Peristaltic & Lobe Pumps
Positive displacement pumps for viscous, shear sensitive, solid-containing or food applications.
Peristaltic Pumps
What Is a Peristaltic Pump?
A peristaltic pump is a positive displacement pump that moves fluid through a flexible hose or tube by compressing it with rotating rollers or shoes. It ensures gentle, contamination-free, leak-free dosing.
-
Fluid only contacts the tube, not the pump body → excellent for corrosive chemicals
-
Self-priming and dry-running capable
-
Reversible flow direction
-
Easy maintenance (just replace the tube)
-
Accurate and pulseless flow at low flow rates
How a Peristaltic Pump Works
-
Rollers (or shoes) compress a flexible tube
-
The compression forces the fluid forward
-
After the roller passes, the tube rebounds, creating suction
-
The fluid never touches mechanical parts

Lobe Pumps
What Is a Lobe Pump?
A lobe pump is a positive displacement pump that uses two rotating lobes to move fluid through the pump cavity. It provides a smooth, pulsation-reduced flow and handles viscous, shear-sensitive, and hygienic fluids.
-
Smooth, low-shear pumping
-
Handles large solids without damage
-
Stainless steel construction suitable for hygienic and food applications
-
Long service life if operated with proper clearances
-
Flow rates till 400 m³/h
-
Delivery head till 10 Bar
-
Viscosity till 250000 cps
How a Lobe Pump Works
-
Two synchronized lobes rotate in opposite directions
-
Fluid enters the cavity between the lobes
-
Rotation carries fluid around the chamber
-
Fluid is discharged smoothly into the outlet
Advantages of Lobe Pumps
-
Low-shear pumping
-
Hygienic designs available for food & pharma
-
Good for viscous fluids, pastes, slurries
-
Very smooth flow
-
CIP/SIP compatibility
