Masterflex pumps and accessories

Engineered for long life, Masterflex® peristaltic pump systems provide superior accuracy and repeatability and ensure optimal performance when used with the proper tubing. These pumps offer the latest technology including MasterflexLive® cloud-enabled connectivity, easy control and tubing changes, and the low-maintenance and cost-effectiveness of peristaltic pumps.

Choose the right pump for your application!

Each pump system is divided into three parts: pump head, drive, and tubing. The pump head consists of the rotor and housing; the drive creates the force needed to move the rotor; and the tubing acts as the pump chamber. These three parts pump fluid by following these steps:

  1. The tubing is placed into the tubing bed—between the rotor and housing—where it is occluded (squeezed).
  2. The rollers on the rotor move across the tubing, pushing the fluid. The tubing behind the rollers recovers its shape, creates a vacuum, and draws fluid in behind it.
  3. A "pillow" of fluid is formed between the rollers. This is specific to the ID of the tubing and the geometry of the rotor. Flow rate is determined by multiplying speed by the size of the pillow. This pillow stays fairly constant except with very viscous fluids.
