Ex aluminium double diaphragm pneumatic pump Lutz

Operation:
- The pneumatic valve is supplied with compressed air; this air is then led through the piston of the pneumatic valve (either in the upper or lower position) to the middle block where it is distributed between the two direction ports to emerge on the left or right side of the pump.
As soon as the air is in the air chamber, the air pressure acts on the back of a diaphragm, so that the product is pushed out of the liquid chamber into the outlet tube.
