With powerful motors, the Masterflex B/T Fixed-Speed pumps transfer viscous or shear-sensitive materialsand offer flow rates up to 42 LPM (11.1 GPM) when used with B/T pump tubing. The durable construction of these pumps ensures a long service life with minimal maintenance. The 746 W (1 hp) reversible motor enables users to pump fluids in either direction and easily prime or purge tubing. The occlusion mechanism slides the tubing bed out of the way for easy tube loading and improved occlusion of the tubing when the pump head closes. The tubing retention mechanism holds the tubing firmly in place to allow for a simple loading process. New tubing formulations provide longer tubing life.
