Designed specifically for pulseless fluid transfer at variable flow rates. Pumps from 4-1/4 ounces to 5/8 gallons (120 ml to 2-1/4 liters) 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, Viton, and Dupont Teflon®. Pump has a purge/prime switch for high-speed emptying/filling. It also reverses for ease in draining tubing. May be used with up to 120 feet of tubing for remote sampling.

Pump comes ready to use with 115 VAC UL-rated wall power supply. Packaged in a chemical-resistant ABS plastic case. Size is 8" x 4-3/4" x 4-1/2" and weight is 3-7/8 pounds.
