Clark Solutions' TSFR series magnetic drive rotary vane pumps handle applications such as heat exchange and process loops where many hours of operation are required. TSFR pumps are AC powered, feature four-speed selections and are rated for continuous flow to 1,000 l/h (264 gph).
TSFR pumps feature frictionless and high-efficiency electro-magnetic drives. The electronic controller for TSFR pumps provides continuous ramp speed control between 1,100 and 3,500 rpm. Motor speed can be set via dipswitches, which can be set manually or remotely or can be controlled by a proportional feedback loop.
The external feedback loop for TSFR pumps is useful for precise control of pressure or flow rate independent of variations in flow circuit conditions. The pumps also feature AISI 303 stainless-steel housings and rotors and the pumping chamber is graphite. Available pump seal elastomers include NBR, Viton and EPDM.
