Application fields of PW type horizontal sewage discharge pump 1、 Municipal sewage treatment and upgrading Small and medium-sized sewage pump station: When the pump station adopts a dry pump room (with the motor and pump body installed dry on the ground), the PW pump is used to lift the grid filtered sewage to the subsequent treatment unit. Its horizontal structure is convenient for maintaining the impeller and seal, without the need for overall lifting. Rainwater pumping station drainage: pumping out mixed leaves, sediment, and surface runoff debris in rainwater. PW pumps can pass solid particles with appropriate diameters (such as 2.5-inch impellers that can accommodate 35-50mm particles) and are not easily clogged. 2、 Industrial wastewater treatment system Factory workshop wastewater: applicable to wastewater containing impurities such as short fibers, broken skin, blood clots, and fruit peels discharged from industries such as printing and dyeing, papermaking, leather, slaughtering, and food processing. The pump body and impeller can be made of cast iron or corrosion- resistant material (304/316 stainless steel). Neutralization sedimentation tank effluent from chemical and pharmaceutical factories: Extract wastewater containing suspended solids and chemical sludge, and send it to a filter press or concentration tank. The turbid circulating water system in the steel and mining industries: transporting circulating water or sewage containing iron oxide scale, coal powder, sand and gravel. 3、 Construction sites and temporary drainage Excavation dewatering: Extracting underground seepage, rainwater, and water containing mud and sand. PW pumps can work continuously and have better resistance to sediment wear than ordinary water pumps. Tunnel construction drainage: When there is no risk of flooding inside the tunnel but it is necessary to pump the water from the tunnel area outside, a ground mounted PW pump can be used. Temporary sewage discharge: such as connecting temporary pipelines as mobile sewage equipment during the renovation of old pumping stations. 4、 Agricultural Irrigation and Aquaculture Drainage in flood prone areas: Remove the accumulated water in farmland and extract muddy water containing a small amount of weeds and soil.

self-priming pump is a modified type of centrifugal pump, differing from conventional centrifugal pumps that require manual priming and air venting before startup. With its built-in liquid reservoir due to its structural design, the self- priming pump eliminates the need for repeated water filling after the initial priming. It can automatically draw liquid from below the pump's installation position, preventing air binding. This type of pump is widely used in scenarios such as water supply and drainage, garden irrigation, sewage lifting, chemical dosing, and on-site pumping, where low-position pump installation or frequent start-stop cycles are impractical. 2、 Working principle 1. First use: Add water intake Fill the storage chamber of the pump body with liquid and close the exhaust port before the first operation, leaving a certain amount of working fluid in the storage chamber. 2. Gas liquid mixture suction stage The impeller rotates at high speed, throwing the water retained in the pump body towards the volute, creating negative pressure at the impeller inlet; The air in the suction pipeline mixes with the water in the pump at high speed, forming a mixture of gas and water, which is continuously pressed towards the gas-liquid separation chamber. 3. Gas liquid separation The gas water mixture enters the upper part of the separation chamber, and the gas with low density is discharged from the exhaust port. The liquid falls back to the lower storage chamber of the pump by gravity to participate in gas-liquid mixing circulation. 4. Normal water delivery As the air inside the pipeline is continuously emptied, a vacuum is formed in the suction pipeline, and the liquid level is continuously sucked into the pump under atmospheric pressure. The self-priming process is completed, and the pump enters the conventional centrifugal pump water delivery condition. Core feature: After the first addition of water, sealing water will remain inside the pump casing, and there is no need to refill the pump again after subsequent shutdown and restart. 3、 Main structure Self suction pump body (with gas-liquid separation storage chamber): Different from ordinary centrifugal pump volutes, the upper part is designed with a large capacity air-water separation chamber to store water and separate air; Impeller: mostly closed impeller (for clean water self-priming pumps), open/double channel impeller (for sewage self-priming pumps); Check valve (bottom valve/one-way valve inside the pump): Lock the water storage inside the pump after shutdown to prevent water from flowing back into the suction tank, ensuring that it can still self suction next time; Exhaust plug and water inlet: add water for the first time and empty the air inside the pump; Mechanical seal, motor, base. 4、 Main classification 1. According to the conveying medium Clean water self-priming pump Made of cast iron/stainless steel material, with a closed impeller, used for boosting tap water, irrigating farmland, and circulating water supply. It can only transport clean water and cannot contain a large amount of fiber sediment. Non clogging sewage self-priming pump Double channel/cutting impeller, can transport domestic sewage, mild sludge, and wastewater containing a small amount of fiber, mostly used for construction site sewage discharge and small-scale sewage treatment plants. Corrosion resistant self-priming pump (fluoroplastic/stainless steel) Transporting acid and alkali, chemical waste liquid, and electroplating wastewater, mostly used for environmental protection dosing and chemical liquid transportation. 2. According to the structural form Horizontal self-priming centrifugal pump (ZX, ZW type): commonly used in industry, with stable self-priming and a wide range of head and flow rate; Vertical self-priming pump: small footprint, directly connected pipeline installation; Household small self-priming booster pump: 220V single-phase, used for boosting household tap water and taking well water. 3. Follow the self-priming method Internal mixing self-priming pump: gas-liquid mixing occurs inside the impeller, with fast self-priming speed and a self-priming height of generally 4-6m; External hybrid self-priming pump: Gas and liquid are mixed on the outside of the impeller, with a simple and durable structure, commonly used in high flow conditions. 5、 Core performance parameters Self suction height: the most critical parameter, the rated self-priming height of a conventional self-priming pump is 4-6 meters (it is recommended not to exceed 5 meters in practice), which refers to the maximum vertical height from the center of the pump to the suction liquid level; Flow rate, head, rated power voltage; Self suction time: Generally completed within 30-120 seconds, exceeding the time indicates air leakage or water loss; Medium temperature: conventional 0-80 ℃. 6、 Advantages One time water filling, multiple start and stop without filling the pump, solves the problem of frequent pumping of ordinary centrifugal pumps, and eliminates the problem of gas binding and inability to suck water; Flexible installation, can be installed on the ground or at high places, without the need to place the pump below the liquid level or build a pump room; It can suck liquids containing a small amount of gas, and the pipeline can still work normally even with slight air intake; Easy to maintain, highly versatile, with multiple working conditions to choose from for clean water, sewage, and chemical anti-corrosion.

magnetic drive pump is an industrial pump that utilizes magnetic coupling to transmit power and achieve fully sealed, leak-free transportation, making it particularly suitable for handling toxic, flammable, or highly corrosive liquids. It operates by driving the impeller rotation through the magnetic interaction between internal and external magnetic rotors, completely eliminating the physical shaft seal of traditional pumps and fundamentally eliminating the risk of medium leakage The core of the magnetic drive pump lies in the "magnetic coupler," which transmits the rotational power of the motor to the pump shaft without contact. The specific structure includes the following key components: Magnetic Coupling System: Consists of an outer magnetic rotor (connected to the motor) and an inner magnetic rotor (connected to the impeller), completely separated by an isolation sleeve in the middle. Isolation Sleeve: This is the key component for achieving zero leakage, typically made of stainless steel, titanium alloy, or high-performance plastic, ensuring the medium is sealed within the pump chamber. Magnetic steel material: High-performance magnetic pumps often use neodymium iron boron or samarium cobalt permanent magnet materials. Samarium cobalt magnetic steel has better temperature resistance and is suitable for high-temperature working conditions. Cooling and Lubrication: During pump operation, 2%-3% of the conveyed medium's flow rate must be utilized to cool the bearing and magnetic rotor areas, hence no idling is permitted. Structural Forms: Common configurations include horizontal, vertical, and high- temperature resistant types. Some high-temperature models are equipped with water cooling devices or double-layer insulation structures to prevent heat conduction to the motor and avoid demagnetization. Performance range Normal temperature pump is used for fluids with temperature from -30 ℃ to 120 ℃.
