TAT Engineering's pumping principle features a molded, U-shaped flexible elastomer tube, repetitively squeezed by a rotating pair of rollers, thus forcing fluid through the tube.  A flat expander within the tube is secured to the input and output hose pipes, comprising a replaceable pumping assembly giving very high flow rates and improved life over straight tubing pumps. 

Since no valves or parts come in contact with the fluid, and the elastomer tubing and hose pipes are supplied to fit each customer's specific needs, TAT pumps are compatible with most chemicals and corrosive fluids.  Tubing is available in Neoprene, Buna "N", Hypalon, Nordel or Viton.  Hose pipes come in PVC, Stainless Steel, or Teflon.  To determine which materials are right for your needs, refer to the Chemical Resistance Chart
