Description
ZWE 50-32 – submersible sewage pump with cutting impeller
The IPRO ZWE 50-32 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, enabling safe operation even when the pumped medium.
Who it is 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 the drainage of domestic wastewater, dirty water, and rainwater and surface water.
- Construction and service companies – the simple design and easy disassembly facilitate using the pump for excavation dewatering and routine maintenance work.
- Irrigation system installers – the cutting system’s high resistance to abrasion and corrosion is ideal for extensive green-area irrigation installations.
Applications
The ZWE 50-32 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 and draining dirty water and sewage domestic wastewater systems, irrigation systems, or excavation dewatering.
Due to the design of its cutting impeller, the ZWE 50-32 pump is not intended for media that is highly corrosive media or media containing abrasive or corrosive particles. The ZWE 50-32 submersible pump The 400V model performs well wherever the pumped medium contains solid contaminants requiring size reduction before pumping, e.g. in sewage pumping stations, farms, or on construction sites for excavating dewatering.
The pump is not a water treatment device—if it is used for other purposes, we recommend ensuring adequate preparation.
ZWE 50-32 features – description and technical specifications
The motor and pump body, impeller, and oil chamber are made of ŻL200 gray cast iron, making making the construction resistant to abrasion and impacts typical of operation in highly a contaminated sewage environment. 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 The cutting system is highly resistant to abrasion, even in aggressive environments.
The motor operates in insulation class F and is protected by a built-in thermal protection system in the stator winding, plus two independent humidity sensors—in the oil chamber and in the motor chamber, signaling 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) – IPRO ZWE 50-32 submersible pump
What is the ZWE 50-32 pump designed for?
The IPRO ZWE 50-32 submersible pump is designed for raw sewage and liquids containing solid or fibrous particles no longer than 80% of the pump outlet diameter. It is suitable for sewage 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, whereas the WE pump has a closed two-channel impeller without cutting cutting impeller. This makes the ZWE suitable for sewage containing a higher amount of solid solids than the WE series.
Can the ZWE 50-32 pump operate continuously?
Yes, the pump is designed for permissible continuous operation when fully submerged in liquid, which allows continuous operation in pumping stations without the need for regular interruptions.
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 indicate any water ingress before the drive fails.
What is included with the ZWE 50-32 set?
The pump comes with a coupling foot, pump hook, and bracket guide rails, enabling stationary installation in a pumping station without the need to purchase additional accessories.
Where can I buy the ZWE 50-32 submersible pump?
Dambat does not sell directly. The ZWE 50-32 pump is available from partners retail outlets, installation wholesalers, and authorized online distributors.
