Description
ZWE 50-12 – submersible sewage pump with cutting impeller
The IPRO ZWE 50-12 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 grinds contaminants at the pump inlet, allowing safe operation even when the pumped medium is heavily contaminated. 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 pump blockage.
- Farms and livestock operations – the pump handles domestic wastewater, dirty water, and rainwater and surface water discharge.
- Construction and maintenance companies – the simple design and easy disassembly make the pump convenient for excavation drainage and ongoing maintenance work.
- Irrigation system installers – the grinding system's high resistance to abrasion and corrosion is ideal for extensive green-area irrigation installations.
Applications
The ZWE 50-12 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 sewage, domestic wastewater systems, irrigation systems, and excavation drainage.
Due to the design of its cutting impeller, the ZWE 50-12 pump is not intended for media that are highly corrosive media or media containing abrasive or corrosive particles. The ZWE 50-12 submersible pump 400V works well where the pumped medium contains solid contaminants requiring grinding before pumping, e.g. in sewage pumping stations, farms, or on construction sites for excavating drainage.
The pump is not a water-treatment device—if it is used for other purposes, we recommend ensuring appropriate preparation.
ZWE 50-12 features – description and technical data
The motor and pump housing, impeller, and oil chamber are made of ŻL200 gray cast iron, making the construction making the construction resistant to abrasion and impacts typical of operation in heavily 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 of the grinding system, even in aggressive environments.
The motor operates in insulation class F and is protected by a built-in thermal protection device in the stator winding; additionally, two independent humidity sensors—in the oil chamber and in the motor chamber, signaling any water ingress before a failure occurs drive. The unique design of the cutting disc with grooves and a scraper effectively removes shredded solids, preventing them from accumulating on the impeller.

Frequently Asked Questions (FAQ) – IPRO ZWE 50-12 submersible pump
What is the ZWE 50-12 pump intended for?
The IPRO ZWE 50-12 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 trench dewatering.
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, whereas the WE pump has a closed two-channel impeller without cutting cutting impeller. This makes the ZWE suitable for wastewater with a higher amount of solid solids than the WE series.
Can the ZWE 50-12 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 possible water ingress before drive failure occurs.
What is included with the ZWE 50-12 set?
The pump comes with a coupling foot, a pump hook, and a support bracket for the guide rails, allowing stationary installation in a pumping station without the need to purchase additional equipment.
Where can the ZWE 50-12 submersible pump be purchased?
Dambat does not sell directly. The ZWE 50-12 pump is available from partners retailers, plumbing wholesalers, and authorized online distributors.
What are the warranty terms for the ZWE 50-12 pump?
IPRO – 36 months (3 years) manufacturer's warranty. Warranty and post-warranty service provided by Dambat.
