The self-priming design has no seals to leak or valves to clog, and can run dry for extended periods without damage. Compact in size with integral handle, it fits on drum lids without protruding, and has sufficient lift characteristics to operate from the floor, skid, or stand. Only two non-metallic parts are in contact fluid: a thermoplastic body block, and an elastomeric flexible liner that can be easily replaced in the field.

The rigid body block is of solid polypropylene, UHMW polyethylene, or PTFE, and the molded flexible liner of natural rubber or elastomer plasstics, eliminating corrosion or contamination associated with metal pumps. The pump is suitable for flows from 1.25 to 151 litres/h and pressures up to 310 kPa.
