With an Electro-Magnetic Clutch you will have pumping power whenever needed, at a push of a button, without being at the pump. Combined with a vacuum switch (recommended for bilge pump application), the clutch will automatically disengage whenever the pump starts priming air, thereby preventing dry running and pump damage. Features FxB-5xxx = Flexible Impeller Pump, Bronze body, 5 = Pedestal mounted with double ball bearings and mechanical seal, magnetic clutch operated TSS - The Space Saver - horizontal flanges in a space saving design VF - Vertical Flanges Automatically controlled pumps are available in sizes from 1" to 2½" (20 L/min to 625 L/min), with clutches in 12 or 24 volts. Wear parts are easily replaceable and service kits are available for all standard models. Vacuum Switch as extra accessory Note! Clutch to be ordered separately 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.
