Ordering
A motor code has eight positions — series and motor name, ring size (nominal torque rating), mounting flange and port connections, shaft, cover position, design number and special features. Send us the complete code from the nameplate and we will confirm the replacement motor; without the full code the torque rating and the port position cannot be identified.
Notes. Intermittent duty means 10%% of total operating time, never more than 6 seconds at a time. Minimum speed is normally 100 r/min. Motor codes are a separate system from vane pump codes and are not interchangeable.
