Use this self-priming diaphragm pump as a shower or galley waste pump. These 3.7gpm waste pump and strainer systems from Whale Pumps offer easy access with a remote mount to effectively pump shower waste, such as hair and shower products. The large 3/4" inlet and outlet valves are cut at 45 angles to minimize flow restriction while the ports rotate to the position you need to facilitate hose connections. It mounts vertically or horizontally making installation a snap. It can run dry for extended periods without burnout and boasts a large diaphragm that generates up to 13' of lift. And because there is no filter, you wont have to worry about cleaning blocks and clogs.
