Whale Gulper 220 Shower Drain & Grey Waste Pump – 12V (BP1552)
A quiet, heavy-duty diaphragm pump purpose-built for draining marine shower sumps and grey waste systems. Unlike centrifugal pumps, the Gulper 220’s large diaphragm design handles shower water, soap residue, and small debris without a strainer or filter — one less maintenance item to worry about and one less failure point in the system.
The pump runs dry without damage, so it won’t burn out if the sump empties before the pump shuts off. Self-priming to 10 feet means it can be mounted above the wet area, keeping the motor out of standing water. The multi-directional pump head gives you flexibility to orient the unit however your installation requires.
