Designed specifically for pulseless fluid transfer at variable flow rates. Pumps from 120 mL to 2.2 L (4.2 oz to 0.6 gal.) per minute. Pumps fluids with a viscosity to 200 centipoises. Suction lift is 10 feet wet, 4 inches dry. May be used with fluid temperatures from -40 to 200°F (-40 to 93°C). Barbed inlet/outlet ports use any type of tubing with an inside diameter (nominal 3/16 inches). Direct-drive engineering provides maximum motor power to the pump. "Continuous-sweep" variable control provides precise, seamless speed control. The chemical-resistant, wetted parts are Dupont Delrin*, 304 stainless steel, Buna N, and Dupont Teflon. Pump has a purge/prime switch for high-speed emptying/filling. It also reverses for ease in draining tubing. Packaged in a chemical-resistant ABS plastic case. Size is 8 x 4-3/4 x 4-1/2 inches. 110V
