Introduce the basic functions of the product
The main functions of the sealless self-priming pump include strong self-priming ability, stable operation, no wear on the sealing device, long service life, low vibration, low noise, flexible movement, easy disassembly, easy installation, no need for anchoring, etc.
Introduce the basic situation of the product
The sealless self-priming pump is a new type of pump with reliable sealing and no leakage. It uses a leak-free sealing device to replace the packing seal and mechanical seal of the traditional water pump, solving the "running, bubbling, dripping and leaking" problems of the traditional seal. The sealing device has no friction and wear during operation, and its service life is more than 10 times longer than that of traditional products.
Usage Environment
WFB seal-free, leak-free, self-priming pump has compact structure, beautiful appearance, small size, low noise, reliable operation, and convenient use and maintenance. It can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photography, scientific research institutions, national defense industry and other units to pump acid, alkali, oil, rare and precious liquid, poison, volatile liquid, as well as supporting circulating water equipment and filter. Especially for the pumping of leaky, flammable and explosive liquids, this pump is more ideal.
Product Advantages
Heavy-Duty Sealless Self-Priming Pump – For Oil, Water & Aggressive Fluids
Corrosion resistance, high temperature and high pressure resistance, stable self-priming performance, leak-free design, long life, low noise and low vibration
Product Features
1. The "pump-type multi-faceted centrifugal seal device" is adopted, which eliminates the packing seal, packing seal and mechanical seal of the traditional water pump, and completely overcomes the "escape, bubbling, dripping and leakage". It is the most ideal equipment to replace various long-axis submersible pumps, submersible pumps, submersible sewage pumps, etc.
2. The sealing device does not rub or wear during operation, and its service life is more than 10 times longer than similar products.
3. The principle of the vacuum pump is transplanted, and the self-priming performance is stable and reliable. In particular, the "electric air control valve" is adopted, which truly realizes "one-time drainage, lifelong self-priming".
4. Small vibration, low noise, flexible movement, easy disassembly, easy installation, and no need for anchor fixation.
5. It has excellent self-control function and can be used in conjunction with high-tech fields and highly automated systems.
6. No anchor is required, and the installation is extremely convenient.

Product Usage
It can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film and photography, scientific research institutions, national defense industry and other units to pump acid, alkali, oil, rare and precious liquid, poison, volatile liquid, as well as supporting circulating water equipment and filter. Especially for the pumping of leaky, flammable and explosive liquids, this pump is more ideal.
Product Operation Guid
1. After installation, the inlet should be filled with liquid medium to ensure that the pump body can be drained once and no further drainage is required. Please tighten the inlet cap to prevent air leakage from affecting the self-priming function.
2. Install the buffer plate structure filter at the bottom of the suction port to prevent excessive particles from being sucked into the pump body, damaging the pump body and affecting the self-priming performance.
3. When pumping a medium containing concentrated sulfuric acid, do not use water for drainage to prevent harm to the human body and damage to mechanical equipment.
4. Before starting the self-priming pump, check whether the pump shaft is flexible. You can check whether the running direction is consistent with the steering mark by jogging.
5. Do not support the weight of the suction pipe and the discharge pipe on the outlet flange of the unsealed self-priming pump. They should be fixed on the support frame, which needs to be purchased by the user. Ensure that the pipes are tightly connected to avoid air leakage affecting the performance of the pump body. 6. When pumping a medium containing sediment or crystals, if the pump is stopped for a long time, the accumulated liquid in the pump should be discharged from the outlet to avoid sediment or crystals remaining in the pump cavity, which may damage the pump body when it is started again. When using again, the drainage steps should be repeated.
Frequently asked questions
1. Leakage at the connection between the connecting pipe and the pump
The water pump cannot form a vacuum and does not absorb liquid. The solution is to check and repair the connection and replace the sealing gasket.
2. The connection between the motor and the water pump leaks at the moment of starting
The reason is that the working pressure exceeds the specified parameters of the pump. The solution is to reduce the working pressure, or open the outlet valve before starting, and slowly close it after it runs normally.
3. Flow rate and head are not up to standard
The reasons include too little liquid in the container or liquid pool, motor reversal, air leakage at the suction end, clogged bottom filter, low voltage, etc. The solution is to check and eliminate these reasons one by one.
4. Some pistons of the electric air control valve are not sealed.
The reason may be that the cable and the motor terminal are in poor contact or the fuse is damaged. The solution is to check and turn on the power supply, or add oil lubrication.
