Designed specifically for pulseless fluid transfer at variable flow rates. Pumps from 4-1/4 fluid ounces to 5/8 gallon (120 to 2,250 milliliters) 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 ‚Äì40 to 200°F (‚Äì40 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 PTFE. 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 inches and weight is 3-1/4 pounds.
