Peristaltic Pump – Efficient Pumping of Abrasive Media
Robust, low-maintenance, and ideal for demanding applications: Peristaltic pumps impress with their versatility and reliability. Whether abrasive media, highly viscous substances, or sensitive liquids, a peristaltic pump does not require costly seals, is resistant to dry running, and impresses with minimal wear.
Thanks to its simple operating principle, it is ideal for processes with high requirements in terms of reliability, hygiene, and ease of maintenance. Discover the advantages of the peristaltic pump. We will show you how to benefit.
What is a peristaltic pump?
Customised Consulting
The peristaltic or hose pump belongs to the family of rotary positive displacement pumps. Its operating principle is based on the mechanical deformation of a flexible hose by rotating rollers or sliding shoes. This creates an uninterrupted, pulsating flow generated by compressing and relaxing the hose. The medium is located only inside the hose and does not come into contact with other pump components. This design reduces the risk of leakage and enables the pumping of aggressive, solid-laden or hygienically sensitive fluids – without the use of rotating seals or valves.
Advantages of a peristaltic pump
Peristaltic pumps offer a wide range of technical advantages, making them attractive for a variety of industries:
- Dry-running operation without additional protection systems
- Media contact only via the hose
- Steady flow, even with gas-laden or highly viscous substances
- Reversible for flexible use
- Easy hose replacement with minimal maintenance
- Valve-free design for high process reliability
These features make the peristaltic pump an exceptionally reliable solution for industrial applications. It enables you to dose small quantities and convey large volumes precisely. Even under difficult operating conditions, it guarantees a safe and low-maintenance conveying process.
Areas of application for peristaltic pumps
Thanks to their properties, peristaltic pumps are used in various industries. They are particularly common in water and wastewater management, conveying chemicals, sludge, flocculants or lime milk. In mining and raw material extraction, they transport abrasive suspensions and ore slurries even under extreme conditions. In the chemical industry, they enable you to safely convey aggressive, toxic or sensitive media without the product coming into contact with mechanically stressed components. Peristaltic pumps also offer numerous advantages in the food and beverage industry. They convey hygienically sensitive flavours, concentrates, yeast solutions or viscous liquids with the highest precision. In the paper and pulp industry, they are used for dosing additives, colours and coatings. Wherever you need maximum process reliability, long service life and low-maintenance operation, the peristaltic pump is the right choice.
The solution for demanding processes
Peristaltic pumps offer maximum flexibility thanks to their construction. Depending on the material of the pump tube, a wide variety of media can be reliably conveyed, even with high solids content, strong temperature fluctuations or sensitive product structures. Maintenance remains predictable and straightforward, as no seals or complex valve systems are involved. Peristaltic pumps demonstrate their advantages, particularly in applications where other pump types reach their limits. They are compact, robust and operate reliably under changing operating conditions.
