MPA1001 diaphragm vacuum pump

 The working principle of diaphragm miniature vacuum pump is: the circular motion of the motor, the reciprocating movement of the diaphragm inside the pump through the mechanical device, so as to compress and stretch the air in the pump chamber to form a vacuum, the pressure difference between the suction port and the external atmospheric pressure is generated, under the action of the pressure difference, the gas is sucked into the pump chamber and then discharged from the exhaust port.
