Product Description

Zenit UNIQA ZUG-V Vortex Pump

The Zenit UNIQA ZUG-V Vortex Pump provides heavy-duty submersible pumping for soiled biological liquids and unscreened wastewater. Its cast-iron vortex impeller creates a full free passage; therefore, solids can move through the pump without travelling directly through narrow impeller channels.

Moreover, the UNIQA vortex submersible pump combines dependable solids handling with a Premium IE3 motor design. Consequently, it suits municipal, agricultural and industrial wastewater systems across India.

Zenit ZUG-V Full-Passage Vortex Pump Design

The Zenit UNIQA ZUG-V Vortex Pump uses a cast-iron vortex impeller positioned away from the main liquid flow. As a result, wastewater and compatible solids pass through the casing with reduced direct contact with the impeller.

In addition, the full free passage helps reduce fouling and blockage risks. Therefore, the Zenit vortex pump suits wastewater containing dirt, pollutants and suspended solids.

Key Features and Benefits

The Zenit ZUG-V range provides:

  • Cast-iron vortex impeller
  • Full free-passage hydraulics
  • Suitability for biological wastewater
  • Capability for unscreened wastewater
  • 3–45 kW power range at 50 Hz
  • Two- and four-pole motor options
  • DN65–DN150 discharge sizes
  • Free passage up to 150 mm at 50 Hz
  • Maximum 50 Hz flow up to 107.9 l/s
  • Maximum 50 Hz head up to 79.2 m
  • Premium IE3 motor design
  • WET and DRY installation versions
  • Dual silicon-carbide mechanical seals
  • Seal-chamber moisture monitoring
  • Hazardous-area versions available

Together, these features make the Zenit UNIQA ZUG-V Vortex Pump suitable for professional sewage and wastewater applications.

UNIQA Vortex Pump Performance

At 50 Hz, the ZUG-V wastewater pump range provides:

  • Motor power: 3–45 kW
  • Motor poles: Two or four
  • Discharge sizes: DN65–DN150
  • Maximum free passage: 150 mm
  • Maximum flow: 107.9 l/s
  • Maximum head: 79.2 m

Meanwhile, the 60 Hz range covers 7.5–37 kW and reaches flow rates up to 89.3 l/s, heads up to 81.6 metres and free passage up to 125 mm.

However, these figures represent separate maximum limits. Therefore, engineers should select the exact pump from its model-specific hydraulic performance curve.

ZUG-V Non-Clogging Wastewater Hydraulics

The vortex action keeps much of the wastewater and solids away from direct impeller contact. Consequently, the Zenit ZUG-V sewage pump can reduce blockage risks when liquids contain irregular suspended solids.

Moreover, the large free passage supports pumping stations with variable inflow and intermittent operating cycles. As a result, the pump can suit sewage collection tanks and wastewater systems that remain inactive for periods before restarting.

IE3 Motor Efficiency

Zenit designs UNIQA motors to target Premium IE3 efficiency according to EN 60034-30. Therefore, the Zenit UNIQA ZUG-V Vortex Pump combines solids-handling performance with controlled energy consumption.

In addition, Zenit matches the motor and hydraulic combination to the intended duty point. Consequently, the modular design helps avoid unnecessary motor oversizing.

Mechanical Seals and Monitoring

The UNIQA wastewater pump uses two silicon-carbide mechanical seals inside an oil chamber. Moreover, an oil-lifter component helps maintain lubrication around the upper seal.

A moisture probe also monitors the seal chamber. Therefore, operators can identify possible water ingress early and schedule maintenance before a seal problem causes an unexpected shutdown.

WET and DRY Installation Versions

The WET ZUG-V pump operates fully submerged inside a sump or wet well. Alternatively, the DRY version can operate while partially submerged or installed inside a dry chamber.

The DRY UNIQA vortex pump uses an internal closed cooling circuit. Consequently, suitable installations require no external cooling-water supply during normal operation.

Zenit ZUG-V Material Options

Standard UNIQA vortex hydraulics use EN-GJL 250 cast iron. Alternatively, selected configurations may use:

  • AISI 316 stainless steel
  • AISI 329 Duplex
  • Molib-tech materials

Therefore, engineers can configure suitable ZUG-V pumps for more demanding wastewater conditions. However, material availability depends on the selected model and configuration.

Zenit ZUG-V Applications in India

The Zenit UNIQA ZUG-V Vortex Pump may support applications across India such as:

  • Municipal sewage pumping stations
  • Unscreened wastewater lifting
  • Biological wastewater transfer
  • Livestock-farm wastewater
  • Industrial wastewater treatment
  • First-rain collection tanks
  • Wastewater containing suspended solids
  • Commercial sewage systems
  • Contaminated drainage water
  • Process wastewater transfer

Moreover, the full free passage supports wastewater containing dirt, solids and pollutants. However, heavily fibrous material may require a dedicated grinder or chopper pump instead.

Hazardous-Area Configurations

Zenit offers selected ATEX and IECEx-certified UNIQA configurations for potentially explosive environments.

However, certification depends on the exact pump version. Therefore, engineers should verify the nameplate, hazardous-area classification and supporting documentation before installation.

Selecting the Correct Zenit ZUG-V Pump

Correct selection depends on:

  • Required flow and total head
  • Solids size
  • Wastewater characteristics
  • Sump dimensions
  • Installation method
  • Motor power
  • Operating frequency
  • Discharge size
  • Material requirements
  • Hazardous-area classification

Therefore, engineers should select the Zenit UNIQA ZUG-V Vortex Pump from model-specific performance data. Otherwise, an unsuitable configuration may reduce efficiency, increase maintenance requirements or shorten pump life.
