Electric motors from series H2 are 2 pole asynchronous single-phase submersible motors designed to operate coupled to 4” ZDS hydraulic parts. 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. H2 motors are equipped with a special and unique start and run capacitor, which is designed to guarantee a long-life to the motor and avoid the installation of an external control panel. They also come with a special and manually resettable built-in thermal protection, which stops the motor when overheated.
Supply cable connector is removable for quick and easy maintenance.
APPLICATIONS
H2 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.
H2 motors can be installed with a frequency inverter.
CHARACTERISTICS OF CONSTRUCTION
