The Geopump™ Series I and II Peristaltic Pumps
were designed for single and multi-stage pressure or
vacuum pumping of liquids for field or laboratory use.
Because they operate to a depth of 27 feet at sea level,
they are ideally suited for sample removal from shallow
wells and all surface water sources. They operate by
mechanical peristalsis, so the sample comes in contact
only 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.
The Peristaltic Pumps which measure 3 1/2" x 8" x 8"
operate off of any external 12 VDC or 120 VAC power
source. The AC cord is 8 feet in length. The DC power
cord is 15 feet long, has a cigarette lighter to battery
clip adapter. All of these units have variable speed
control and (depending upon model), operate from 60 to a
maximum of 600 RPM with a liquid delivery rate of 1.67
ml per revolution. All peristaltic pumps have the
reversible flow feature that works in conjunction with
plate-type Back flushing Membrane Filter Holders, or the
disposable filters. The reversible flow feature extends
the life of the filter membrane in both types of filters
under heavy sediment-laden waters. Both filtering
systems are compact and very portable.
Series I Peristaltic Pumps have one pumping station
which can also be piggy-backed for multi-station
pumping. They are variable speed from 60 RPM to 350 RPM.
Series II Peristaltic Pumps have two pumping stations
which can also be piggy-backed. The first pumping
station is rated at 30 RPM to 300 RPM and the second
station at 60 RPM to 600 RPM. Each pumping station works
in conjunction with the other.
