Little Giant # 587106 7-MD-CK Magnetic Drive Centrifugal Pump

The Little Giant 587106 is a 7-MD-CK Magnetic Drive Centrifugal Pump, replacement Pump End only, no motor, with a 1-1/2 inch FNPT inlet port by 1 inch MNPT outlet port, replacement pump end only without a Motor. The patented Little Giant magnetic drive pump design consists of a cylindrical drive magnet attached to the motor shaft, which rotates around a chemical resistant plastic separator housing. Inside this housing is a magnet completely encapsulated in stainless steel, and fixed to the impeller. The impeller assembly is free to rotate on a spindle that is supported at both ends. The spindle is held captive and does not turn. Front and rear thrust washers are utilized as wear bearings. The washers are held captive and do not revolve. This prevents wear on the shaft. With the magnetic coupling the motor drives the impeller. This coupling eliminates the conventional shaft seal and its possibility of leakage. These models utilize a carbon bushing between the impeller and spindle. The use of this carbon bushing will allow these pumps (SC and HC) to run dry (without fluid) for up to 8 hours with no apparent detrimental harm to pump. All wetted parts can be serviced by removing (6) bolts which hold the volute to the housing. The pump head components can easily be replaced in the field if necessary. The pump's volute and backplate are made from carbon-filled Kynar; its impeller, carbon-filled Kynar with carbon-filled Teflon bushing; its shaft and thrust washers, ceramic; and its O-Ring, Viton. This pump is designed specifically and exclusively for use in non-submersible, in-line applications. It uses ball bearings, a conduit box, and a thermally protected, totally enclosed, fan-cooled, capacitor start motor. It can pump liquids with a specific gravity up to 1.1. It can operate in a maximum ambient air temperature of 77 F, and can pump fluids with a maximum temperature of 200 F
