Self-priming chemical pump Malaysia is a positive displacement pump. It works by using a leaky diaphragm in its valve plate with the pump running counterclockwise, pressure builds up on the top side of the diaphragm and causesthe liquid to be drawn up through the intake from an external reservoir. Flow is not dependent on speed; therefore, it can be used at all operating speeds. When flow ceases by closing the valve, oil is returned to the suction side as well as into the tank.
