WLW Series Oil-Free Vertical Reciprocating Vacuum Pump

The WLW series oil-free vertical reciprocating vacuum pump is independently developed on the basis of digesting and absorbing foreign technologies. Compared with the W-type horizontal pump, this pump has the following advantages: 1. The wear rate of moving parts is greatly reduced, and the service life of the air valve is significantly improved; 2. The power consumption is reduced by nearly 1/3, the water consumption is reduced by 1/2, and the floor space is reduced by 1/3; 3. The transverse wave deterioration vibration is reduced, and the noise is low; 4. The wear of the cylinder and crosshead is reduced, and the service life of the whole pump is prolonged; 5. The WLW oil-free vacuum pump provides a clean vacuum environment and can be widely used in food, pharmaceutical and industries requiring gas recovery.

Compared with ordinary vertical reciprocating pumps, our company's products have the following advantages:1. The air valve is arranged axially, with high vacuum degree and long service life of the valve plate;2. Adopts a new type of self-lubricating piston ring, which can operate normally without oil and extend the service life of the cylinder;3. The small end of the connecting rod adopts a needle bearing, which greatly improves the service life and reliability;4. The body is designed with a conical shape, and the piston is balanced, making the operation more stable and reliable;5. Unique oil separation structure design ensures pure oil-free effect;6. Can be combined with Roots pump or reciprocating pump to form "Roots-reciprocating" and "reciprocating-reciprocating" high-vacuum oil-free units;7. The unique structural design achieves high vacuum and can pump condensable gases;8. The corrosion resistance can be achieved by changing part of the material.
