Variable Flow Peristaltic Pumps

High-performance–low cost!

Low-cost, self-priming peristaltic pump precisely meters dosing and fluid transfer. Variable speed motor yields flow rates of 0.03 mL/ min to 85 mL/ min; reverse switch changes direction of flow. Accepts 5 tubing sizes for excellent resolution over the entire flow range.

Three-roller design reduces flow pulsation, prevents siphoning, and eliminates check valves. Pumps liquids and gases–dry operation will not harm the pump. Purge/ prime switch allows high-speed emptying/ filling.

Pump includes silicone tubing ( sizes 1/ 50 ” , 1/ 16 ” , 3/ 32 ” , 3/ 16 ” , and 1/ 4 ” I.D.) , polypropylene fittings/ nipples, auxiliary battery connector ( battery not included) and cord with plug. Compact ABS plastic case measures 6 5/ 8 x 4 3/ 4 x 4 1/ 2 ” . Operates on 115 V, 60 Hz or 9 V battery ( not supplied) .
