WLW series oil-free vertical vacuum pump application:
WLW series oil-free vertical vacuum pump is an updated product of W series reciprocating vacuum pump, which is the main equipment to obtain rough vacuum. Due to the full sealing device, the complete isolation between the crankcase and the cylinder is realized, and the self-lubricating material is used for the piston ring, so the advanced oil-free lubrication is realized. Because of no sewage discharge, WLW series oil-free vertical vacuum pump is especially suitable for vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration and vacuum impregnation in chemical, pharmaceutical and food industries. It is especially needed to be applied in clean high vacuum or environment where gas needs clean recovery. WLW series oil-free vertical vacuum pump overcomes the pollution caused by the need of lubricating oil. If it is used to remove flammable and explosive gas, or when the compressor is used, special order requirements should be put forward to our company.
WLW series oil-free vertical vacuum pump features:
1. The limit vacuum degree of oil-free vertical vacuum pump is high (4.5-15mmhg).
2. Oil free vertical vacuum pump: filling PTFE piston ring can ensure normal operation of cylinder without lubricating oil, and avoid accidents caused by oil pollution, waste and forgetting to add oil.
3. Oil free vertical vacuum pump can be used to pump corrosive media by changing the material of accessories. Wlwf series is made of stainless steel or fluorine or titanium lining material, which can resist all kinds of acid, alkali and organic solvent corrosion.
4. The oil-free vertical vacuum pump can save energy (33%), water (50%) and floor space (66%).
5. The average wear rate of cylinder, piston ring, crankshaft and crosshead of oil-free vertical vacuum pump is greatly reduced, and the service life is prolonged (4-10 times).
6. The noise of oil-free vertical vacuum pump is reduced because of eliminating the inferior vibration of shear wave.
7. Simple and beautiful appearance, convenient operation and maintenance.
8. The oil-free vertical vacuum pump and roots pump can form roots vertical oil-free reciprocating vacuum unit
Performance characteristics
1. Pump coaxial direct connection design saves space and is easy to install.
2. The mechanical seal is used as the standard configuration, which eliminates the leakage and is easy to maintain.
3. The operation is stable and the noise can be as low as 62 dB.
4. Uniform corrosion resistant design, bronze impeller improves pump corrosion resistance, stainless steel material is more suitable for more demanding applications.

The pump body contains proper amount of water as working fluid. When the impeller rotates clockwise in the diagram, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring which is approximately equal to the thickness of the pump cavity. The inner surface of the lower part of the water ring is exactly tangent to the hub of the impeller, and the upper inner surface of the water ring is just at the tip of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent space is formed between the hub and the water ring of the impeller, which is divided into several small cavities equal to the number of blades. If the lower zero of the impeller is taken as the starting point, the area of the small cavity increases from small to large when the impeller rotates 180 degrees, and is connected with the suction port on the end face. At this time, the gas is sucked in, and the small cavity is isolated from the suction port when the suction is finished. When the mouth is connected, the gas is discharged out of the pump.
