Rule LP900S
Our latest automatic pump design, the LoPro allows for pumping out of tight spaces and shallower bilges. The LP900S model uses a unique double system for sensing water, to ensure that the pump only ever operates when water is present, and switches off efficiently when it’s not. If water is sensed, the pump will spin the impeller as a double check. If water is confirmed, the pump will run to empty the bilges. The pump body rotates to allow discharge in any direction. A selection of straight and 90 degree ports, and a non-return valve for use with straight ports, are supplied.
