Viscous Fluid Pumps | Gear & Progressive Cavity Pumps

We'll keep things flowing

Viscous fluid pumps are used across various industries where thick or semi-solid materials need to be transferred, mixed, or processed efficiently.

Selecting the right pump is crucial for maintaining flow efficiency, preventing clogging, and reducing wear. Prime Fluid Management supplies a range of pump types and models from, recognised manufacturers, to ensure we meet your unique industrial requirements.

Gear Pumps

Shifting oils, polymers and adhesives

Gear pumps work when two interlocking gears rotate to move fluid. They suit medium- to high-viscosity fluids, including oils, polymers, and adhesives.

High-pressure capability with precise dosing.
Compact and efficient for lubricating or non-abrasive viscous fluids.
Self-priming, positive displacement
Our brands: GVR Pumps

Progressive Cavity Pumps

Handling extreme viscosity

Progressive Cavity, or PC, pumps have a helical rotor that moves through a series of small chambers, maintaining consistent, low-pulsation flow.

Handles sludges, pastes, and solids-laden fluids
Low shear, ideal for fragile or shear-sensitive materials
Self-priming and highly efficient for high-viscosity applications
Our brands: Wangen
