Electric motors from series HT are 2 pole asynchronous three-phase submersible motors designed to operate coupled to hydraulic parts with 4” Nema standard. They are made of materials suitable for contact with water, and cooling and lubrication of the thrust block and bushes are guaranteed by a mixture of water and glycol.
HT motors require a start, operation and protection system. Supply cable connector, removable for quick and easy maintenance.
APPLICATIONS
HT encapsulated water-cooled motors ensure reliable working in 4” or larger diameter wells and are designed to be used for lifting, distribution, and pressurisation of water in water systems. HT motors are equipped with phase separator which ensures optimal operation when the motor is used with frequency inverter.
CHARACTERISTICS OF CONSTRUCTION
- 2 pole asynchronous three-phase encapsulated water-cooled motor.
- Axial and radial water-lubricated bearings allow for maintenance-free operation.
- Hermetically sealed stator by 304L stainless steel flanges, internal and external casings, filled by resin to guarantee optimal cooling capacity of temperature during operation.
- Rotor set on Kingsbury thrust block equipped with carbon clearance ring and oscillating pads in high-strength stainless steel to sustain high axial loads.
- Pre-filled with non-contaminating antifreeze lubricant liquid.
- Sand protection to guarantee optimal operation even with sand in the borehole.
- Removable lead connector to make installation and maintenance easier.
- Supply cable according to drinking water regulations (ACS), available in different lenghts.
