Cole-Parmer offers a range of peristaltic pumps suitable for dispensing, metering and general transfer applications. Our peristaltic tubing pumps offer flow rates as low as 0.0007 mL/min to 45 LPM and are able to generate pressures up to 8.6 bar (125 psi).

Peristaltic pumps confine the media to the tubing providing you with a pump that cannot contaminate the fluid and the fluid cannot contaminate your pump. This contamination free pumping makes peristaltic pumps great for use in high purity application including the transfer or dosing of chemicals and additives in food, pharmaceutical and semiconductor applications. In addition as the media is confined to the tubing a peristaltic pump offers easy maintenance and reduced down time compared to other pumping technologies.

Peristaltic pumps use flexible tubing to run through rollers in the pump head. As fluid goes through the pump head, packets of fluids are formed. Flow rate is determined by the size of the packets and the speed of the rollers turning. By controlling the size of the tubing and the speed of the pump head accurate metering of the media can be achieved.

Cole-Parmer offer peristaltic pumps suitable for use in labs, pilot plants, process and OEM applications. From low cost fixed speed pumps to advanced controlled models suitable for critical metering and dispensing applications Cole-Parmer is able to offer a peristaltic pump solution.

Advantages for peristaltic pumps

• The only part of a peristaltic pump that comes in contact with the liquid is the tubing. This maintains the sterility of fluid and the pump
• Cole-Parmer offers over 20 tubing formulations and sizes for their peristaltic pumps for excellent compatibility with a variety of liquids
• Self priming - our peristaltic pump will draw fluid into the tubing when starting dry, up to 8.8 m suction lift. Other pumps require user to fill pump and suction line with fluid before use which can be inconvenient and also create potential for hazardous spills or contamination
• Gentle pumping action - low shear - makes a peristaltic pump ideal for handling cells and large proteins, as the pumping action will not damage the content
• The fluid does not contact the peristaltic pump so there are no parts to clean such as valves, diaphragms, seals etc. All you have to do is clean or replace the tubing. This easy tubing replacement means reduced maintenance times
• A peristaltic pump is non-siphoning which means that they prevent back flow into the system. This promotes accuracy during dispensing
