This SHURflo 4009 fresh water pump is the most common pump used in recreation vehicles made in Australia. It features an internal by-pass, assuring long life and top performance in all plumbing systems. The Revolution Pump is built for high flow demand, low noise and no rapid cycling. This pump is super quiet, thermally protected and can run dry without damage. Mounts in any position. This pump is a direct replacement for the Shurflo 2088 which has now been superseded.
To ensure your Shurflo Pump has valid warranty, they must be installed with a filter.
* If a strainer is not installed prior to the pump then the warranty is not valid.
* Installation of a check valve between the pump and the water (if applicable) will prevent damages to the pump and the city water entry due to high pressure spikes from the water heater.
* Restrictions in a plumbing system may cause the pump to rapid cycle (ON/OFF within 2 sec.) during low demands. Cycling should be minimized to prevent pulsating flow and to achieve maximum pump life. To determine if adjustment if necessary, turn tap on to lower than average flow of water. The pump should cycle, but its "OFF time" must be 2 seconds or longer. If the cycling is correct, leave well enough alone. If the Pump is cycling rapidly increase the setting by turning the screw clockwise (1/2 TURN to 3/4 TURN MAX.) until the pump operates for 1 second with at least 2 seconds "OFF time". If cycling cannot be minimized consider removing plumbing restrictions or simply install a SUURFLO Accumulator.
* Use flexible high-pressure hose on the pump inlet and outlet (such as SHURFLO Kit 94-591-01)
* The pump inlet- and putlet- ports and strainer should not be connected to rigid plastic pipe.
* Sealers and Teflon tape may act as a lubricant causing cracked housing or stripped threads due to over tighting. Sealer may enter the pump inhibiting valve action, causing no prime or shut-off. A failure due to foreign debris is not covered under warranty.
Notes: Please read the usermanual carefully before installation, otherwise warranty will be void.
