Importance of Peristaltic Pumps

Peristaltic Pumps are an economical way to move a wide variety of fluids. They can be used for many different applications including, medical, laboratory, food, hazardous chemical handling, and water & wastewater processing metering. Peristaltic Pumps use a hose (or tube) of hard, chemical-resistant material to create a seal between itself and the pumped liquid. When the rotor of the pump turns, rollers or shoes on the rotor compress the tube, trapping a body of fluid between them and forcing it toward the pump outlet. The displaced fluid then moves back toward the pump inlet, completing one cycle of the pumping action. The pump can run continuously or be indexed through partial increments to achieve smaller volumes of fluid with each index.

The peristaltic pumps we offer are designed with specific tubing materials to match the requirements of the specific pumping application and fluid. These tubes are molded to be as durable and long-lasting as possible for their intended use and can be easily identified at the hose connections with easy-to-read color indicators. Changing the tube type requires only the removal of a plug at the hose end and insertion of the new tubing, saving time and money.

A peristaltic pump's performance is dependent on the ability to apply and sustain a controlled amount of pressure to the tubing over a long period of time. When the pressure applied to the tubing is not consistent, performance will diminish over time as the hose experiences repeated compression and decompression. Thermoline offer a variety of solutions to help ensure that the tube is adequately pressurized throughout its operation and that your pump's performance remains stable.

Thermoline peristaltic pumps are available in a number of sizes to suit your pumping application and fluid type. In addition, they can be configured with a variety of control options including manual or automatic shut off, a timer, an external flow sensor, and a digital display. Our peristaltic pumps are also available in different voltages to accommodate your preferred power supply or operating environment.

We also offer a range of accessories to improve your pump's performance, from air and fluid separators to hose couplings. These accessories can help to eliminate bubbles and air from the system, prevent leaking hose ends, and reduce wear on the hose.
