Micro Liquid pump for Sale

The micro liquid pump refers to a micro air or water pump that can generate negative pressure, so it has one suction port and one exhaust port, it could supply continuously form a vacuum or negative pressure at the inlet and appear one slight positive pressure at the exhaust port ; The working medium is mainly gas.

The circular motion of the motor makes the diaphragm inside the pump reciprocate through the mechanical device to compress and stretch the air in the pump cavity to form a negative pressure, and a pressure difference between the suction port and the outside atmospheric pressure is generated. Under the action of the pressure difference, Inhale the gas into the pump cavity and exhaust it from the outlet.

The main medium of the micro-vacuum liquid pump is gas, which can work continuously for 24 hours and has several thousand hours of working life (intermittent use is far more than that); there is no need oil and lubricating oil which will not pollute the working medium, and allow the medium Rich in water vapor, no maintenance required; installation in any direction allows a wide range of medium temperature.
