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, fish farming and industrial water systems. Moreover, Zenit redesigned the Grey Series hydraulics and motors to support high performance, lower energy use and reliable 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 produces the pressure required for long pipe runs, elevated outlets and pressurised water distribution.
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 of the Grey APG Submersible Pump
- 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 of 51.9 m
- Maximum 60 Hz head of 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 clean-water and high-pressure transfer systems.
APG Alta Prevalenza Pump Performance
At 50 Hz, the APG Alta Prevalenza pump range covers 1.1–7.5 kW. Moreover, selected models deliver up to 10.5 l/s and reach a maximum head of 51.9 metres.
Meanwhile, the 60 Hz range covers the same published power band. It also reaches 10.5 l/s; however, selected configurations develop up to 59 metres of head.
These figures represent separate range-wide limits. Therefore, engineers must select each APG industrial water pump from its model-specific performance curve.
Zenit High-Pressure Water Pump Hydraulics
The multi-channel open impeller moves clean water efficiently while producing significant discharge pressure. As a result, the Zenit high-pressure water pump supports sprinkler systems, elevated tanks, fountains and industrial washing equipment.
Moreover, the conical impeller coupling creates a secure mechanical connection. Therefore, the design supports reliable power transmission during demanding operating cycles.
Grey APG Pump Motor and Protection
The Grey APG pump uses a two-pole submersible motor with Class H insulation and IP68 protection. In addition, thermal devices inside the stator protect the motor against excessive temperature.
Consequently, the motor supports demanding professional applications. However, operators must still provide suitable electrical controls, overload protection and level management.
APG Submersible Pump Seals and Shaft
The APG submersible pump uses an AISI 431 stainless-steel drive shaft. Moreover, two silicon-carbide mechanical seals protect the motor from the pumped liquid.
Zenit places both seals inside a large, inspectable oil chamber. As a result, the oil lubricates and cools the seal faces while protecting them from contaminants.
In addition, a moisture probe monitors the mechanical-seal chamber. Therefore, operators can detect water ingress and schedule maintenance before serious damage develops.
Zenit APG Installation Options
Zenit supports free-standing and permanent installation of the Grey APG submersible pump. Alternatively, engineers can install the unit with a compatible vertical or horizontal bottom-coupling system.
Consequently, users can remove the pump for maintenance without entering the collection chamber. Moreover, bottom coupling helps maintain accurate alignment with the discharge pipe.
Grey APG Operating Conditions
The published Grey Series operating 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 limits describe the wider Grey Series. Therefore, engineers should confirm the final limits for the exact Zenit Grey APG High Head Pump model and application.
APG High-Head Pump Applications
The Zenit APG high-head pump suits:
- Industrial washing systems
- Commercial car washes
- Agricultural irrigation
- Sprinkler systems
- Fountains and water features
- Fish-farming installations
- Aquaculture circulation
- Clean-water lifting
- Reservoir transfer
- Rainwater reuse
- Process-water distribution
- High-pressure drainage
Moreover, the APG pump suits applications that need pressure rather than large solids passage. Nevertheless, sewage or heavily contaminated wastewater requires another Grey hydraulic type.
ATEX Grey APG Pump Options
Zenit offers selected Grey Series models with ATEX certification for potentially explosive atmospheres. The published marking is II 2G Ex db h IIB T4 Gb.
However, certification depends on the exact pump configuration. Therefore, buyers must verify the ordered APG pump’s nameplate, certificate and permitted installation conditions.
Selecting a Zenit APG High-Head Pump
Correct selection depends on required flow, total head, pipe length, elevation and water quality.
In addition, engineers should confirm the voltage, frequency, motor rating, discharge connection and installation method. Therefore, specialists 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.
