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 contact against the impeller.
Zenit designed the steel Series for household installations and small civil plants. Consequently, the pump combines corrosion resistance with reliable wastewater lifting.
Stainless-Steel Vortex Hydraulic Design
The Zenit DG steel Pump uses an AISI 304 stainless-steel vortex impeller and an AISI 304 stainless-steel casing. During operation, the impeller creates a swirling flow inside the hydraulic chamber.
As a result, much of the wastewater passes around the impeller instead of through narrow channels. Therefore, the DG steel vortex pump helps reduce clogging when the liquid contains compatible suspended solids.
Main Features and Benefits
- 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 metres
- AISI 431 stainless-steel shaft
- Silicon-carbide/alumina mechanical seal
- Adjustable float-switch options
- Thermal-overload protection
- Maximum immersion depth of 10 metres
Together, these features make the Zenit DG steel Pump suitable for compact sewage lifting and residential wastewater stations.
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 deliver up to approximately 6.7 l/s and develop heads up to 10.1 metres.
However, maximum flow and maximum head occur at different operating points. Therefore, engineers should select the exact model from its hydraulic curve rather than assigning both limits to every pump.
Full Free-Passage Operation
The smallest model provides a 25 mm free passage, while selected larger models provide up to 40 mm. Consequently, the stainless-steel vortex pump can move compatible wastewater solids that may block smaller passages.
Moreover, vortex hydraulics limit direct contact between the impeller and suspended material. Nevertheless, the pump does not grind or cut waste. Therefore, users should prevent wipes, long fibres, stones and metal objects from entering the collection chamber.
Compact Stainless-Steel Construction
Zenit manufactures the casing, impeller and handle from AISI 304 stainless steel. In addition, the integral drive shaft uses AISI 431 stainless steel for high mechanical strength.
Consequently, the Zenit DG steel Pump offers lightweight, corrosion-resistant construction for domestic and small civil installations. The insulated handle also supports convenient transport.
Motor Protection and Cooling
The DG steel wastewater pump uses a dry motor with thermal-overload protection. An integrated cooling jacket controls 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 match the electrical arrangement to the installation.
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 remains in direct contact with the liquid and helps protect the sealing area.
Consequently, the oil chamber supports seal lubrication and service life. Moreover, the cable gland uses a dual safety system to resist accidental cable pulling.
Installation Options for Residential Lifting
The Zenit DG steel Pump supports free-standing use in sumps, tanks and compact lifting stations. Selected models also accept an adjustable float switch for automatic start and stop control.
Moreover, Zenit offers a vertical-travel level switch for small pits. Therefore, installers can manage operating levels where a conventional swinging float lacks sufficient space.
Operating Limits
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 metres
- Maximum liquid density: 1 kg/dm³
- Maximum starts: 30 per hour
- Maximum acoustic pressure: Below 70 dB
However, users should confirm the exact model, liquid composition and electrical supply before installation.
Sewage and Wastewater Applications
The Zenit DG steel sewage pump suits:
- Domestic sewage lifting
- Soiled wastewater containing solids
- Residential lifting stations
- Small civil wastewater plants
- Basement wastewater collection
- Compact commercial sewage systems
- Emergency pumping in compatible conditions
- Collection tanks and sumps
However, Zenit positions the related DR steel pump for clear or slightly soiled water, seepage water, wells, tanks and garden sprinklers. Therefore, users should not market DG steel primarily as a clean-water drainage pump.
Choosing the Correct DG steel Model
Correct selection depends on required flow, total head, solids size, pipe diameter and sump arrangement.
In addition, users should confirm the power supply, phase, discharge size and float-switch requirement. Therefore, specialists should select the Zenit DG steel Pump from model-specific hydraulic data.
Otherwise, an unsuitable model may cycle excessively, clog or fail to provide the required discharge head.
