UNIQA Series electric submersible pumps

UNIQA series pumps, designed for heavy-duty professional applications, are used in industrial and other wastewater treatment plants and for lifting sewage and pumping wastewater which contains solids.

Motors are designed with the aim of achieving the Premium (IE3) efficiency class according to the EN 60034-30 standard and guarantee high performance with low energy use. There are various types of hydraulics, to adapt perfectly to any type of application.

Models are available with:
  • vortex impeller (ZUG V)with full free passage;
  • channel impeller (ZUG OC) with anti-clogging and anti-fouling system;
  • high head (ZUG HP) capable of high hydraulic performances;
  • grinding system (ZUG GR) for use with soiled liquids and filaments.

Depending on the service required, each model comprises a motor-hydraulics combination chosen to provide optimal performance at the duty point, low energy use, and high reliability, thanks to the use of the materials best suited to the type of application.
The entire range is available in the DRY version, which requires no external liquid inputs and allows the electric pump to operate continually (S1 duty) even if partially submerged or installed in a dry chamber.

Details

Zenit Uniqa Series electric submersible pump cable gland

On request the cable entry point can be sealed with resin, preventing all possibility of water seeping inside the motor cover even if the cable's outer sheath is torn.

Zenit Uniqa Series electric submersible pump drive shaft

Drive shaft in AISI 431 stainless steel. DUPLEX steel shaft available as optional.

Zenit Uniqa Series electric submersible pump bearings

Oversized bearings to guarantee 50000 working hours.

Zenit Uniqa Series electric submersible pump mechanical seals

Two silicon carbide mechanical seals in the oil chamber and V-rings. The oil can be be checked and changed even with the pump vertical, using plugs on the outside of the mount.

Zenit Uniqa Series electric submersible pump motor compartment

Possibility to equip the pump with many different optional probes to detect any anomaly. Humidity probe to detect water in the mechanical-seal oil-chamber standard also for ATEX version.

Zenit Uniqa Series electric submersible pump flanges

Various flange drilling are available, including ANSI and BS.

Zenit Uniqa Series electric submersible pump high efficiency motor

Motor designed with the aim of achieving the PREMIUM (IE3) efficiency class according to EN 6034-30. Operation guaranteed in S1 mode even in water at a temperature of 60°C or above. Generally, since energy costs are higher than other expenses, continuous duty provides higher savings compared to a conventional system and the initial investment in a high efficiency systems is soon recouped, without considering the considerable advantages in terms of environmental footprint.

Zenit Uniqa Series electric submersible pump clogging proof hydraulics

All hydraulic components are designed for the highest efficiency and the best performance while still ensuring ample free passages.
Impellers are available in cast-iron, stainless steel , bronze/aluminium or Molib-tech™, an innovative treatment that assures a much longer life compared to traditional ceramic paint.
All models with channel hydraulics feature an axial adjustment system allowing the impeller clearance to be restored, to maintain performance even further to normal wear and tear.
The ACS (Anti-Clogging System) consists of a spiral groove of suitable depth cut into the diffuser plate.
This prevents clogging of the impeller even with highly fouled liquids, allows stringy items to be pulled out or unwound and renders the hydraulics clogging-proof.

Zenit Uniqa Series electric submersible pump modularity

The UNIQA series features a modular design in which the motor and hydraulics are perfectly coupled to each other. This characteristic allows the creation of particularly reliable units, thanks to the use of materials specific for the intended type of liquid and achievement of top performances, since every component is optimised for the duty point and of suitable size to guarantee minimal energy use.

Zenit Uniqa Series electric submersible pump cooling system

The motor is cooled by means of a patented internal "closed circuit" system. This ensures that there is no adulteration of the fluid used even if contaminated liquid accidentally enters the oil chamber due to wear of the first mechanical seal.
Continuous duty is ensured even in dry and partially submerged working conditions.

Zenit Uniqa Series electric submersible pump atex

On request available ATEX version of the pump suitable for installation in potentially explosive atmosphere. Humidity probe to detect water in the mechanical-seal oil-chamber is standard also for ATEX version.
