All Stainless Steel Submersible Sewage Pump WQD/WQ Series | Meibao Pump | Threaded-Máy bơm Meibao Nhà sản xuất máy bơm chống ăn mòn lớn nhất Trung Quốc Từ năm 2016

Product Dewspiption

The Meibao WQD/WQ Series all stainless steel submersible sewage pump is engineered for reliable and efficient handling of wastewater, sewage, and corrosive liquids. Featuring a precision-cast stainless steel (SUS304) shell, this series offers exceptional corrosion resistance, high head, and large flow capabilities . The threaded connection design facilitates easy installation. With a unique single or dual-channel impeller structure, these pumps can pass fibers up to 5 times the pump diameter and solid particles up to 50% of the outlet diameter . Equipped with F-class insulation, thermal overload protection, and double mechanical seals, the WQD/WQ series ensures long service life and safe operation in demanding environments.

All Stainless Steel Construction

Precision-cast stainless steel (SUS304/SUS316) shell provides excellent corrosion resistance, environmental protection, and durability for handling aggressive wastewater.

Anti-Clogging Impeller Design
Unique single or double-channel impeller structure enables high solids passage capacity, handling fibers up to 5× the pump diameter and solids up to 50% of the outlet size.

Robust Sealing System

Double fluororubber mechanical seals in the oil chamber and single-sided seal in the outer chamber effectively protect the motor from water ingress and shaft friction damage.

Motor Protection

High-temperature motor windings with F-class insulation and built-in thermal overload protector prevent motor burnout from overheating or overcurrent.

Versatile Configuration Options

Optional mixing device for sludge suspension, cutting device for fibrous debris (plastic, paper, straw), and customized corrosion-resistant cables/PTFE seals for special requirements .

Typical Applications

Building & Residential: Sewage and wastewater discharge from residential complexes, hotels, and hospitals.

Municipal Engineering: Municipal sewage treatment plant drainage systems and pumping stations.

Industrial Drainage: Factory wastewater and effluent transfer, including general corrosive media containing solid particles.

Construction Sites: Dewatering of pits, trenches, and foundations.
