The RULE General Purpose End Suction Centrifugal Pump delivers 3700-3800 GPH (approx. 14010-14380 LPH) for high-flow, low-pressure marine applications such as washdown and livewell circulation. The pump is designed with 1-1/2" (38mm) hose barb inlet and discharge ports and heavy-duty plastic construction for use on commercial or pleasure boats. It must be mounted below the waterline and is not self-priming—it delivers lots of water but at low pressure. Dimensions noted in variants include a height of 133 mm (5-1/4 inches) and width of 216 mm (8-1/2 inches). Offered in DC voltage options including 12V and 24V.
