Self-priming sewage pump

Self-priming sewage pump

Product Introduction

1. The ZW self-priming sewage pump, a novel product developed through extensive research into similar domestic and international technologies, combines self-priming with non-clogging sewage discharge. It utilizes a hybrid axial recirculation system, with the pump body providing a unique impeller flow path design. Unlike conventional self-priming clean water pumps, it eliminates the need for a foot valve or water inlet, yet can also dissolve large solid particles and long fibers.
2. It is widely used in municipal sewage projects, pond and aquaculture manure treatment, waste sedimentation, and as a pump for handling impurities in chemical media such as light industry, papermaking, food, chemicals, pharmaceuticals, power generation, slurries, and mixtures.
3. Compared to similar domestic products, this pump features a simple structure, excellent self-priming performance (with a self-priming height of up to 5 meters), strong discharge capacity, high efficiency and energy saving, and easy maintenance (it can completely replace WQ/QW submersible sewage pumps). This is a domestic first among sewage pumps. Its technical indicators lead the country and reach international advanced levels, offering broad market development prospects.

Core Advantages

1.Fully Electric Protection
Prevents impacts during production and protects the stator coils
2.High-performance design, no burnout
Built-in overload protection and phase loss protection prevent burnout
3.Long-lasting durability
Long bearing life, low noise, and energy savings
4.Excellent heat dissipation
Full contact between the core and the casing ensures excellent heat dissipation and low operating temperature rise.

Applications

Suitable for industrial and urban water supply and drainage, high-rise building pressure boosting, garden sprinkler irrigation, fire protection, long-distance transportation, HVAC/refrigeration cycles, bathroom heating and cooling water circulation boosting, and equipment support.
