Pump Type Overviews

Peristaltic pumps are a popular choice for applications where other pump types fail to meet the requirements i.e. highly viscous or solid laden mediums. In addition, the wide variety of materials that the inner tube is available in, along with the peristaltic hose pump’s seal-less design, means that even aggressive chemicals can be handled without the likelihood of leaks.

Rotary vanes pumps are part of the positive displacement pump family, designed for the transfer of clean low to medium viscosity fluids and fuels at relatively low pressures. Our sliding vane pump guide covers technical information concerning the mechanism by which the vane pump operates, advantages of the pump’s design and typical applications that vane pumps are often used for. Also included is a trouble shooting guide.

Flexible impeller pumps are a type of positive displacement pump, designed for the low pressure transfer, filling and dosing of a wide variety of fluids including shear sensitive and those containing solids. Our guide to the flexible vane pump design covers its working principle, benefits of the design and the applications that they are commonly used for. Also included is an impeller chemical compatibility chart.

Side channel pumps have a working principle that is a middle ground between the two main pump families; centrifugal and positive displacement. They are designed for low flow, high pressure applications concerning low viscosity, clean fluids including those being handled at high temperatures and containing a level of gas. This guide provides information on the design benefits and applications that these pumps are suited to.

Air operated diaphragm or AODD pumps as they are also referred to as, are a type of reciprocating positive displacement pump that are powered by compressed air rather than an electric motor that most other pump designs are. They are a versatile design capable of handling low and high viscosity fluids, including those with solids and more aggressive chemicals. Read this guide for more information on their working principle.

Gear pumps are one of the most popular types of positive displacement pump; with internal and external variations. They are commonly used for the transfer of high viscosity oils and other lubricating fluids at relatively high pressures. This guide gives a detailed insight into the working principle of both external and internal gear pumps and the applications they are typically chosen for.
