,000,000cps.
- Gentle and shear sensitive pumping action
- Able to pump viscosities ranging from 1 – 1,000,000cps
- Available in cast iron, stainless steel and duplex stainless steel
- Wide variety of rubber types available including nitrile, high nitrile, natural rubber, EPDM and viton
- Cardin Joint system used to remove the eccentric motion of the shaft. In essence it is an oversized universal joint of the type found in cars and trucks and is proven, compact and reliable and has a 24 month warranty.
- Zero leakage at low torque between the stator and rotor. Roto is one of the surprisingly few PC pump manufacturers that still manufacture their own stators and the process is precise and carefully controlled right from the mixing of the rubber through to controlling the 3 dimensional shrinkage of the rubber as it cools from the mould. This is important as if this seal line is not there it results in increased wear and reduced pressure and flow.
- Flows range from as low as 0.68l/h right up to 320m³/h and higher.
- Pressures from 0 bar to 48 bar. Typical PC pumps will develop 6 bar or pressure per stage so a single stage pump will develop 6 bar and a 2 stage pump will develop 12 bar and so on.
- Sewage sludge
- Polymer dosing
- Mine dewatering
- Dairy effluent pumping
- Chemical dosing
- Waste oil pumping
- Oil/water separator pumping
