Jabsco 50880 Series Self-Priming Diaphragm Bilge And Shower Pump

The Jabsco 50880 is a self-priming diaphragm pump for shower drains, auxiliary bilge duties and general water transfer, with 12V and 24V models and flow up to 16.3 LPM.

Its diaphragm design can run dry without damage and moves water containing small debris without requiring an inline filter in many drainage applications. The pump is non-automatic and must be controlled by a suitable switch or level-control system.
