How to Select a Progressive Cavity Pump for Viscous Fluids

How to Select a Progressive Cavity Pump for Viscous Fluids, Sludge and Slurry

A progressive cavity pump can handle fluids that cause severe performance loss, excessive shear, or high power demand in a conventional centrifugal pump, but only when the rotor, stator, drive, and suction conditions are matched to the actual process duty. Many selection mistakes happen for the same reason: the fluid is treated as “thick” or…

How to Choose a Corrosion-Resistant Centrifugal Pump

Corrosion-Resistant Polypropylene Centrifugal Pumps: Benefits, Applications & How to Choose the Right Pump

A metal centrifugal pump handling hydrochloric acid, sodium hypochlorite, or another corrosive solution may appear satisfactory at first and still develop material loss, pitting, or leakage over time if its wetted materials are not compatible with the process fluid. This is one reason chemical, textile, electroplating, and effluent-treatment plants may consider polypropylene centrifugal pumps for…
