Variable-Flow Pumps

Deliver Fine Resolution with a Wide Flow Range

Transferring liquids? Dosing liquids? These compact, bi-directional pumps offer outstanding flow control and flexibility. Fluid contacts only the tubing for contamination-free pumping. Ideal for use with food, pharmaceutical and other critical solutions and gases.
Specifications: Self-priming, peristaltic pumps feature a purge/prime switch for high-speed emptying and filling. Pumps reverse at the touch of a switch for easy draining of tubes. Pumping dry (air or gas) will not harm pumps. All models include five sizes of autoclavable silicone tubing (1/32", 1/16", 3/32", 3/16" and 1/4" I.D.), polypropylene fittings/nipples, a 115V AC, UL-rated power supply and an accessory battery connector (battery not included). Tubing stands up to fluid temperatures from -80 to 500°F (-62 to 260°C). Pumps measure 4-3/4"H x 6-5/8"W x 4-1/2"D.
