Product Description
Zenit UNIQA ZUG-CP Chopper Pump
The Zenit UNIQA ZUG-CP Chopper Pump is a heavy-duty electric submersible pump for wastewater containing solids, fibres and destructible debris. Its chopper hydraulic system cuts troublesome material before discharge. Therefore, the pump helps reduce clogging in demanding sewage and industrial wastewater systems.
Moreover, the UNIQA chopper submersible pump combines strong solids-handling capability with efficient hydraulic performance. Selected 50 Hz models provide flow rates up to 281.6 l/s and heads up to 82.7 metres.
Zenit UNIQA ZUG-CP Chopper Pump Design
The Zenit UNIQA ZUG-CP Chopper Pump uses an open-channel impeller manufactured from hard cast iron as standard. In addition, a robust cutting component works close to the impeller blades to reduce destructible solids and fibrous material.
Consequently, the Zenit solids-cutting pump can handle heavily contaminated wastewater while maintaining a large hydraulic passage. Moreover, its hydraulic efficiency remains close to that of a conventional channel impeller.

Together, these features make the Zenit UNIQA ZUG-CP Chopper Pump suitable for municipal, commercial and industrial wastewater applications.
ZUG-CP Wastewater Pump Performance
The 50 Hz range provides:
- Motor power: 1.5–75 kW
- Motor poles: Two, four or six
- Discharge sizes: DN80–DN200
- Free passage: Up to 80 mm
- Maximum flow: 281.6 l/s
- Maximum head: 82.7 m
Meanwhile, selected 60 Hz models provide flow rates up to 129.5 l/s and heads up to 76.1 metres.
However, these figures represent separate maximum limits across the overall range. Therefore, engineers should select each UNIQA chopper pump from its model-specific hydraulic performance curve.
Hard-Cast-Iron Chopper Hydraulics
The ZUG-CP sewage pump uses a hard-cast-iron impeller to withstand demanding wastewater conditions. Consequently, the hydraulic system supports applications containing fibres, solids and other destructible debris.
Moreover, selected UNIQA configurations may use alternative hydraulic materials such as stainless steel, Duplex or Molib-tech. However, material availability depends on the specific pump model and operating duty.
IE3 Motor and Motor Protection
Zenit designs the UNIQA motor to achieve Premium IE3 efficiency according to EN 60034-30. Therefore, the Zenit UNIQA ZUG-CP Chopper Pump combines high hydraulic output with efficient motor performance.
In addition, Class H insulation and integrated thermal protection support demanding operating cycles. Consequently, these features help protect the motor during continuous wastewater duties.
WET and DRY Installation Versions
The WET version operates as a conventional submerged wastewater pump. Alternatively, the DRY version can operate while partially submerged or installed inside a dry chamber.
The DRY motor uses a closed water-glycol cooling circuit, an axial recirculation impeller and a stainless-steel double jacket. Therefore, suitable dry-installed configurations can operate without an external cooling-water supply.
Mechanical Seals and Monitoring
The Zenit UNIQA ZUG-CP Chopper Pump uses two silicon-carbide mechanical seals inside a large oil chamber. Moreover, an oil lifter maintains lubrication around the upper seal during operation.
A moisture sensor monitors the seal chamber. Consequently, operators can identify possible seal leakage early and plan maintenance before a major shutdown occurs.
Zenit ZUG-CP Applications in India
The UNIQA chopper submersible pump may support wastewater applications across India such as:
- Unscreened sewage
- Black-water lifting
- Wastewater containing fibres
- Municipal sewage pumping stations
- Industrial wastewater treatment
- Livestock wastewater
- Commercial building sewage
- First-rain collection tanks
- Heavily contaminated drainage water
- Mixed destructible solids
Moreover, the high-flow solids-cutting design can support rapid sump emptying. As a result, suitable installations may help reduce sediment accumulation inside wastewater collection chambers.
Hazardous-Area Configurations
Zenit offers ATEX and IECEx configurations for selected hazardous-area applications.
In addition, WET versions may support gas-area installations, while selected DRY configurations may suit gas and combustible-dust environments. However, engineers should confirm the exact certification marking for the chosen ZUG-CP model before installation.
Selecting the Correct Zenit ZUG-CP Pump
Correct selection depends on:
- Required flow and total head
- Solids size and type
- Fibre content
- Wastewater density
- Sump dimensions
- Installation method
- Power supply and frequency
- Discharge size
- Motor rating
- Cooling arrangement
- Hazardous-area requirements
Therefore, engineers should select the Zenit UNIQA ZUG-CP Chopper Pump from model-specific hydraulic data. Otherwise, an incorrect configuration may reduce flow, increase clogging risk or shorten equipment life.
