WFB vertical unsealed self controlled self-priming pump

Description :

WFB type self controlled self-priming pump is an improved and innovative product that absorbs foreign related products. This product has multiple functions such as temperature and pressure resistance, one-time drainage, and lifelong self-priming. Widely applicable in industries such as electronics, power, chemical, metallurgical, pharmaceutical, food, electroplating, environmental protection, fire protection, water purification, mining, etc., it has received high praise from users.

Supply WFB type vertical stainless steel wear-resistant and corrosion-resistant self-priming pump Performance characteristics WFB type self-priming pump is a type of water pump without sealing design, using a leak free sealing device to replace the packing seal, packing seal, and mechanical seal of the transfer bucket water pump, effectively solving the problems of running, emitting, dripping, and leaking in the transfer bucket sealing method. Its service life is also long. Due to the non friction and wear of the sealing device during operation, the service life of WFB pump is more than 10 times longer than similar products.

The WFB type self controlled self-priming pump adopts a self-priming structure, which can quickly suck liquid into the pump without the need for external liquid filling. This feature enables it to quickly establish liquid circulation during startup, improving work efficiency. WFB pumps are suitable for various liquid media, including corrosive liquids and liquids containing solid particles. Its excellent adaptability enables it to perform excellently in different industrial scenarios. Due to its unsealed design, the WFB pump has a relatively simple structure, reducing the number of failure points, improving equipment reliability and stability, and reducing maintenance difficulty. Especially with the use of electric air control valves, also known as electronic valves, it truly achieves drainage and self-priming. The pump unit has low vibration, low noise, flexible movement, and easy insertion and installation. Equipped with * self-control function, it can be matched with relevant control systems to achieve high automation.

The WFB type self controlled self-priming pump is mainly composed of pump body, impeller, pump cover, guide vanes, secondary impeller, pump shaft, connecting frame, electronic valve and other parts. The pump body is composed of a suction chamber, a liquid storage chamber, and a gas-liquid separation chamber. After the pump is started normally, the impeller sucks in the liquid stored in the suction chamber and the air in the suction pipeline together. The liquid mixed gas is thrown into the gas-liquid separation chamber by the guide vanes under the centrifugal force of the high-speed rotation of the impeller. Due to the sudden decrease in flow velocity, the lighter gas is separated from the mixed liquid and discharged outside the pump. The vaporized liquid re enters the working chamber and mixes with the air sucked in from the suction pipeline inside the impeller. Under the rotation of the impeller, a certain degree of vacuum is quickly formed at the inlet of the pump body, thus achieving the purpose of self-priming.

Its rotational speed is 2900/1450r/min;   The suction diameter is 16~800mm; Flow rate of 0.75~800m3/h;   The medium temperature ranges from -40 ℃ to 180 ℃; Lift range of 5-135 meters;   Self suction depth is between 2.5 and 7 meters; The outlet diameter is 10~600mm; The working pressure is ≤ 1.6Mpa.
