Solids Handling Pumps & Stirrers

Reduce clogging and wear

Solids handling pumps are designed to move fibrous, thick, and grit-laden materials without clogging or excessive wear. Different pump types achieve this through specialised designs:

Vortex Pumps: Use a recessed impeller to create a vortex, allowing solids to pass with minimal contact, reducing wear.
Progressive Cavity Pumps: Utilise a helical rotor-stator system to move thick, shear-sensitive materials like sludge and food waste.
Self-Priming Centrifugal Pumps: Handle solids while allowing easy re-priming, making them ideal for intermittent operation in wastewater and industrial drainage.
Twin Screw Pumps: Offer smooth, pulsation-free flow, ideal for viscous and shear-sensitive fluids in food processing and chemical industries.

Prime Fluid Management can recommend the solids-handling pump or stirrer to best meet your needs. Take a look at our range below.
