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.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen 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.\u003c\/p\u003e\n\u003cp\u003eIt'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.\u003c\/p\u003e\n\u003cp\u003eWhale backs the Gusher 30 with a five-year warranty.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTwin fully enclosed diaphragms pump on both strokes, up to 117 liters\/min (31 US gallons)\u003c\/li\u003e\n  \u003cli\u003eThru-deck mount keeps the pump body below deck with the handwheel up top\u003c\/li\u003e\n  \u003cli\u003eMarine-grade LM6 aluminium alloy body, epoxy coated for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHandles oily bilge water and light debris without clogging\u003c\/li\u003e\n  \u003cli\u003e38mm (1-1\/2 in) hose connection, backed by a 5-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Whale reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow much water does the Gusher 30 move?\u003c\/summary\u003e\n    \u003cp\u003eAt 70 strokes a minute it clears 111 liters (29 US gallons), and it peaks at 117 liters (31 US gallons).
