X.H3H

X.H3H single-phase pump for open circuit systems for heat pumps (220-230V/50 Hz)

4” complete submersible pump, made of stainless steel ZDS hydraulic part, Franklin single-phase encapsulated PSC water-cooled motor, supply cable in different lenghts and ZDS CBH electrical start panel (which includes start and run capacitor), especially developed for installation in open circuit systems for heat pumps.

This motor achieves between 5 to 7% points higher efficiency than standard sumbersible motors of the same power rating. This special and unique combination of products offers low power consuption and high efficiency, and represents the best system for heating applications.

Automatic protections

Current overload protection

The ZDS Control Box protects the pump against overload. In case the pump is partially or totally blocked, the overload protection in the ZDS Control Box stops the pump to protect it.

Information on a proper installation

If you are using a generator with an internal combustion engine, it is necessary that the generator’s power measured in kW (in continuous delivery) is three times the rated power in kW of the submersible pump.
We recommend to install a proper cooling jacket in installations bigger than 10 cm, to guarantee the correct motor cooling flow.
In order to reset the overload protection sensor, it is necessary to press the appropriate button on the CBH.
