This article will throw light on some aspects of peristaltic hose pumps, such as their design parts and what material they are made of, operation and maintenance features, benefits, applications, and the likes.


It is a common understanding that a peristaltic hose pump is made for heavy duty purposes only. However, in reality the application of this pump type is far beyond that. It is suitable for a number of industrial applications; besides, at times it may not seem to be the best pump for a given task, but still it delivers performance beyond expectation.

Pump’s Parts and Materials

The following is a list of its parts and components:

  • Pump housing made of cast iron
  • Rotor made of cast iron
  • Rotor shoes made of aluminum
  • Inserts made of stainless steel
  • Flanges made of mild steel
  • Base plate made of carbon steel
  • Bearing cartridge made of cast iron and its shaft made of tensile
  • Lubricant, a mixture of certain materials
  • Pump hose made of natural rubber, NBR, Ethylene-Propylene-Diene-Monomer (EPDM), and CSM
Simplistic Operation and Maintenance

A peristaltic hose pump is very simple in design. Pumps with complicated structures and parts are difficult to maintain as they incur huge costs in repair and replacement quite often. However, a peristaltic pump is cost efficient both in operation and maintenance. It does not have seals, flush water, or valves; therefore, the cost of maintenance is low.

The only wearing part is the inner hose which can be replaced easily at regular intervals and essentially incurs little cost. The pump’s ability to give a dry run makes it more efficient so that it doesn’t undergo enormous damage if left un-attended. It is a rugged pump, equally effective in heavy duty and shear-sensitive applications.

It also gives a fully reversible flow. In case there are chances of clogged material that is being pumped, the flow can be converted to reverse mode and eventually choked media will come out. This pump offers high volumetric flow so that more quantity of fluid can be pumped within one cycle.

3 E’s

A peristaltic hose pump is certainly a 3E’s device. It is made Effective, Efficient, and Economical. This pump type is capable of handling a number of fluid types with effectiveness and efficiency, and besides that, it is economical too. For extensive industrial use no other pump type can be more economical and cost effective than a peristaltic hose pump.

A peristaltic pump is a self-priming machine, it is also good for dosing applications. Irrespective of the industry, the applications of this pump are everywhere. However in a broad spectrum, it can handle the following types of media:

  • Highly dense or concentrated liquids
  • Shear-sensitive fluids
  • Highly viscous media
  • Abrasives
  • Corrosives
  • Chewy material
  • Crystallizing products
  • Food pastes
  • Carbon in pulp
  • Ceramics
  • Belt press feed
  • Minerals
  • Chemical slurries
  • Grout
  • Sludge
  • Paints and coatings
  • Scum and grease
  • Waste water

In a nutshell, this is a real versatile pump!
