ZW Self-Priming Sewage Pump is a self-priming pump that combines self-priming capabilities with non-clogging sewage discharge features. It boasts simple structure, excellent self-priming performance, strong sewage discharge capacity, and effective energy savings. This pump was successfully developed after extensive research on similar products both domestically and internationally. Its unique design of the impeller and pump body achieves both self-priming and non-clogging sewage discharge functions.
Technical Specifications
The ZW self-priming sewage pump typically has a flow rate range of 5-800 cubic meters per hour (m³/h), a head range of 12-80 meters (m), an electric motor power range from 1.5 kW to 55 kW, a speed range of 1450-2900 rotations per minute (r/min), and an inlet and outlet diameter range of φ25 to φ300 millimeters (mm). The self-priming height is generally 4.5 to 5.5 meters (m), and the medium temperature usually does not exceed 100°C, but can reach higher temperatures under special circumstances.
Application Fields
ZW Self-Priming Sewage Pumps are widely used in various fields, including agricultural irrigation, wastewater treatment, construction, building equipment, light industry, etc. They are particularly suitable for handling liquids containing large particle solids and long fiber impurities, such as pond aquaculture, light industry, papermaking, textiles, food, and chemicals. Additionally, these pumps play a crucial role in power, mining, petrochemical, and steel industries, especially excelling in treating wastewater containing solid-liquid mixtures.
Maintain and service
ZW Self-Priming Sewage Pumps feature high-quality mechanical sealings, effectively preventing fluid leakage and reducing the risk of pollution caused by leaks. Their design is simple, with ease of use, movement, installation, and maintenance, and stable performance.
