Shanghai Tengdao ZW Series Diesel Engine Non-Blocking Self-Priming Sewage Pump
Introduction
The Shanghai Tengdao ZW Series Diesel Engine Non-Blocking Self-Priming Sewage Pump represents a significant advancement in the field of wastewater management. With a flow range of 100 to 1000 m³/h and a head range of 10 to 80 meters, this pump is specifically designed to handle the challenges associated with sewage and wastewater applications.
Overview of Features
The ZW Series pump is engineered to combine self-priming and non-blocking features into a single unit. Utilizing an axial flow return design, the pump can operate like a standard self-priming clean water pump without the need for a bottom valve or priming water. This innovative design allows it to effectively 
handle large solid particles and long fiber impurities, making it ideal for diverse applications.
handle large solid particles and long fiber impurities, making it ideal for diverse applications.1. **Flow and Head Capacities**: The ZW Series offers an impressive flow capacity ranging from 100 to 1000 m³/h and a head capacity between 10 to 80 meters, making it suitable for various operational demands.
2. **Power Compatibility**: With a power range of 1 to 100 kW, the pump can be matched with engines from reputable manufacturers, providing flexibility in terms of power selection.
3. **Wide Caliber Range**: The pump features a caliber range from 25 mm to 300 mm, allowing it to cater to different installation requirements and fluid handling scenarios.
Design and Construction
The ZW Series pump is characterized by its robust and straightforward structure, which offers several benefits:
– **Mechanical Seal**: The pump incorporates a new type of friction pair for the mechanical seal that operates in a lubricated chamber, extending the service life and reducing maintenance needs.
– **Compact Structure**: The compact design minimizes noise and facilitates easy maintenance, allowing users to perform repairs without extensive downtime.
– **Automatic Control Panel**: The pump is equipped with an automatic control system that adjusts the operation based on liquid level changes, eliminating the need for constant supervision and enhancing operational convenience.
Application Areas
The ZW Series Non-Blocking Self-Priming Sewage Pump is versatile and widely applicable across numerous industries:
– **Municipal Sewage Engineering**: Effectively manages municipal wastewater treatment processes.– **Aquaculture Waste Management**: Handles sewage generated from river and pond aquaculture activities.
– **Mining and Industrial Applications**: Efficiently removes sediment and impurities from waste mineral deposits.
– **Light Industry and Food Processing**: Suitable for applications in the food, chemical, and pharmaceutical industries, where quality control is paramount.
Operational Conditions
To ensure optimal performance, the ZW Series pump operates under specific conditions:
1. **Temperature Limits**: The ambient temperature should not exceed 50°C, while the medium temperature can reach up to 80°C; special requirements can allow for temperatures up to 200°C.
2. **Density Constraints**: The medium density should not exceed 1240 kg/m³.
3. **Self-Priming Capacity**: The self-priming height is restricted to 4.5 to 5.5 meters, with the suction pipe length limited to 10 meters.
4. **Solid Handling Capability**: The pump can accommodate suspended particles with a diameter up to 60% of the pump’s diameter, and fibers up to five times the pump diameter.
With its ability to manage solid waste effectively, ease of maintenance, and energy-efficient operation, the ZW Series pump stands out as a premier choice for those seeking reliability and efficiency in sewage management.
