Product Description
Zenit Grey APG High Head Pump
The Zenit Grey APG High Head Pump provides high-pressure submersible pumping for clean water and compatible liquids containing only small particles. Its cast-iron multi-channel open impeller develops high manometric head while maintaining efficient water transfer.
Therefore, the APG pump suits irrigation, car washes, fountains, aquaculture and industrial water systems across India. Moreover, Zenit designed the Grey Series hydraulics and motors to support strong performance, controlled energy use and dependable operation.
Zenit APG High-Head Pump Design
The Zenit Grey APG High Head Pump uses a cast-iron multi-channel open impeller. Consequently, the hydraulic design develops the pressure required for long pipe runs, elevated outlets and pressurised water-distribution systems.
In addition, the APG high-head submersible pump provides free passage up to 10 mm. Therefore, it suits clean or lightly contaminated water rather than sewage containing large solids, fibres or filaments.
Key Features and Benefits
The Grey APG submersible pump provides:
- Cast-iron multi-channel open impeller
- High manometric head
- Power range from 1.1 to 7.5 kW
- Two-pole motor construction
- 50 Hz and 60 Hz configurations
- Maximum flow up to 10.5 l/s
- Maximum 50 Hz head up to 51.9 m
- Maximum 60 Hz head up to 59 m
- Free passage up to 10 mm
- Horizontal discharge connections
- Class H motor insulation
- IP68 protection
- AISI 431 stainless-steel shaft
- Two silicon-carbide mechanical seals
- Oil-chamber leakage sensor
- Optional ATEX configuration
Together, these features make the Zenit Grey APG High Head Pump suitable for professional high-pressure clean-water applications.
APG High-Head Pump Performance
At 50 Hz, the APG range covers motor ratings from 1.1 to 7.5 kW. Moreover, selected models deliver flow rates up to 10.5 l/s and heads up to 51.9 metres.
Meanwhile, selected 60 Hz configurations also reach 10.5 l/s while developing heads up to 59 metres.
However, these values represent separate maximum limits across the range. Therefore, engineers should select each APG pump from its model-specific hydraulic performance curve.
High-Pressure Water Pump Hydraulics
The multi-channel open impeller transfers clean water efficiently while developing significant discharge pressure. As a result, the Zenit APG pump can support sprinkler systems, elevated tanks, fountains and industrial washing equipment.
Moreover, the conical impeller coupling provides a secure mechanical connection. Consequently, the hydraulic assembly supports reliable power transmission during demanding operating cycles.
Grey APG Motor and Protection
The Zenit Grey APG High Head Pump uses a two-pole submersible motor with Class H insulation and IP68 protection.
In addition, thermal devices inside the stator protect the motor from excessive temperature. Therefore, the unit can support demanding professional applications when used with suitable electrical controls, overload protection and level management.
Mechanical Seals and Shaft
The APG pump uses an AISI 431 stainless-steel drive shaft. Moreover, two silicon-carbide mechanical seals separate the motor from the pumped liquid.
Zenit positions both seals inside a large oil chamber. Consequently, the oil lubricates and cools the seal faces while reducing exposure to contaminants.
In addition, a moisture probe monitors the seal chamber. Therefore, operators can detect water ingress and plan maintenance before significant damage develops.
Zenit APG Installation Options
Zenit supports free-standing and permanent installations for the Grey APG pump. Alternatively, engineers can use compatible vertical or horizontal bottom-coupling systems.
Consequently, operators can remove the pump for servicing without entering the collection chamber. Moreover, bottom coupling helps maintain alignment with the discharge pipe.
Grey APG Operating Conditions
Published Grey Series limits include:
- Maximum liquid temperature: 40°C
- Permitted liquid pH: 6–14
- Maximum immersion depth: 20 m
- Maximum liquid density: 1.1 kg/dm³
- Maximum acoustic pressure: Below 70 dB
- Maximum starts per hour: 20 below 10 kW
However, these values describe the wider Grey Series. Therefore, engineers should confirm the final operating limits for the selected APG model.
Zenit APG Applications in India
The Zenit Grey APG High Head Pump may support applications across India such as:
- Agricultural irrigation
- Sprinkler systems
- Commercial car washes
- Industrial washing systems
- Fountains and water features
- Fish farming and aquaculture
- Clean-water lifting
- Reservoir transfer
- Rainwater reuse
- Process-water distribution
- High-pressure drainage
- Water-transfer systems
Moreover, the APG pump suits applications that require pressure rather than large solids passage. However, sewage or heavily contaminated wastewater requires a more suitable solids-handling hydraulic design.
ATEX Grey APG Options
Zenit offers selected Grey Series models with ATEX certification for potentially explosive atmospheres.
However, certification depends on the exact configuration. Therefore, engineers should verify the pump nameplate, certification and permitted installation conditions before use in hazardous areas.
Selecting the Correct Zenit APG Pump
Correct selection depends on:
- Required flow and total head
- Pipe length and diameter
- Elevation
- Water quality
- Voltage and frequency
- Motor rating
- Discharge connection
- Installation method
Therefore, engineers should select the Zenit Grey APG High Head Pump from its individual hydraulic curve. Otherwise, an incorrectly sized pump may consume excessive energy or fail to provide the required pressure.
