All TAT Peristaltic Pumps use rotating rollers to squeeze fluid through elastomer tubing.  (Click here to see how a TAT Peristaltic Pump works.) The TAT peristaltic pump is superior to other types of pumps because the fluid that is being pumped (water, ink, acids or chemicals) never touches the pump, only the tubing.  This means that the pump will last longer, and the same pump can be used for various fluids by simply changing the tubing. As an added advantage, our pumps can pump fluids with a viscosity from water to heavy sludge and produce flow rates from 0 to 2100 gallons per hour.  We will work with each customer to match a pump to an individual application.
