*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 very by less than 0.1 ohm. Consult factory
with specific requirements.
Impeller Bolt Torque:
10mm – 26ft lb / 35Nm, 12mm – 45ft lb / 61Nm, 16mm – 108ft lb / 146Nm, 20mm – 210 ft lb / 285Nm
Impeller to Bottom Plate Clearance: (ASC) .020" / 0,3mm 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.
