Pumps and Sampler
Peristaltic Pumps are designed for single and multi-stage pressure or vacuum pumping of liquids
for the field or laboratory. Constructed of heavy-duty anodized aluminum, these units are truly
rugged pieces of equipment. Well suited for sample removal from shallow wells and all surface
water sources. Operating by mechanical peristalsis, the sample only comes in contact with the
tubing to assure there is no cross contamination. The Series I has one pumping station which
has a variable speed from 60 to 350 rpm. The Series II has two pumping stations, 60 to 600 rpm.
Power AC only, DC only or AC/DC combination.

Bladder & Peristaltic Pumps
The pneumatic Mini Bladder Pumps are designed to obtain a representative ground water sample
with the assistance of a controller to provide variable flow rates. The controller allows the user to
match the pumping rate to the well recharge rate, limiting the stress on the formation. With the
small volume per cycle, the fluid velocity at the pump inlet is substantially reduced, making the
pumps ideal for low flow sampling. The 1.66 in diameter pump will produce flow rates up to 2
gpm. The bottom inlet of the pump is positioned at the desired sampling point, generally at the
mid section of the well screen. The inner Teflon
®
bladder will fill with fluid based on the submer-
gence of the pump. The annular space is pressurized using the controller and the liquid is gently
lifted to surface. All pumps can be supplied contaminant free.
Dedicated assemblies can be supplied to reduce cross contamination, well disturbance and facili-
tate installation. The pump, tubing and well cap assemblies are plastic bagged and each assem-
bly is identified with your well ID number and the well depth.
