Exclusive cooling system for Uniqa

zenit uniqa electric pump patented cooling system
The UNIQA range is designed to meet the needs of civil and industrial wastewater pumping applications.
Efficiency is a top priority: an energy-saving class IE3 motor combined with high-efficiency hydraulics, optimised for the duty point.
Reliability to guarantee trouble-free operation with low maintenance, and innovation to deliver a better product, are 2 additional key concepts we view as fundamental to stand out from the competition. 
This is reflected by the exclusive cooling system, designed by our engineers. In DRY version models, the motor is cooled by a water-glycol mix circulating in a special closed circuit.
The mix is recycled through the pump by an axial impeller rigidly mounted on the shaft and the specially designed steel double jacket which provides the necessary heat exchange between the motor and the external environment.

Thanks to this unique system:
  • the cooling mix is always separate from the wastewater in which the pump is immersed and cannot be contaminated even if water leaks into the oil chamber due to wear of the first mechanical seal;
  • the mechanical seals are installed in an oil chamber separated from the cooling system and can be changed without draining the circuit.

Continuous operation of the pump (S1 duty) is ensured even in dry and partially submerged working conditions or in high temperature locations.
This specific characteristic, combined with the high-efficiency motors and hydraulics and modular designs, ensures the ideal solution to the needs of civil and industrial wastewater pumping applications. Download the Uniqa Catalogue
