Whale Gusher 30 Manual Thru-Deck Mount Bilge Pump — Product description

The Whale Gusher 30 is the biggest manual bilge pump Whale builds, and it moves serious water. A twin-diaphragm design pushes up to 117 liters a minute (31 US gallons) on both the push and pull stroke, and it handles oily bilge water without complaint. Thru-deck mount, epoxy-coated aluminium body, five-year warranty.

When you need to clear a lot of water by hand, the Whale Gusher 30 is the pump that gets it done. It's the largest-capacity manual bilge pump in the Whale range, and the numbers back that up. Twin fully enclosed diaphragms pump on both the to and fro stroke, so every pull of the handle actually moves water. At a steady 70 strokes a minute you're clearing 111 liters (29 US gallons), and it'll peak at 117 liters (31 US gallons) when you really lean into it.

It's built to sit through the deck, with the pump body below and the handwheel up top where you can reach it. The body is marine-grade LM6 aluminium alloy, epoxy coated to fight corrosion, with a neoprene diaphragm and stainless steel fasteners. And because it's a diaphragm pump, it doesn't care about a little oil or debris in the bilge water. It just keeps moving it.

Whale backs the Gusher 30 with a five-year warranty.
