VERTICAL HOLLOW SHAFT MOTORS

VERTICAL HOLLOW SHAFT MOTORS The following table shows the bases that fit each of the Hp/frame sizes. Proper alignment of pump flange and motor flange is critical. Small errors in alignment are magnified by the distance from the flange to the top of the motor, resulting in vibration, electrical noise, premature bearing wear and oil leakage.
