Energy-Saving, Easy to Service, Robust: How to Benefit From a Peristaltic Pump

What is a peristaltic pump?

A peristaltic pump, also known as a hose pump, is a positive displacement pump used to pump liquids and pastes gently. It works based on a rotating mechanism that compresses a flexible hose, continuously moving the medium forward. This technology ensures pulsation-free and precise dosing without the pumped medium coming into direct contact with moving parts of the pump. As a result, a peristaltic pump is particularly suitable for applications where hygiene, sterility and gentle handling of the pumped media are essential.

Advantages of the peristaltic pump

The peristaltic pump technology offers numerous advantages, making it a favoured choice in many industrial sectors. One of the most important advantages is the protection of the pumped media, as it does not come into contact with the pump's mechanical parts, thus preventing contamination. This makes peristaltic pumps ideal for hygienically sensitive areas such as the food, pharmaceutical and biotechnology industries. In addition, a peristaltic pump is characterised by its ease of maintenance and cleaning, as you can change the hose quickly and easily if necessary. The robust design and the ability to pump abrasive, viscous and solids-laden media also contribute to the durability and reliability of these pumps. In addition, peristaltic pumps offer precise and pulsation-free dosing.

Areas of application for the peristaltic pump

Thanks to their versatility and ability to convey different media gently and precisely, peristaltic pumps are used in numerous other industries and applications. In the food and beverage industry, for example, they are used to pump viscous liquids, pastes and sensitive products without affecting the structure of the medium. Peristaltic pumps are ideal for sterile applications in the pharmaceutical and biotechnology industries. They prevent contamination and ensure hygienic pumping. However, you can also use peristaltic pumps in the chemical industry to safely transport aggressive, abrasive or sensitive chemicals, for example. In addition, a peristaltic pump in wastewater treatment and environmental technology offers the option of reliably pumping sludge, slag and other solids-laden media. The ability to be used flexibly in different pressure ranges and flow rates makes peristaltic pumps a universal solution for numerous demanding applications.

Function of the peristaltic pump

A peristaltic pump works based on the principle of peristaltic movement, in which a flexible hose is repeatedly compressed and relaxed by a rotating element, usually rollers or shoes. This peristaltic principle is similar to the natural muscle movement in the human digestive tract. The rotation of the pump wheel presses the rollers against the hose, causing the pumped medium inside the hose to be transported continuously in one direction. When the hose returns to its original form behind the rollers, a vacuum draws a new medium into it. This process ensures even, pulsation-free delivery and precise dosing. As the medium only comes into contact with the inner part of the hose, the risk of contamination is also significantly minimised. It also makes it easier for you to clean and maintain the pump.

Peristaltic pump compared to other pump types

Peristaltic pumps offer unique advantages compared to other pump types, making them the preferred choice in many applications. In contrast to the piston, gear or centrifugal pumps, where the pumped medium comes into direct contact with the pump's mechanical parts, with peristaltic pumps, the medium is transported only through a flexible hose. This significantly reduces your risk of contamination. While centrifugal pumps efficiently pump large quantities and delivery heads, peristaltic pumps offer you precise and pulsation-free dosing. This makes them particularly suitable for accurate dosing and filling processes. Compared to gear pumps, which are sensitive to abrasive and viscous media, a peristaltic pump is also particularly robust. This means you can pump solids-laden and viscous media without any problems. Another decisive advantage that a peristaltic pump offers you is the ease of maintenance. As the hose is the only wearing part, maintenance and servicing costs are significantly lower than those of pump types.
