Industrial Peristaltic Pumps & Hose Pumps
Peristaltic pumps are positive displacement pumps designed to transfer a wide range of fluids using a flexible hose or tube. Also commonly known as hose pumps, they provide a gentle pumping action that can be particularly useful for shear-sensitive products, fluids containing solids and applications requiring accurate dosing.
Dura Pump supplies peristaltic pumps for industrial fluid-handling applications, with different hose materials and configurations available to suit varying products, chemicals, flow rates and operating requirements.
- Hygienic options available
- Suitable for fluids with high solids content
- Accurate and high-volume dosing capability
- Gentle pumping action for shear-sensitive products
- Dry-running capability
- High suction lift capability
What Is a Peristaltic Pump and How Does It Work?
A peristaltic pump is a positive displacement pump that moves fluid through a flexible hose or tube. The fluid remains contained within the tubing while a rotating set of rollers or shoes progressively compresses the hose.
As a roller moves across the flexible tube, it compresses the hose and pushes the fluid forward. Once the roller passes, the hose returns to its normal shape, creating suction that draws more fluid into the pump and allows the cycle to continue.
Peristaltic hose pumps typically use two or more rollers or shoes and can operate continuously or as part of a dosing system where controlled quantities of fluid need to be transferred.
Peristaltic Tubing Pumps and Hose Pumps
Peristaltic tubing pumps and peristaltic hose pumps work on the same basic operating principle, using compression of a flexible tube or hose to move fluid through the pump. The hose or tubing is therefore a key component of the pump and needs to be selected according to the fluid being handled and the operating conditions.
The peristaltic pump range available through Dura Pump includes different hose materials to support a variety of product and chemical applications. Selecting the appropriate peristaltic tubing pump or hose pump therefore depends on factors including the fluid, required flow rate, pressure and material compatibility.

Peristaltic Pump FAQs
A peristaltic pump is a positive displacement pump that moves fluid through a flexible hose or tube. Rollers or shoes compress the tubing in sequence, moving the fluid through the pump while keeping it contained within the hose.
A peristaltic hose pump uses a flexible hose that is compressed by rotating rollers or shoes to move fluid. Peristaltic pumps are therefore also commonly referred to as hose pumps.
Peristaltic pumps can be used for continuous fluid transfer or dosing applications. The pumps available through Dura Pump can handle applications involving shear-sensitive products, abrasive fluids, solids and accurate dosing requirements.
The peristaltic pumps described on this page have dry-running capability, with the existing range including externally lubricated hose designs.
Both use the same basic peristaltic operating principle, where a flexible tube or hose is compressed to move fluid. The most appropriate configuration depends on the fluid, required flow, pressure and operating conditions.
The appropriate pump depends on factors including required flow rate, pressure, fluid characteristics, solids content and material compatibility. Dura Pump can help assess these requirements and identify a suitable pump configuration.
