Cole-Parmer offers a range of tubing pumps suitable for dispensing, metering and general transfer applications. Our 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).
Tubing 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 tubing 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 tubing pump offers easy maintenance and reduced down time compared to other pumping technologies.
Tubing 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 tubing 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 tubing pump solution.

Advantages for tubing pumps
- The only part of a tubing 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 tubing pumps for excellent compatibility with a variety of liquids
- Self priming - our tubing 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 tubing pump ideal for handling cells and large proteins, as the pumping action will not damage the content
- The fluid does not contact the tubing 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 tubing pump is non-siphoning which means that they prevent back flow into the system. This promotes accuracy during dispensing
