Control panels

Zenit electronic and electromechanical control panels are suitable for the control of any single-phase or three-phase submersible pump, with direct or star/delta starting.

Rational wiring

All internal wiring layouts are designed to be clear and rational. The connection cables are identified with numbered labels for easy reference to the wiring diagram and to facilitate any work by technical personnel. In addition, meticulous assembly translates into a better-quality product with less risk of faults and malfunctions.


Control panels are made using the best components available, to guarantee excellent reliability and easy procurement of replacement parts. They undergo strict functional and quality checks before delivery.


Zenit electromechanical and electronic control panels are optimized for use with submersible pumps and the wide range of accessories make them versatile and reliable. Having just one contact for the supplying of control systems and machines translates into definite advantages in economic terms and with regard to intervention times.

Standard compliance

Every control panel is created in compliance with the current standards on electrical constructions. All control panels come with complete documentation, electric diagrams and CE declaration of conformity.


Zenit domestic and civil electromechanical and electronic control panels

Electronic standard

ZENIT electronic control panels designed to control 1, 2 or 3 single-phase pumps with power from 0.37 kW up to 2.2 kW or 1, 2 or 3 three-phase pumps with power from 0.55 kW up to 15 kW.
The exceptional operational versatility reduces the amount of stock required, since a single panel covers various powers. Designed for use with float switches or level sensors, they allow users to set alternating pump duty cycles and maximum or minimum level alarm output.
