Sewage Ejector Pumps

With increasingly limited urban land, the continuous expansion and development of cities force people to move underground. Consequently, the wastewater discharge from buildings has become a major issue affecting people's lives. The existing underground wastewater discharge facilities, due to outdated technology and equipment, have high failure rates and require regular cleaning and maintenance by professionals. This not only causes significant pollution to the equipment in underground buildings but also fails to meet the growing demands of development.

This series of equipment achieves sealed discharge of wastewater, solving secondary pollution during the discharge of wastewater in underground buildings. It employs a separation technology for wastewater and debris, ensuring the entire unit requires no cleaning during operation. Additionally, this series boasts a low maintenance rate, making it the optimal choice for eliminating secondary environmental pollution from wastewater discharge in underground structures in modern society.

1. Installation Method: Subterranean and ground-level installation; Integrated equipment features 2 pumps, operating alternately with each other as backup.

2. Level Control Method: Float switch used

3. Export Forms: Vertical, Flange Interface

4. Non-Clogging: Equipped with a solid-liquid separator, the pump impeller does not come into contact with debris, preventing entanglement and clogging, thereby extending its service life.

5. Non-polluting: The tank features a fully-sealed, movable lid design, allowing for sealed storage and discharge of wastewater, preventing overflow and odor.

6. Sediment-Free and No Draining Required: Features a unique backwashing device that can effectively rinse away sediment in the water tank at any time, ensuring the tank remains automatically clean with no sediment buildup, eliminating the need for regular draining.

7. Control Method: Liquid level float ball automatic control with over-limit water level audio-visual alarm function, manual/automatic operation feature.

8. Equipment Configuration: Includes the housing, pump, inlet and outlet pipes, solid-liquid separation device, rubber sealing strips, fasteners, emergency drain valve, outlet pipe and pipe fittings, spherical check valve (cast iron), control box, base, and accessories. The equipment's inlet and drain pipes are connected using flanged joints.

9. The equipment water tank is made of 2.0mm thick 304 stainless steel, with a lid featuring a handle and a clasp for easy inspection and maintenance.

10. Control System: Main components in the intelligent control box are from Schneider, the cabinet is made of stainless steel 201 material.

11. Equipment Assembly Requirements: Welded parts and焊接安装 sections should be sturdy, smooth, and aesthetically pleasing, free of defects such as false welding or gaps. Weld slag and flux should be cleaned thoroughly. All connection points must be secure and reliable with no loose fasteners. The arrangement of pipes, electrical components, and wiring should be neat and reasonable.
