Description
WE 5020-42 – submersible sewage pump
The IPRO WE 5020-42 submersible pump is a professional device with a two-channel closed impeller, designed for pumping dirty water and domestic wastewater containing small solid contaminants. Wide flow channels and double mechanical sealing ensure high operating reliability, even under demanding conditions in sewage pumping stations.
Who is it for?
- Operators of sewage pumping stations and small treatment plants – high capacity and head allow it to serve demanding facilities and housing estates.
- Farms and livestock holdings – the pump handles the drainage of dirty water, rainwater, and surface water from ditches and tanks.
- Construction and service companies – its simple design and easy disassembly make the pump convenient for dewatering excavations and carrying out routine maintenance work.
- Irrigation system installers – wide impeller channels make it easier to select the pump for extensive irrigation systems for green areas.
Applications
The WE 5020-42 submersible pump is designed for pumping dirty water and domestic wastewater containing small solid contaminants. It is suitable for household and residential sewage pumping stations, irrigation systems, groundwater drainage, and fountain operation. The two-channel closed impeller allows the pump to handle liquids containing solid particles or fibers with a length not exceeding 80% of the pump’s 21 mm free passage diameter.
The WE 5020-42 400V submersible pump is particularly well suited to applications requiring high capacity with moderate contamination of the pumped medium, such as farms, excavation dewatering on construction sites, or small sewage treatment plants.
The pump is not a water treatment device – when using it for other purposes, we recommend ensuring appropriate preparation.
WE 5020-42 features – description and technical data
The motor and pump housing, impeller, and oil chamber are made of ŻL200 gray cast iron, making the construction resistant to abrasion and impacts typical of operation in a heavily contaminated sewage environment. The pump shaft and fasteners are made of stainless steel, ensuring corrosion resistance during prolonged contact with moisture and wastewater. Double mechanical sealing (upper SiC/graphite, lower SiC/SiC) effectively protects the motor chamber against liquid ingress, even under difficult operating conditions.
The motor operates with class F insulation and is protected by thermal protection built into the winding. In addition, two independent moisture sensors – in the oil chamber and motor chamber – signal any water ingress before drive failure occurs. The two-channel closed impeller has wide flow channels that are difficult to block even when solid contaminants are present, while an innovative mixing system that agitates sediment around the pump inlet enables more effective suction of accumulated solid fractions.

Frequently asked questions (FAQ) – WE 5020-42 submersible pump
What is the WE 5020-42 pump designed for?
The IPRO WE 5020-42 submersible pump is designed for pumping dirty water and domestic wastewater containing small solid contaminants, without abrasive or highly corrosive particles. It is suitable for sewage pumping stations, irrigation systems, and excavation dewatering.
Will the WE 5020-42 pump work in my installation?
The pump is suitable for installations in which the pumped liquid is clear, non-aggressive, and does not contain solid particles or fibers exceeding 80% of the 21 mm free passage diameter. When selecting a pump for a specific installation, it is worth comparing the required head and capacity with the parameters provided in the product data sheet. If in doubt, contact the technical department.
Can the WE 5020-42 pump operate continuously?
Yes, the pump is designed for permissible continuous operation when fully submerged in liquid, allowing it to operate continuously in pumping stations without the need for regular breaks.
How is the pump motor protected against damage?
The motor is protected by thermal protection built into the stator winding and two independent moisture sensors – in the oil chamber and motor chamber – which signal any water ingress before drive failure occurs.
What is included with the WE 5020-42 set?
The pump comes with a DN50H coupling foot, a pump hook, and a guide-rail bracket, enabling stationary installation in a pumping station without the need to purchase additional equipment.
Where can I buy the WE 5020-42 submersible pump?
Dambat does not sell directly. The WE 5020-42 pump is available from commercial partners, installation wholesalers, and authorized online distributors.
