Boat pump FB-3000 series

bilgeengine coolingfire fighting system

Whenever you need greater strength or service from a pump, use an extra heavy duty flexible impeller pump with separate bearing housing and mechanical seal for less wear and longer life. These pumps cover the entire range of marine applications and may be used as cooling water pumps, bilge pumps, deck wash pumps, emergency and fire fighting pumps, etc. Features FxB-3xxx = Flexible Impeller Pump, Bronze body, 3 = Pedestal mounted with double ball bearings and mechanical seal TSS - The Space Saver - horizontal flanges in a space saving design VF - Vertical Flanges Available in sizes from ¾" to 2 ½" (13 L/min to 625 L/min) Wear parts are easily replaceable and service kits are available for all standard models Connections BSP or NPT Vacuum switch as extra accessory Theory Of Operation Flexible Impellers - Operating Principle A vacuum is created as the flexible impeller vanes straighten upon leaving the cam, drawing liquid into the pump. The rotating impeller carries liquid from the inlet to the outlet port. As a consequence of their design, flexible impeller pumps can pass fairly large solids. When the flexible impeller vanes regain contact with the cam, they bend and the liquid is discharged from the pump in a uniform flow. Liquids can be pumped in the opposite direction by reversing the rotation of the pump.
