Product Description
Zenit DG steel Pump
The Zenit DG steel Pump is a compact stainless-steel submersible pump for sewage and soiled wastewater containing compatible solids. Its AISI 304 vortex impeller creates a large free passage. Therefore, wastewater can move through the hydraulic casing with limited direct contact with the impeller.
Moreover, Zenit developed the steel Series for household installations and small civil plants. Consequently, the pump combines corrosion resistance, compact construction and reliable wastewater lifting.
Stainless-Steel Vortex Hydraulic Design
The Zenit DG steel Pump uses an AISI 304 stainless-steel vortex impeller and 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 steel vortex pump helps reduce clogging when the liquid contains compatible suspended solids.
Key Features and Benefits
The Zenit DG steel range provides:
- AISI 304 stainless-steel vortex impeller
- AISI 304 stainless-steel pump casing
- Free passage up to 40 mm
- Motor range from 0.37 to 0.75 kW
- Two-pole motor construction
- Single-phase and three-phase options
- G1¼-inch and G1½-inch vertical discharge
- Maximum flow up to 6.7 l/s
- Maximum head up to 10.1 m
- AISI 431 stainless-steel shaft
- Silicon-carbide/alumina mechanical seal
- Adjustable float-switch options
- Thermal-overload protection
- Maximum immersion depth up to 10 m
Together, these features make the Zenit DG steel Pump suitable for compact residential and small civil wastewater installations.
DG steel Pump Performance
The 50 Hz DG steel sewage pump range includes 0.37, 0.55 and 0.75 kW models. Moreover, selected configurations provide flow rates up to approximately 6.7 l/s and heads up to 10.1 metres.
However, maximum flow and maximum head occur at different operating points. Therefore, users should select the exact model from its hydraulic curve rather than applying both maximum limits to every pump.
Full Free-Passage Operation
The smallest DG steel model provides a 25 mm free passage, while selected larger models provide up to 40 mm.
Consequently, the stainless-steel vortex pump can transfer compatible wastewater solids that may obstruct smaller hydraulic passages. Moreover, vortex hydraulics limit direct contact between suspended material and the impeller.
Nevertheless, the pump does not grind or cut waste. Therefore, users should prevent wipes, long fibres, stones, metal objects and other unsuitable debris from entering the collection chamber.
Compact Stainless-Steel Construction
Zenit manufactures the casing, impeller and handle from AISI 304 stainless steel. In addition, the drive shaft uses AISI 431 stainless steel for mechanical strength.
Consequently, the Zenit DG steel Pump combines corrosion resistance with relatively lightweight construction for domestic and compact wastewater installations.
Moreover, the insulated handle supports convenient transport, installation and maintenance.
Motor Protection and Cooling
The DG steel wastewater pump uses a dry motor with thermal-overload protection. In addition, an integrated cooling jacket helps control motor temperature during partially submerged operation.
Single-phase models include an internal capacitor. Meanwhile, the three-phase version includes a relay for float-switch control.
Therefore, users can select the electrical arrangement according to the installation and available power supply.
Mechanical Seal and Maintenance
The DG steel submersible pump uses a silicon-carbide/alumina mechanical seal inside a large oil chamber. In addition, a V-ring helps protect the sealing area from foreign material.
Consequently, the oil chamber provides lubrication and supports seal life. Moreover, the cable gland incorporates a dual safety arrangement to resist accidental cable pulling.
Installation Options
The Zenit DG steel Pump supports free-standing installation in sumps, tanks and compact lifting stations.
Moreover, selected models accept an adjustable float switch for automatic start and stop control. Zenit also offers a vertical-travel level switch for small pits.
Therefore, installers can manage operating levels even where a conventional swinging float has limited space.
Zenit DG steel Applications in India
The DG steel sewage pump may support applications across India such as:
- Domestic sewage lifting
- Residential wastewater stations
- Soiled wastewater containing solids
- Small civil wastewater plants
- Basement wastewater collection
- Compact commercial sewage systems
- Collection tanks and sumps
- Compatible emergency wastewater pumping
Moreover, the stainless-steel construction can suit installations where corrosion resistance and compact size are important.
However, clear or slightly soiled drainage water, seepage water and irrigation duties may require a more suitable clean-water pump.
Operating Conditions
Published steel Series limits 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: 10 m
- Maximum liquid density: 1 kg/dm³
- Maximum starts: 30 per hour
- Maximum acoustic pressure: Below 70 dB
However, users should confirm the exact operating limits for the selected model and liquid.
Selecting the Correct Zenit DG steel Pump
Correct selection depends on:
- Required flow and total head
- Solids size
- Wastewater composition
- Pipe diameter
- Sump dimensions
- Electrical supply
- Single-phase or three-phase requirement
- Discharge size
- Float-switch requirement
Therefore, users should select the Zenit DG steel Pump from model-specific hydraulic data. Otherwise, an unsuitable pump may cycle excessively, clog or fail to provide the required discharge head.
