Solinst 464 pump control unit is ideal for controlling bladder pumps and double valve pumps as part of a low flow sampling equipment setup. The 464 is also very effective for VOC (Volatile Organic Compounds).
Powered by 4 AA alkaline batteries, the 464 Electronic Pump Control Unit is able to operate for up to 100 hours. If batteries drain in the field, the pump-control unit can be operated manually from a source of compressed gas.
The 464 Electronic Pump Control Unit is available in 125 psi and 250 psi versions, both featuring automatic flow rates. Additionally, 99 custom-made flow rates can be saved in the control unit's FRAM memory. Samples can be collected at up to 100 ml per minute, and when sampling for a Volatile Organic Compound (VOC), the unit speeds its purge rates and allows for precise low-flow control to ensure that representative samples are collected.
Well suited for all environments, these pump-control units are robust and reliable. Quick-connect fittings make it easy to link dedicated well caps, portable reel units, and sources of compressed gas to the 464.
The 464 regulates the amount of compressed gas supplied to pneumatic pumps, such as bladder and double-valve pumps. To generate better water flow, drive and vent periods are cycled. During drive periods, water is forced into the sample tubing with pressure from compressed gas. During vent periods, water flows back into the pump. The repetition of this cycle can be controlled manually or automatically.
