Jabsco Filterless Bilger - Sink - Shower Drain Pump

The Jabsco Filterless Bilger Sink Shower Drain Pump (Model 50880-1000) is a single diaphragm marine pump engineered specifically for drainage applications aboard vessels of all sizes. Built to handle sink, shower, and bilge drain duty, this pump delivers reliable water removal without the maintenance burden of filter systems, making it an essential component for cruising sailboats, fishing vessels, and offshore motorboats where operational simplicity is paramount.

This pump achieves a nominal flow rate of 16 liters per minute (4.2 US gallons per minute), sufficient for continuous drainage of shower and sink water in typical marine installations. The self-priming capability extends up to 3 meters (10 feet) of vertical lift, allowing flexible mounting locations below the waterline or in engine compartments without requiring manual priming before operation. The filterless design eliminates clogging concerns from sediment or debris, while the compact footprint and dry-running capability provide installation flexibility in tight below-deck spaces. Built to ISO 8846 marine standards for ignition protection and ISO 8849 specifications for marine bilge pumps, this unit meets rigorous USCG regulatory requirements for marine electrical equipment.

Serious recreational anglers, liveaboard cruisers, and commercial fishing operations benefit from this pump's rugged single diaphragm design and straightforward operation. Weekend boaters appreciate the elimination of filter maintenance, while offshore captains rely on its ability to handle sustained drainage demands. The pump solves the recurring problem of galley and head water accumulation—a persistent concern in any marine environment where moisture intrusion and standing water can lead to mold, odor, and structural degradation.

Jabsco's Filterless Bilger represents the practical choice for vessel owners seeking dependable drain management without the complexity of serviced filters. Its proven architecture, compliance with international marine standards, and ability to operate reliably in salt-water environments make it the logical upgrade or replacement for aging or undersized drainage systems.
