Product Description

YH Diaphragm Vacuum Pump is a kind of variable volume type vacuum pump, and is a new type with excellent functions and high quality after improvement on the basis of learning merits and eliminating shortcoming of similar products at home and abroad. This pump can be widely used in experiments of vacuum filtration, rotary evaporator, refrigeration, dryness, vacuum concentration and molecular distillation.

Working principle of YH diaphragm vacuum pump:

The motor shaft is sheathed with an eccentric wheel, one end of the connecting rod is sheathed on the eccentric wheel, and the other end is connected with the soft membrane. With the rotation of the motor to drive the connecting rod for reciprocating motion. The rod is driven diaphragm which fixed on the pump body to do recycle motion, to generate elastic deformation, so that pumping chamber volume changed periodically. In the pump body, there are an inlet and an exhaust valve, inhale when the volume becomes large, exhaust when the volume becomes small, thereby reach the purpose of pumping gas.

Product Features of YH Diaphragm Vacuum Pump:

  1. There is filtering material in the gas exchange position, thereby ensuring the cleanness of air;

  2. Working without medium, so no oil vapor pollution, is the ideal equipment to obtain clean vacuum;

  3. New technology and new materials are used in the production process, it is easy to move and work smoothly, thus ensuring the ideal vacuum degree and the higher air flow rate;

  4. Using non friction of the film body movement, no heat, no friction loss. Diaphragm uses imported rubber, corrosion resistance, long service life;

  5. Pressure adjustable design, can meet a certain range of vacuum and gas flow rate;

  6. The bearings use imported classic bearings, smooth running, low noise, high efficiency.
