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.

Peristaltic Pump Design

The Solinst Peristaltic Pump features a clear pump head that allows quick, convenient inspection of the pump head tubing before and during operation. The pump head cover is easy to remove for cleaning or replacing the tubing. The pump head tubing guides are designed to keep the tubing in place during sampling, no extra tubing clamps required.

The Peristaltic Pump is compact and lightweight. A handle and one convenient control on the top of the pump make it perfect for fieldwork.

The Solinst Peristaltic Pump has no vents, grates or openings. The metal case is extremely robust and water resistant. This makes the Peristaltic Pump simple to maintain and repair.

Power Source & Motor

A 12 ft. (4 m) power cord uses alligator clips to connect to almost any 12 volt DC power source that can supply at least 3–5 amps at maximum draw (such as auto, marine or small gel cell battery). The pump may be connected directly to your vehicle battery.

The variable speed motor is reversible, has an easy-to-reset circuit breaker (no fuse to replace), and has reverse polarity protection to prevent damage to the pump.

Peristaltic Pump Tubing

The standard pump tubing is 5/8" OD (16 mm) medical grade silicone, which attaches easily to 1/2" OD (13 mm) downhole tubing. An adaptor kit, which allows the use of 3/8" OD (10 mm) tubing, provides lower sampling rates. This tubing attaches easily to 1/4" OD (6 mm) down-hole tubing.

To provide high sample integrity, the sample comes in contact only with the tubing. Replacing the tubing between locations avoids the possibility of cross-contamination. To reduce lengthy decontamination procedures, simply dedicate the inexpensive down-hole tubing.

Sampling Rates

The Model 410 Peristaltic Pump has variable pumping rates, using two different sizes of silicone pump head tubing. With the standard 5/8" OD (16 mm) tubing it delivers from 120 ml/min to almost 3.5 L/min.

The 3/8" OD (10 mm) tubing adaptor kit allows a sample rate as low as 40 ml/min and up to 900 ml/min. This low rate is ideal for low-flow sampling and the filling of small sample bottles.

The Peristaltic Pump's reverse action is ideal for back flushing when using the Drive-Point Profiler
