Product Description
Zenit DG bluePRO Pump
The Zenit DG bluePRO Pump provides heavy-duty submersible pumping for sewage and heavily soiled wastewater containing compatible solids. Its cast-iron vortex impeller creates a full free passage. Therefore, solids can move through the hydraulic casing with limited direct contact with the impeller.
Moreover, Zenit developed the bluePRO Series for prolonged operation in domestic, residential and small civil installations. Consequently, the pump combines compact construction with dependable wastewater performance.
Vortex Design of the DG bluePRO Pump
The Zenit DG bluePRO Pump uses an EN-GJL-250 cast-iron vortex impeller and cast-iron pump casing. During operation, the impeller creates a swirling flow inside the hydraulic chamber.
As a result, much of the wastewater moves around the impeller rather than through narrow channels. Therefore, the DG bluePRO vortex pump helps reduce clogging when sewage contains compatible suspended solids.
Key Features and Benefits
The DG bluePRO range provides:
- Cast-iron vortex impeller
- Full free-passage hydraulics
- Maximum free passage up to 50 mm
- Motor range from 0.37 to 1.5 kW
- Two-pole motor construction
- Single-phase and three-phase options
- G1½-inch and G2-inch vertical discharge
- Maximum flow up to 756 l/min
- Maximum head up to 15.3 m
- Two silicon-carbide mechanical seals
- Accessible oil chamber
- Mechanical-seal protection V-ring
- Maximum immersion depth up to 20 m
- IECEx-certified versions available
Together, these features make the Zenit DG bluePRO Pump suitable for residential sewage lifting, domestic wastewater stations and small civil applications.
DG bluePRO Hydraulic Performance
The 50 Hz DG bluePRO range covers motor ratings from 0.37 to 1.5 kW. Moreover, selected models deliver flow rates up to 756 l/min, or approximately 12.6 l/s.
In addition, the range develops heads up to 15.3 metres.
However, these figures represent separate maximum limits across the product range. Therefore, engineers should select the exact pump from its individual hydraulic curve rather than applying both maximum values to every model.
Full Free-Passage Hydraulics
Selected DG bluePRO models provide free passage up to 50 mm. Consequently, the pump can transfer wastewater containing compatible solids that may obstruct smaller hydraulic passages.
Moreover, vortex hydraulics reduce direct contact between suspended material and the impeller. Nevertheless, the pump does not use a grinder or chopper system.
Therefore, wastewater containing wipes, long fibres or difficult filamentary material may require a dedicated grinder or chopper pump.
Durable Motor and Construction
Zenit manufactures the pump casing and impeller from EN-GJL-250 cast iron. In addition, the Zenit DG bluePRO Pump uses an AISI 431 stainless-steel shaft, stainless-steel fasteners and durable sealing components.
Consequently, the pump provides robust construction for prolonged domestic and residential wastewater duties.
Furthermore, a protective epoxy coating helps resist external corrosion, while the compact motor design supports convenient installation and maintenance.
Mechanical Seals and Protection
The DG bluePRO sewage pump uses two silicon-carbide mechanical seals inside an oil chamber. Therefore, the oil lubricates and cools the sealing surfaces while separating them from wastewater contamination.
In addition, a V-ring helps protect the mechanical seals from foreign material. These features support dependable sealing during demanding wastewater operation.
Installation Options
The Zenit DG bluePRO Pump supports free-standing and fixed installations. Alternatively, installers can use a compatible coupling system where convenient pump removal is important.
Moreover, vertical-discharge models include an air-release arrangement. Therefore, the pump can release trapped air and restore normal operation after the collection tank empties.
The range also integrates with compatible blueBOX wastewater lifting stations.
Operating Conditions
Published bluePRO operating conditions include:
- Maximum continuous liquid temperature: 40°C
- Temporary liquid temperature: Up to 90°C for three minutes
- Permitted liquid pH: 6–14
- Maximum immersion depth: 20 m
- Maximum liquid density: 1 kg/dm³
- Maximum starts: 30 per hour
However, users should confirm the precise operating limits for the selected model before installation.
Zenit DG bluePRO Applications in India
The Zenit DG bluePRO Pump may support wastewater applications across India such as:
- Residential sewage lifting
- Domestic wastewater stations
- Apartment-building sewage systems
- Small civil lifting plants
- Commercial wastewater collection
- Basement sewage installations
- blueBOX lifting stations
- Wastewater containing compatible solids
- Small wastewater-transfer systems
- Emergency replacement duties
Moreover, its compact vortex design suits installations where dependable solids handling and straightforward maintenance are important.
However, clean drainage or seepage water without significant solids may require a more suitable drainage-pump hydraulic design.
IECEx-Certified Versions
Zenit offers selected IECEx-certified bluePRO configurations for specified potentially explosive environments.
However, certification does not apply to every model. Therefore, engineers should verify the exact nameplate marking, approval and permitted installation conditions before using the pump in a hazardous area.
Selecting the Correct DG bluePRO Model
Correct selection depends on:
- Required flow and total head
- Solids size
- Wastewater composition
- Sump dimensions
- Electrical supply
- Single-phase or three-phase requirement
- Discharge size
- Installation method
- Certification requirements
Therefore, engineers should select the Zenit DG bluePRO Pump from model-specific hydraulic data. Otherwise, an unsuitable model may operate inefficiently, clog frequently or fail to provide the required flow.
