Industrial Peristaltic Pumps

Peristaltic Pumps belong to the Positive Displacement (PD) family of pumps.

They are ideal for:

• Accurate dosing, as each cycle delivers a fixed volume; flow rate is controlled by rotation speed (RPM) and hose diameter.
• High-viscosity fluids/high dry matter sludges; the high-pressure displacement makes easy work of difficult sludge and pastes.
• Energy efficiency over a wide duty range.
• Two-way pumping – fill and empty vessels with the same equipment setup.
• Shear-sensitive fluids and fibrous matter prone to ‘ragging’; the slower, large diameter rotation creates less shear friction and there’s nothing for fibres to wrap around.

These pumps are sometimes referred to as Roller pumps, Tube pumps or Rotary Pumps which are all very appropriate names. Their simple design consists of a flexible pump tube fitted in a ‘C’ shape inside a circular pump casing. The pumped fluid is squeezed along through the hose by a rotating spoke assembly. This makes them suitable for handling abrasive fluids, slurries containing solids, and highly viscous sludges.

Particular advantages of peristaltic pumps include safe dry-running, easy CIP, wide viscosity range, large solids-passage, self-priming ability, and outstanding MTBM.
