1.66 x 2' MBP Bladder Pump PVC
MBPs operate on the squeeze principle whereby water, is drawn into the pump by hydrostatic pressure and contained within a fluoropolymer bladder. Pressurized air compresses the bladder to displace/lift the contained water out of the pump and through tubing that connects it to the surface. All models have a thin wall TFE fluoropolymer bladder. The plastic models are available for use in situations where stainless steel may not be the material of choice.
