Peristaltic Pumps in Cape Town (A.K.A Liquid Hose Pumps)

Peristaltic pumps are a type of positive displacement pump that use rollers to compress a flexible hose and create a pumping action known as peristalsis. This pumping action moves a variety of fluids at controlled flow rates without the pump head making direct contact with the fluid being pumped. Peristaltic pumps work in chemical processing, water treatment, medical applications, and dosing applications. They are cost-effective, gentle pumping devices with the ability to run dry and suit abrasive or corrosive liquids. Our range of peristaltic hose pumps offers reliable performance for industrial and OEM pumping applications.

How Peristaltic Pumps Work and What a Peristaltic Pump Does

A peristaltic pump operates through positive displacement action. Inside the pump, rollers rotate along a pump tube or hose as they rotate. This compressing the tube creates a vacuum on the suction side of the pump. The fluid enters the inlet and moves smoothly through the flexible tube. The pump casing houses the pump head and rotor. Pumps operate by transferring kinetic energy through this simple but effective pumping action. The fluid’s viscosity or corrosive condition does not affect performance since the only wetted part is the hose. This design gives chemical compatibility across a wide range of chemicals, viscous fluids, dyes, and shear-sensitive media. The tube fitted inside the unit may be made from EPDM, nitrile, or natural rubber to ensure chemical compatibility and reliability.

Key Pump Features That Improve Meter Performance

Peristaltic pumps allow accurate control of flow rate and dose. The flow rate of a peristaltic pump depends on the rate of a peristaltic pump’s rotor speed and the length of the tube. These pumps allow proportional metering for chemical processing and sanitary dosing applications. Metering pumps using peristaltic technology provide precise delivery in intermittent or continuous operation. Some smaller pumps are designed to operate intermittently for medical applications or OEM systems. The design ensures gentle pumping with low pulsation. The hose pump is self-priming and capable of dry running. This pump can achieve reliable pump performance even under high-pressure conditions of up to 16 bar.

Managing Pulsation to Ensure Better Pump Performance

The roller pump design minimises pulsation by using multiple rollers inside the pump head. This smooths the flow rate and maintains accurate delivery. The pump’s compatibility with ancillary equipment such as valves and meters further improves performance. EPDM, NBR, Hypalon, PTFE, and natural rubber hoses are available to ensure compatibility with the fluid being pumped. Using the correct pump selection ensures long service life and prevents failure. ATEX-rated units provide safety in corrosive or explosive pumping applications. Each parastaltic pump operates effectively for both abrasive and corrosive liquids without the need for complex fittings. A lubricant is often applied inside the pump casing to reduce wear and keep the hose pumping action efficient.

Using Peristaltic Pumps in Water Treatment Applications

Peristaltic pumps are widely used in water treatment pumping applications. They provide reliable flow control for dosing chlorine, chemicals, and other additives. These pumps operate smoothly and reduce the risk of contamination since only the hose is in contact with the liquid. They are suitable for municipal and industrial water treatment systems where reliability and easy maintenance are essential. Pumps allow dosing applications to be managed accurately with minimal maintenance. The pump can achieve consistent pump performance even with abrasive slurry or corrosive liquids. This makes them an ideal solution for water treatment plants in Cape Town.

How the Pump Handles Solids and Harsh Liquids

A peristaltic pump handles solids and abrasive slurries better than most positive displacement pumps. The compressing of the pump tube allows the pump to move viscous fluids and solids without clogging. The pumping action ensures the hose pump remains reliable in chemical processing, slurry handling, and dye transfer. The pump’s ability to run dry makes it suitable for challenging pumping applications. Smaller pumps and larger high-pressure units are both available, offering a wide range of peristaltic pump solutions. Tube pump models are common in medical applications where dosing and gentle pumping are needed. Whether you need a replacement for your current pump or a custom OEM solution, our peristaltic hose pumps are designed for cost-effective service.
