AMT 4201-95 Centrifugal Straight Pump replaces 420A-95 (Cast Iron, 5 HP, 3-Phase, 1750 RPM, 2" x 1-1/2" NPT Ports)

The AMT 4201-95 is a heavy-duty 5 HP, 1750 RPM straight centrifugal end-suction pump designed for continuous-duty industrial, commercial, OEM, circulation, liquid-transfer, heating/cooling, pressure-boosting, and sprinkler applications. The pump features a durable cast iron construction, precision-cast silicon bronze impeller, bronze case wear ring, and a Viton® silicon carbide/carbon mechanical seal.

The pull-from-rear design allows the pump to be serviced without disturbing the connected piping. The pump also includes 1/4" NPT gauge taps on the suction and discharge ports for system monitoring, front drain plugs, and a seal flush/air relief valve.

The 4201-95 uses a 1750 RPM TEFC 182JM motor, operating at 208-230/460 VAC, 3-phase, 60 Hz, with 22/11 full-load amps. The pump handles solids up to 1/4" diameter and requires a flooded suction with positive suction pressure.
