Principle: HLVP8 series of miniature diaphragm pumps are simply designed according to the principle of positive displacement pumps. By controlling the inlet and outlet of the diaphragm, a power drive is formed and the transmission mechanism pushes the piston to reciprocate, and the intake pressure pushes the diaphragm back and forth to do work to suck and discharge gas.
