Peristaltic Pumps (Hose Pumps)
A peristaltic pump is a hose pump that uses rotating shoes to compress a reinforced rubber hose. This creates continuous suction at the inlet and pushes product to the outlet. The casing contains a food-grade lubricant to reduce friction and support performance. The pumped product is in contact only with the inside of the rubber hose, allowing a wide range of reactive products to be handled.
Application
Pump for transfer, emptying or taking samples of viscous and/or abrasive products. Also suitable for shear-sensitive media and liquids containing fragile ingredients. Examples: fruit concentrate, tomato sauce, mashed potatoes, egg white & yolk, natural flavouring, cream, milk and yogurt, water & salt mixtures, fats, gelatine, etc.
How it works
- Two shoes (180° apart) compress the reinforced rubber hose successively.
- Compression creates suction at inlet and positive displacement towards outlet.
- Flow is in direct linear relation to pump speed (wide capacity range with one pump).
- Product only contacts the hose interior—supporting reactive or sensitive media handling.

FAQ
Quick answers about hose pump operation and selection.
What makes a peristaltic pump suitable for abrasive or reactive products?
The pumped product contacts only the inside of the hose, while the casing uses food-grade lubricant to reduce friction. This supports a broad range of media including reactive products.
Can a peristaltic pump run dry?
Peristaltic pumps are commonly selected for their ability to withstand dry running and their seal-less design. Always verify limits for your specific duty.
How do I choose between Tri-Clamp, SMS, and DIN flange connections?
Choose the connection standard that matches your plant piping and hygienic requirements. If unsure, share line standards and we’ll recommend the matching variant.
