With a capacity of up to <strong>31 litres per minute (500 gallons per hour)<\/strong>, it\u2019s perfect for small to medium-sized vessels.<\/p>\n<p>Featuring an advanced computerised sensor, this pump checks for water every 2.5 minutes, running for only half a second if none is detected. This ensures minimal battery draw, consuming just 0.20 amps per day when on standby. The pump also features built-in backflow prevention with a check valve, a vented body to prevent air locking, and thermal cut-off for added safety.<\/p>\n<p>Constructed from durable thermoplastic with an integral strainer, the pump is robust and easy to clean. It operates on <strong>12V DC<\/strong>, drawing just 1.6 amps, and includes a threaded 19mm (3\/4\u201d) discharge port for seamless installation.<\/p>\n<p>Rule Industries has been a trusted name in bilge pump technology for over 50 years.
