Blatypus Pump

Blatypus Pump has no internal bladder, but functions like a bladder pump.

The pump eliminates purging and sampling problems associated with tearing and leaking bladders as well as limited lift capacity issues with traditional bladder pumps.

With durable fittings, sturdy design, and low cost, the Blatypus Pump is the next generation in low-flow submersible pump technology suitably designed for 20ft-3000ft bgs applications.
