The Series I and II Geopump™ Peristaltic Pumps are designed for single and multi-stage pressure or vacuum pumping of liquids.The Geopump is ideally suited for field sample removal from shallow wells and all surface water sources or laboratory use.

Peristaltic Pumps are designed to remove liquid samples from shallow wells and any surface water source by vacuum or pressure pumping through tubes.

• Exceptional field durability
• Operate from 60 to a maximum of 600 RPM
• Delivery rate of 1.67 ml per revolution
• Operate to a depth of 27 feet at sea level
• Variable speed control
• Reversible flow feature for back-flushing
• Disposable and dedicated tubing means controlled costs and no decontamination issues

The Geotech Peristaltic Pumps operate by mechanical peristalsis, so the sample only comes in contact with the tubing. This allows for sample integrity as well as easy cleaning and replacement. With the optional stainless steel tubing weight, tubing can be lowered to a specific depth without curling or floating on the surface of the water. Geopumps operate from any external 12 VDC or 120 VAC power source.
