Product Description
the circular power from the motor is converted into oscillating movement by an
eccentric, which moves up and down its central point, this motion is then transferred
to a diaphragm by means of a connecting rod, an elastic diaphragm, which in
conjunction with an inlet and outlet valve creates a pumping action.
