Integrate a dependable peristaltic pump to achieve exact fluid handling across your processing applications. Forming a core segment of our extensive Laboratory catalogue, these versatile positive displacement solutions isolate media entirely from mechanical components. We supply premium configurations from Cole-Parmer alongside industrial-grade drives from Masterflex. By integrating supplementary dispensing equipment from Sigma and Gilson, we ensure you have access to continuous tubing solutions for stringent batch testing or commercial manufacturing.
Peristaltic Pumps
Enhancing Process Control with an Industrial Peristaltic Pump
Our curated collection of peristaltic pumps delivers high-capacity performance and operational flexibility for technical environments:
- Zero Cross-Contamination: Utilise Cole-Parmer units to confine abrasive or sensitive liquids strictly within the hose path, protecting both the instrument and your valuable biological samples.
- Heavy-Duty Material Handling: Implement Masterflex hardware designed specifically to process viscous slurries or shear-sensitive polymers, directly addressing the limitations of standard liquid handling devices.
- Customised Dosing Architecture: Assemble a highly accurate dispensing circuit by pairing modular drives with specialised tubing categories for reliable volumetric repeatability.
How to Choose the Right Peristaltic Pump
Selecting the correct peristaltic pump for your facility requires evaluating several technical parameters:
- Fluid Viscosity and Shear Sensitivity: Analyse the physical properties of your medium to ensure the rotational action of the rollers will not degrade delicate cellular structures or complex emulsions.
- Pumping Pressure Requirements: Confirm that the selected wall thickness of your tubing and the motor torque can sustain the required continuous operating pressure without rupturing.
- Environmental Operating Conditions: Decide if your processing area necessitates washdown-capable stainless steel housings or specialised explosion-proof motors for hazardous locations.
Expand Your Liquid Handling Capabilities
Versatile equipment is essential for comprehensive facility management. To further optimise your workspace, we recommend exploring these related categories:
- Laboratory general purpose tubing: Procure the highly specialised internal lines required to withstand constant compression from positive displacement rollers.
- Laboratory mixers: Prepare homogeneous suspensions and complex chemical blends prior to automated dispensing through your pump network.

Frequently Asked Questions
How does a peristaltic pump work for viscous fluid transfer?
The system operates using alternating compression and relaxation of a flexible hose. Rotational rollers squeeze the tube to push liquid forward, while the immediate restoration of the tube shape generates a powerful vacuum that continuously draws in thick or heavy materials.
