At the core is a 12-pole motor with double ball bearings for extended service life, paired with a stainless steel shaft and liquid cooling to keep the motor running cool during extended operation. The impeller is designed to maximize flow and head, delivering 4000 GPH in a straight discharge and 2600 GPH at a 1.0 meter head. A universal base plate gives installers a choice between two different ports, simplifying mounting in tight bilge spaces. The pump housing uses high impact ABS plastic together with a mechanical shaft seal and a unique threaded port design for a durable, leak resistant build. A removable check valve is included to prevent backflow once installed. The 40004 draws 15 amps and is recommended for use with a 25A fuse, with a 16 gauge wire run of 6 feet supplied. Connections accommodate 1-1\/2 inch and 2 inch hose sizes. For automatic operation, this bilge pump can be combined with an electronic float switch or an Ultima style switch, letting it turn on and off based on bilge water level without manual intervention.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson
