Cast iron/Stainless steelDirect-coupled Self-priming Sewage Pump
Self-priming and non-clogging sewage discharge features are integrated into this pump. It uses an axial reflux external mixing system and has distinctive impeller flow channel and pump body structural designs. In addition to being able to suction and discharge liquids that contain large solid particles and long-fiber contaminants, it can function similarly to a typical self-priming clean water pump without the need for a bottom valve or priming water. It is the best impurity pump for handling chemical media in light industry, papermaking, textiles, food processing, chemical engineering, electrical industries, fibers, slurries, and mixed suspensions. It is also extensively used for municipal sewage projects and pond aquaculture.
Product Advantages
The ZWL pump handles wastewater that contains particles and fibers by combining self-suction functionality. Fast self-priming without bond valves or manual filling is made possible by its axial reflow architecture. The motor guarantees strong performance with minimal vibration and noise when connected directly to broad flow channels and adjusted impedance. It is corrosive and chemically resistant to harsh environments since it is made of sturdy cast iron or corrosion-resistant materials. This little pump can be used for both industrial and municipal wastewater. Perfect for chemical processing and aquaculture, with simple installation and minimal upkeep ZWL offers dependable fluid transfer that optimizes efficiency in a range of applications and concurrent running expenses.
Structural Diagram
| 1 | Motor | Directly connected to the water pump for power transmission, using a branded motor. |
| 2 | Pump Shaft | Coaxial with the motor. It is an extended motor shaft, ensuring concentricity for smooth pump operation, noiseless and vibration-free. Chrome-plated for enhanced durability. |
| 3 | Water Retaining Ring | Prevents water leakage into the motor due to seal failure. |
| 4 | Mechanical Seal | Made of stainless steel, tungsten carbide, fluorine rubber, etc. Balanced design resistant to high temperature and pressure, long service life, leak-free, no shaft wear, no scale buildup, ensuring a clean working environment. |
| 5 | Pump Cover | Connects the pump body and the motor. |
| 6 | Pump Body | Designed with an excellent hydraulic model for the pressure chamber, suction chamber, and gas-liquid separation chamber, combining aesthetics and efficiency. Features mounting feet for easy installation and stable operation. |
| 7 | Impeller | Designed using advanced hydraulic models, typically available in single-channel and dual-channel types, offering high efficiency, excellent flow capacity, and reliability. |
| 8 | Seal Ring | Seals the joint between the pump impeller and the pump body. |
| 9 | Drain Plug | Allows draining of stored liquid when the pump is not in use for extended periods. |
| 10 | Bottom Cover Plate | Can be opened to remove accumulated sediment or debris from the pump body. |
| 11 | Base Plate | Connects the entire pump for easy installation and can also accommodate vibration isolators. |
| 12 | Gas-Liquid Separation Tube | During pump startup, air is expelled through this tube, and water is recirculated to complete the self-priming process. |
| 13 | Outlet Pipe | Connects to the discharge pipeline. |
| 14 | Water Fill Valve | Can be opened to add water when the internal cavity of the pump lacks sufficient liquid. |
| 15 | Check Valve Plate | Prevents backflow of water from the pipeline when the pump stops working. |
| 16 | Inlet Pipe | Connects to the inlet pipeline. |
