Product Description
Zenit DG blue Pump
The Zenit DG blue Pump provides compact submersible pumping for sewage and soiled wastewater containing compatible solids. Its techno-polymer 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 blue Series mainly for domestic and residential installations. Consequently, the pump combines reliable wastewater handling with convenient transport, installation and routine maintenance.
Vortex Hydraulics for Domestic Sewage
The Zenit DG blue Pump uses a techno-polymer vortex impeller inside an EN-GJL-250 cast-iron casing. During operation, the impeller creates a swirling flow inside the hydraulic chamber.
As a result, much of the wastewater moves around the impeller instead of passing through narrow hydraulic channels. Therefore, the DG blue vortex pump helps reduce fouling when sewage contains compatible suspended solids.
Key Features and Benefits
The Zenit DG blue range provides:
- Techno-polymer vortex impeller
- EN-GJL-250 cast-iron casing
- Full free passage of 40 mm
- Motor range from 0.30 to 0.74 kW
- Two-pole single-phase motor
- 50 Hz and 60 Hz versions
- Vertical G1½-inch discharge
- Maximum flow up to 7.8 l/s
- Maximum head up to 12 m
- Class F motor insulation
- IP68 protection
- Integrated thermal protection
- Adjustable float-switch option
- Maximum immersion depth up to 20 m
Together, these features make the Zenit DG blue Pump suitable for domestic wastewater systems and small residential lifting stations.
DG blue Hydraulic Performance
The 50 Hz DG blue wastewater pump range covers models from 0.30 to 0.74 kW. Moreover, the complete range reaches flow rates up to approximately 7.8 l/s and heads up to 12 metres.
However, maximum flow and maximum head occur at different operating points. Therefore, users should select the exact pump from its model-specific hydraulic curve rather than applying both maximum values to every configuration.
Full Free-Passage Design
Published DG blue models provide a 40 mm full free passage. Consequently, the pump can transfer compatible wastewater solids that may obstruct smaller hydraulic passages.
Moreover, vortex hydraulics reduce direct contact between solids and the impeller. Nevertheless, the pump does not grind or cut material.
Therefore, users should prevent wipes, long fibres, metal objects and other unsuitable debris from entering the sump. Applications containing difficult fibrous waste may require a dedicated grinder or chopper pump instead.
Motor and Electrical Protection
The Zenit DG blue Pump uses a two-pole single-phase motor with Class F insulation and IP68 protection.
In addition, thermal devices inside the stator help protect the motor from excessive temperature. Single-phase models also include an internal capacitor. Consequently, the pump provides a compact electrical arrangement for domestic and residential wastewater installations.
Mechanical Seals and Protection
The DG blue pump uses one silicon-carbide mechanical seal and one alumina-graphite mechanical seal inside an oil chamber. Therefore, the oil lubricates the sealing faces and supports dependable operation.
In addition, a V-ring helps protect the seals from foreign material. These features contribute to reliable performance during regular household and residential sewage duties.
DG blue Installation Options
The Zenit DG blue vortex pump supports free-standing and fixed installations. Alternatively, installers can use a compatible external coupling arrangement where easier pump removal is required.
Moreover, selected versions include an adjustable float switch. Therefore, users can set automatic start and stop levels according to the available sump volume.
This flexibility makes the Zenit DG blue Pump practical for compact wastewater pits, collection tanks and below-sewer-level installations.
Operating Conditions
Published operating conditions include:
- Maximum liquid temperature: 40°C
- Maximum immersion depth: 20 m
- Motor protection: IP68
- Motor insulation: Class F
- Vertical discharge: G1½ inch
- Single-phase electrical supply on applicable models
However, users should confirm the exact voltage, frequency, cable arrangement and model-specific operating limits before installation.
Zenit DG blue Applications in India
The Zenit DG blue Pump may support applications across India such as:
- Domestic sewage lifting
- Residential wastewater collection
- Apartment wastewater systems
- Small civil lifting stations
- Basement bathroom pumping
- Below-sewer-level installations
- Small commercial wastewater systems
- Collection tanks and sumps
- Temporary sewage transfer
- Compatible emergency wastewater pumping
Moreover, its compact size makes it practical for residential applications where installation space is limited.
However, clear floodwater, seepage water, irrigation or clean-water duties may require a dedicated drainage pump. Similarly, prolonged heavy-duty sewage applications may require a larger professional Zenit range.
Selecting the Correct Zenit DG blue Pump
Correct selection depends on:
- Required flow and total head
- Solids size
- Wastewater composition
- Pipe diameter
- Sump dimensions
- Electrical supply
- Float-switch requirement
- Installation method
- Discharge connection
Therefore, users should select the Zenit DG blue Pump from model-specific hydraulic data. Otherwise, an unsuitable model may cycle too frequently, operate inefficiently or fail to provide the required discharge head.
