Bladder pump (stainless steel)

This stainless steel bladder pump provides consistent, accurate, reliable groundwater samples in all applications. Ensuring no air/water contact during operation, pumps are ideal for VOC (Volatile Organic Compounds) sampling. Inexpensive polyethylene bladders are also available. This pump is effective at any angle, to depths of 500 ft (150 m), and is ideal for low flow sampling. Available in diameters of 1” and 1.66”.

An electronic pump control unit (PCU-464) is also available in 125 or 250 psi versions. The pump control unit allows faster purge rates and precise low flow control to ensure a representative sample at 100 ml/min or less when sampling for VOCs. It uses 4 AA alkaline batteries that last up to 100 hours of normal use. This controller can also be operated manually, using only a compressed gas source. Programmable by the user. Very effective for outside applications.
