Pleuger deep well submersible pump units are single-stage or multi-stage centrifugal pumps, typically coupled with water-filled motors as standard. They can be fitted with oil-filled motors for special applications. The motor is assembled below the pump and the suction area is located above the motor. Deep well units are available as standard configuration from 4" motor size or as customized design from 6" motor size.
