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 contact against the impeller.
Moreover, Zenit developed the bluePRO Series for prolonged operation in domestic, residential and small civil installations. Consequently, the pump combines convenient handling 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 reduces clogging risks when sewage contains compatible suspended solids.

Together, these features make the Zenit DG bluePRO Pump suitable for residential sewage lifting, domestic wastewater stations and small civil plants.
DG bluePRO Hydraulic Performance
The 50 Hz DG bluePRO wastewater pump range covers motor ratings from 0.37 to 1.5 kW. Moreover, selected models deliver up to 756 l/min, which equals approximately 12.6 l/s.
In addition, the range develops heads up to 15.3 metres. However, maximum flow and maximum head apply to different operating points across the complete product range.
Therefore, engineers should select the exact pump from its individual hydraulic curve instead of assigning both maximum values to every configuration.
Full Free-Passage Hydraulics
Selected models provide free passage up to 50 mm. Consequently, the bluePRO sewage 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 include a grinder or chopper system.
Therefore, wastewater containing wipes, long fibres or difficult filamentary material may require a dedicated grinder pump after a full application review.
Durable Motor and Construction
Zenit manufactures the pump casing and impeller from EN-GJL-250 cast iron. In addition, the pump uses an AISI 431 stainless-steel shaft, stainless-steel fasteners and durable sealing components.
Consequently, the DG bluePRO sewage pump provides robust construction for prolonged domestic and residential wastewater duties.
Furthermore, a protective epoxy coating helps resist external corrosion. The compact motor design also supports convenient handling during installation and maintenance.
Mechanical Seals and Pressure Testing
The Zenit DG bluePRO 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 protects the mechanical seals from foreign material. Zenit pressure-tests every unit to check the motor compartment, gaskets, cable gland and sealing system.
Consequently, these quality-control procedures support reliable assembly and operation.
DG bluePRO Installation Options
The DG bluePRO vortex pump supports free-standing and fixed installations. Alternatively, installers can use a compatible coupling system where the pumping station requires convenient pump removal.
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.
Zenit also designed the range for use with compatible blueBOX lifting stations.
Operating Limits
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 metres
- Maximum liquid density: 1 kg/dm³
- Maximum starts: 30 per hour
However, users must confirm the precise operating limits of the selected model before installation.
Applications for the Zenit bluePRO Sewage Pump
The Zenit bluePRO sewage pump suits:
- 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
However, clean drainage, seepage water and floodwater without significant solids may suit Zenit DR bluePRO hydraulics more closely.
IECEx-Certified Versions
Zenit offers selected IECEx-certified bluePRO configurations for specified potentially explosive environments.
However, certification does not apply automatically to every model. Therefore, buyers must verify the precise marking, approval and permitted installation conditions on the ordered pump’s nameplate and certificate.
Choosing the Correct DG bluePRO Model
Correct selection depends on required flow, total head, solids size, wastewater composition and sump arrangement.
In addition, engineers should confirm the electrical supply, phase, discharge size, installation method and certification requirements. Therefore, specialists should select the Zenit DG bluePRO Pump from model-specific hydraulic data.
Otherwise, an unsuitable pump may operate inefficiently, clog frequently or fail to deliver the required flow.
