Video Introduction

Function

1. Non-clogging Design

Features a large-passage impeller and volute casing, enabling efficient handling of high-viscosity media containing solid particles, fibers, and sludge. It accommodates particle diameters up to 50mm, effectively eliminating the clogging issues common in traditional sewage pumps.

2. High-Efficiency Self-Priming Capability

Automatically generates a vacuum after the initial priming; offers a self-priming lift of 5–8 meters (depending on the model). Eliminates the need for foot valves or priming devices, allowing for rapid startup in emergency drainage situations.

3. Corrosion and Wear Resistance

Flow-path components are available in cast iron or stainless steel (304/316L), with impellers treated with wear-resistant alloy coatings. Suitable for handling corrosive media such as chemical wastewater and seawater.

4. Energy Efficiency and Low Consumption

Optimized hydraulic design improves efficiency by 15–20% compared to standard sewage pumps. Equipped with motors meeting IE3 energy efficiency standards, ensuring lower long-term operating costs.

5. Intelligent Protection Features

Select models feature dry-run protection and overload alarms. Motors are rated Class F insulation with an IP68 waterproof design, ensuring reliability in harsh operating conditions.

6. Versatile Applications

Covers a flow rate range of 5–100 m³/h and supports both stationary and mobile installations. Widely used in municipal pipe networks, construction excavation sites, aquaculture farms, industrial parks, and more.
