RP-Q Series Miniature Peristaltic Pump
DC Power, Discharge Flowrates to 3.0 ml/min
Model RP-Q series peristaltic pump is uniquely compact and designed for intermittent duty where 500 hours is considered to be adequate life for the pump.
RP-Q pumps employ unique ring technology whereby a ring affixed to a motorized eccentric acts on the tubing instead of conventional rollers. The result is less stress on the tubing and longer tube life. See below illustration.
The pumps consume very little power (<0.36 W) and operates on 3 VDC. They can be battery operated.
Two models (QII & QIII) feature a field replaceable pump head.
