Description
ZWE 50-22 – submersible sewage pump with cutting impeller
The IPRO ZWE 50-22 submersible pump is a professional device with a cutting impeller, designed for pumping raw sewage and liquids containing solid or fibrous. The high-quality hardened-steel impeller effectively shreds contaminants at the pump inlet, allowing safe operation even with heavily contaminated pumped medium.
Who is it for
- Managers of sewage pumping stations and treatment plants – the cutting impeller enables handling sewage containing solid contaminants without the risk of clogging the pump.
- Farms and livestock holdings – the pump handles the discharge of domestic sewage, dirty water, and rainwater and surface water.
- Construction and service companies – the simple design and easy disassembly facilitate using the pump for excavating drainage and routine maintenance work.
- Irrigation system installers – the cutting system’s high resistance to abrasion and corrosion is suitable for extensive green-area irrigation installations.
Applications
The ZWE 50-22 submersible pump is intended for raw sewage and liquids containing solid or fibrous particles no longer than 80% of the pump outlet diameter. It is suitable for supplying raw water, draining dirty water and domestic sewage domestic sewage systems, irrigation systems, and excavating drainage.
Due to the design of its cutting impeller, the ZWE 50-22 pump is not intended for highly highly corrosive media or media containing abrasive or corrosive particles. The ZWE 50-22 submersible pump 400V is well suited to applications where the pumped medium contains solid contaminants requiring cutting before pumping, e.g. in sewage pumping stations, farms, or on construction sites for excavating drainage.
The pump is not a water treatment device – when using it for other purposes, we recommend ensuring proper preparation.
ZWE 50-22 features – description and technical data
The motor and pump housings, impeller, and oil chamber are made of ŻL200 gray cast iron, which makes the construction making the construction resistant to abrasion and impacts typical of operation in highly contaminated sewage environments. The pump shaft and fasteners are made of stainless steel, ensuring corrosion resistance during prolonged contact with moisture and sewage. The impeller and cutting plate are made of hardened steel, ensuring high resistance of the system cutting system against abrasion, even in an aggressive environment.
The motor operates in insulation class F and is protected by a thermal protection device built in in the stator winding, plus two independent humidity sensors – in the oil chamber and in the motor chamber – they signal any water ingress before a failure occurs drive. The unique structure of the cutting disc with grooves and a scraper effectively removes shredded solids, preventing them from accumulating on the impeller.

Frequently asked questions (FAQ) – ZWE 50-22 submersible pump
What is the ZWE 50-22 pump designed for?
The IPRO ZWE 50-22 submersible pump is designed for raw wastewater and liquids containing solid or fibrous particles no longer than 80% of the pump outlet diameter. It is suitable for wastewater pumping stations, irrigation systems, and excavated area drainage.
What is the difference between the ZWE and WE pumps?
The ZWE pump is equipped with a hardened-steel cutting impeller that shreds solids at the pump inlet, while the WE pump has a closed two-channel impeller without cutting elements. This makes the ZWE suitable for wastewater with a higher content of solids than the WE series.
Can the ZWE 50-22 pump operate continuously?
Yes, the pump is designed for permissible continuous operation when fully submerged in liquid, allowing continuous operation 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 humidity sensors—in the oil chamber and motor chamber—that signal any potential water ingress before the drive fails.
What is included with the ZWE 50-22 set?
The pump comes with a coupling foot, pump hook, and guide rail bracket guide rails, enabling stationary installation in a pumping station without the need to purchase additional equipment.
Where can the ZWE 50-22 submersible pump be purchased?
Dambat does not sell directly. The ZWE 50-22 pump is available from partners retail outlets, installation wholesalers, and authorized online distributors.
What warranty conditions apply to the ZWE 50-22 pump?
