Waterra Inertial Pumps systems are available in four performance ranges: Standard Flow, High Flow, Low Flow and Micro Flow.
The performance of each flow range is defined by its tubing diameter -- the larger the tubing the greater the flow rate and depth capability.
The WaTerra Hand Lever Pump is an inexpensive way to sample wells without an extra power source. It mounts on the top of the well casing to provide mechanical leverage and support for the manual up/down pumping action. An easy adjustment for centering the tubing in the well and quick release clamps give efficient operation. A fixed support for the discharge tubing facilitates sample bottle filling and flow rate measurement. The handle is easily carried from well to well. It does not require decontamination, as no part of the handle comes into contact with the pumped water.
Teflon Lined Low-Density Polyethylene Tubing combines the benefits of Teflon with the low cost and pliability of Low-Density Polyethylene Tubing.
Perfect for Air Sampling where full Teflon tubing is too rigid or where cost is a factor

The Grundfos Redi-Flo2® electrical submersible pump provides smooth, uninterrupted water flow during ground water sampling to depths down to 280 feet (85m). Both high flow rates needed for purging and low flows recommended for sampling are achieved with the same pump.
The Redi-Flo Variable Frequency Drive (VFD) is designed to operate and protect the Redi-Flo2® and the RediFlo4™ Variable Performance Pumps. With the push of a button, an operator can precisely control the discharge flow rate from the pump from 50 GPM (189 LPM) to 100 milliliters per minute, to depths down to 524 feet (160m).
Designed for field use, the reversible flow Peristaltic Pump from Solinst is ideal for vapor sampling or water sampling from shallow wells and surface water. It can be used for vacuum pumping and for pressure delivery of liquids or gases.
The mechanical peristaltic operation uses rotating rollers to depress the silicone tubing, creating a vacuum, which displaces any fluid or gas in the chosen direction. It is effective to depths up to the suction lift limit, which varies with elevation, and can be as much as 33 ft. or 10 m at sea level.
