Pumptron submersible motor pumps are vertically mounted multi stage pumps. The pump is designed as external casing pump or as structured pump with radial or semi-axial impellers with a non-return valve as standard.

Our submersible motor is a three-phase synchronous motor with a short circuit rotor. It is designed for wet-running rewindable motor with a watertight insulated windings. The motor connections are 4, 6 and 8 inch are according to NEMA-standard, 3-, 10- and 12-inch are according to international standards. Motors are earthed inside and encapsulated by a mechanical seal. 3- and 4 inches pumps are available with single phase motors

Pumptron Submersible motor pumps shall be used in vertical configuration. However, and depending on the number of stages and motor power output, it may be used for horizontal or angular configurations. The bearings are lubricated by the pumped liquid or the motor coolant. Axial thrust is achieved by the axial thrust of bearing with special tilting pads.

Our standard international warranty is 1 year
