*Values should be as indicated between any 2 power leads.
Note: Resistance values include 30’cable, and should be within +/- 10% of above value.
Above 30 HP, resistance values between 230 and 460 volt machines vary by less than 0.1 ohm. Consult
factory with specific requirements.
Impeller Bolt Torque: 10MM- 26FT#, 12MM-45FT#, 16MM-108FT#, 20MM- 210FT#
Impeller to Bottom Plate Clearance: (ASC) .020” minimum clearance.
Pump Rotation Right hand (CW) looking down from top of motor, CCW looking at bottom of pump.
Seal Probes: N motor pumps use a 12mm seal probe P motor pumps use 20mm seal probe.
Single wire probes are for non classified areas, and 2 wire probes are for Hazardous areas.
