Model 464 Electronic Control Unit
(125 psi and 250 psi Models)
Pump Controllers
The 464 Electronic Pump Control Unit is available in 125 or 250 psi versions. It uses 4 AA alkaline batteries that last up to 100 hours of normal use. You can also operate these Controllers manually if your batteries run out in the field, using only a compressed gas source. It has automatic preset sample modes from low through high flow settings. In addition, up to 99 user-created flow rates can be saved in FRAM memory. The Controller allows faster purge rates and precise low-flow control to ensure a representative sample at 100 ml/min or less when sampling for VOCs.
These convenient Controllers are rugged, dependable, and suitable for all environments. Quick-connect fittings allow instant attachment to dedicated well caps, portable reel units, and an air compressor or compressed gas source.
12 Volt Compressor
12V Oil-Less Air Compressor
The Solinst 12 Volt Compressor is lightweight (21 lbs (9.5 kg), compact, and ideal for field use, especially low-flow applications of less than 30 m (100 ft) depths.
The compressor uses a 12-volt DC power source, such as a car or truck battery, and comes with alligator clips. It operates at up to 150 psi and is equipped with a 2 US gallon (7.6 L) air tank rated to 175 psi.

Filters and Packers
Stainless Steel Bladder Pumps Pumps come complete with a 50 mesh intake filter over the sample inlet, while PVC Bladder Pumps come with a polyethylene screen. These filters are straightforward to replace. If required, Solinst also supplies Model 860 Disposable In-line Filters for use on the sample discharge tube. They are adaptable to fit many sizes of tubing. (See Model 860 Disposable In-line Filter Data Sheet)
Model 800 Low-Pressure Packers can be used with Solinst Bladder Pumps to minimize purge times by reducing purge volumes. This reduces the cost of water disposal and labour. Packers are available in single point or straddle packer designs and in sizes to fit 2" (50 mm) to 5" (127 mm) diameter wells. (See Model 800 Low Pressure Packer Data Sheet)
