Hose pump for pumping demanding liquids and sludges

A hose pump is a positive displacement pump where a flexible hose is compressed by a rotating operating element. This moves the liquid forward inside the hose. This operating principle also makes the hose pump self-priming. In general, hose pumps are used in applications with low pressure and low flow rates. Hose pumps are used, for example, in the mining industry, food production processes and wastewater plants.
When selecting a hose pump, it is important to pay special attention to choosing the correct hose material so that it is chemically resistant to the pumped medium and sufficiently wear-resistant. The pumped medium also determines, for example, the required pulsation dampeners, while the application and operating method define other necessary accessories, such as frequency converters. The hoses for our hose pumps are also available in food-approved materials.

A hose pump works with a compression mechanism, where pressure is applied to the hose using rollers or a shoe. Since the liquid does not come into contact with the pump structure itself, a hose pump is highly suitable for handling corrosive, viscous and solids-containing liquids.

BPI-Chempump’s hose pumps are made from durable materials that ensure a long service life and excellent reliability in demanding conditions. A hose pump has a simple structure, which minimises the need for maintenance, and the pumps can be serviced quickly without special tools. This reduces downtime and brings significant savings in the long term.

Hose pumps are especially useful when the transferred medium contains solids or is chemically aggressive. This makes them an excellent choice for the chemical industry, water treatment plants, food production and the pharmaceutical industry, for example. In addition, the closed structure of the hose pump prevents contamination of liquids, which is important in applications that require a clean process. Food-approved materials are also available for hose pump hoses.

Compared to traditional rotating pumps, a hose pump offers significant benefits. First, its operating principle reduces wear because no moving parts are in contact with the transferred medium. This extends the pump’s service life and reduces maintenance costs. Second, hose pumps also operate reliably during dry running, which reduces the risk of damage in situations where liquid supply is temporarily interrupted.

Thanks to these features, a hose pump is an investment that quickly pays for itself through operational reliability and cost efficiency.
