Simple to Operate Pump Controller
The Solinst Model 464 Electronic Control Unit is used to set the pressure and regulate the supply of drive gas or compressed air that is required to operate Solinst Pneumatic Pumps. Drive (pressure) and vent periods are cycled to provide water flow from the groundwater sampling pumps.
The Model 464 Electronic Pump Control Unit is fully automatic with preset sample modes from low through high flow sampling. 125 psi and 250 psi versions are available. Use with a Solinst Model 407 Bladder Pump or 408 Double Valve Pump for effective VOC and low-flow groundwater sampling. Quick-connect fittings make it easy to attach the drive and supply lines to the Electronic Control Unit and pump setup.
- Ideal for use with Bladder Pumps
- 99 customizable sampling presets
- Use in automatic or manual mode

Bladder Pumps
Bladders ensure no air/water contact during operation, providing representative groundwater samples and excellent VOC sample results. Bladder Pumps are also EPA approved for low flow groundwater sampling.
Double Valve Pumps
Double Valve Pumps are positive displacement gas drive pumps that provide high and low flow groundwater sampling, without the use of a bladder. Representative groundwater samples are produced, ideal when sampling for PFAS.
415 12V Submersible Pump
The Solinst 12V Submersible Pump provides an efficient means of purging and obtaining groundwater samples from 2" OD monitoring wells. The compact pump can sample from depths of 36.5 m (120 ft) below ground surface, and is easy to adjust the flow rates up to 13.5 L/min (3.6 US gpm) in shallower applications.
