Peristaltic Pumps

Laboratory Peristaltic Pumps for Accurate Liquid Transfer

Shop peristaltic pumps in Australia for laboratory liquid transfer, filling and dispensing. Compare programmable dosing, continuous-flow, multi-channel and high-flow models, together with compatible pump heads, tubing and accessories. Choose a system around your liquid, required flow rate and operating conditions.

How Does a Peristaltic Pump Work?

Peristaltic pumps use external rotating rollers to generate flow in a flexible tube. As the rollers rotate, they compress the tubing and propel the liquid along it. Each roller moves away as the next makes contact, continuing the pumping action. The fluid travels through an isolated tubing path and does not normally contact the pump mechanism.

Why Use a Peristaltic Pump?

Keeping the liquid inside the tubing reduces contact with pump components and helps minimise cross-contamination and clean-up. Worn tubing can be replaced, and changing the tubing between liquids can support your cleaning procedure. This design does not by itself make a process sterile or remove the need for filtration; select tubing and any filtration or cleaning steps to suit your application.

Choosing the Right Peristaltic Pump

Flow Rate

Match the required flow range to the pump, pump head and tubing combination. Flow can be adjusted through tubing size and pump speed in RPM. Liquid viscosity, tubing wear, suction conditions and discharge pressure can also affect delivery, so confirm performance for your operating conditions. Compare high-flow and industrial pumps when transferring larger volumes or working in more demanding environments.

Dosing and Continuous Flow

Continuous-flow pumps suit ongoing liquid transfer. Programmable dosing peristaltic pumps provide controls for repeated dispensing, with available functions varying by model. Check the required dose volume, interval, repeatability and calibration procedure. Our article on Transferring Accurate Volumes of Liquid – Dosing Peristaltic Pumps explains considerations for repeat dispensing.

Single and Multi-Channel Pumps

Single-channel systems support one fluid line, while multi-channel peristaltic pumps can run several tubing lines. Check whether channels share speed control or have independent controls, and confirm pump head compatibility before ordering. Select a configuration that suits the number of samples, flow paths and dispensing points in your workflow.

Pump Tubing and Chemical Compatibility

Choose peristaltic pump tubing by material, internal diameter, wall thickness and compatibility with the selected head. Silicone tubing and PharMed tubing offer different properties; check the manufacturer’s chemical compatibility information against the liquid, concentration and temperature involved. Confirm pressure limits, service life and any required food-contact or pharmaceutical suitability for the specific tubing grade. Inspect tubing regularly and replace it according to its condition and the manufacturer’s guidance.

Common Peristaltic Pump Applications

Laboratory peristaltic pumps support liquid transfer, sample preparation, filling and dispensing. Depending on the selected pump and tubing, applications include biotechnology processes, pharmaceutical dosing, food and beverage transfer, and industrial liquid handling. Match material suitability and process requirements to the individual product rather than assuming every pump is suitable for every application.
