Progressive Cavity Pumps for Industrial, Sanitary & Municipal Applications

Progressive cavity pumps can move thin liquids like water, as well as highly viscous and abrasive fluids such as sludge, adhesives, resins, oils, and slurries with solids.

No. These pumps should not be run dry as it can damage the stator and rotor. A run-dry protection system is often recommended.

Capacities vary by model and manufacturer, but progressive cavity pumps can typically handle flows from a few gallons per minute up to thousands, with pressures exceeding 700 PSI in some designs.

Routine inspection of the rotor, stator, seals, and joints is essential. Proper lubrication, alignment, and timely replacement of worn parts will extend pump life.
We also offer pump repair and maintenance services.

Yes. We supply OEM and high-quality replacement parts, including rotors, stators, seals, and joints, to keep your pumps running reliably.

Yes. Our technicians can install new pumps, troubleshoot issues, and perform maintenance or rebuilds at your facility.

A progressive cavity pump is a positive displacement pump that moves fluid through a sequence of sealed cavities formed between a rotating rotor and an elastomeric stator.

It works by progressing cavities from the suction to the discharge end as the rotor turns eccentrically inside the stator, producing continuous, low-pulsation flow.

Potential limitations include stator wear, sensitivity to dry running, speed-related wear rates, and elastomer compatibility constraints. These factors are application-dependent.

Manufacturers include NETZSCH, Moyno, and other OEMs producing industrial positive displacement pumps.

Gear pumps use meshing gears to move fluid and are typically suited for clean, lubricating fluids. Progressive cavity pumps use cavity progression and are often applied to viscous, shear-sensitive, or solids-containing fluids. Performance characteristics differ based on application requirements.
