Goulds Pump 15BF2NBK3 Centrifugal Pump and motor

The Goulds 15BF2NBK3 is a Centrifugal Pump and Motor, 3656M Series (4 x 6 - 13), Cast Iron Bronze fitted construction (Cast Iron Casing - Bronze Impeller), with a 9.88 Inch Silicon-Brass Impeller, Viton Mechanical Seal, 6 Inch Flanged Inlet x 4 Inch Flanged Discharge, and is close coupled to a 20 Horsepower, 1750 RPM, 60 HZ, 230/460 Volt, 3 Phase, DPPE (Open Drip Proof, Premium Efficiency) 256JM frame Motor. The Goulds 3656 Series pumps are designed for a variety of water supply, recirculation, and cooling applications, with an enclosed silicon-brass impeller, dynamic balancing, and replaceable bronze wear rings to reduce losses and extend pump life. The close-coupled design mounts the pump directly to the motor, saving space and eliminating coupling alignment and re-alignment after service, and back pull-out construction allows the rotating element to be removed without disturbing the piping or moving the motor for shorter maintenance downtime. Replaceable wearing components, including a stainless steel shaft sleeve and casing and hub wear rings, allow the parts subject to wear to be renewed rather than replacing larger pump components. A rigid cast iron motor adapter provides support, with registered fits maintaining positive pump and motor alignment without shimming. Bearings are located in and are part of the motor. Units may be installed horizontally, inclined or vertically with the motor above the pump. The pump uses a Carbon/Silicon Carbide/Viton Type 21 mechanical seal and Viton O-rings/gaskets rated for liquid temperatures up to 250 degrees F (121 degrees C). Suction and discharge connections are 6 Inch Flanged Inlet x 4 Inch Flanged Discharge, 125 lb. ANSI flanged, and rotation is clockwise when viewed from the motor end.
