Product Description

YH500 diaphragm is a kind of variable displacement type vacuum pump , vacuum pump is a kind of new, excellent function and high quality improved, on the basis of the advantages of learning, to eliminate disadvantages of similar products at home and abroad. The rotation speed of YH500 diaphragm vacuum pump is greater than 1390r/min; Input power is less than 500W; The limit vacuum is 700Kpa; Volume flow is 40L/min. The pump can be widely used for vacuum filtration, rotary evaporator, refrigeration, drying, vacuum concentration and molecular distillation.

Lanphan company is one of the diaphragm vacuum pump suppliers. Besides, there are many other kinds of vacuum pumps, such as small lab vacuum pump , tiny vacuum pump , small laboratory vacuum pump , and low volume vacuum pump . If you do not know how to select suitable vacuum pump, please contact us. We are pleased to give you professional suggestions and high quality products with reasonable price.

Working principle of YH500 diaphragm vacuum pump:

The motor shaft is covered with eccentric wheel, the end of connecting rod is set on the eccentric wheel, and the other end is connected to the soft film. As the motor spins and drives the connecting rod reciprocating. The rod is the driving diaphragm, which is fixed on the pump body to carry out the circular motion, resulting in the elastic deformation and the periodic change of pump chamber volume. In the pump, there is an inlet and a vent valve, and when the volume becomes large, inhale, and when the volume is changed to exhaust, thus achieve the purpose of pumping air.

Product features of YH500 diaphragm vacuum pump:

  1. There is filter material in the gas exchange position to ensure the cleanliness of the air;
  2. Work without medium, so no oil vapor pollution, is the ideal equipment to obtain clean vacuum;
  3. The new technology and new materials are used in the production process, easy to move and smooth operation, thus ensuring the ideal vacuum degree and higher air flow.
  4. Non - friction film motion, no heat, no friction loss. The diaphragm adopts imported rubber, corrosion resistance and long service life.
  5. Pressure adjustable design can meet a certain range of vacuum and gas flow;
  6. Bearing adopts imported classic bearing, running smoothly, low noise, high efficiency.
