The possibility of using a high-pressure pneumatic pump in the porcelain industry is discussed. The results of the tests carried out by pump manufacturers to check the dependence of water supply on the pressure and counter pressure of compressed air are described. The pumps are actuated by an electric motor of power 7.5 kW and force impacts are implemented via a wedge-belt transmission, a worm reduction gear, a crank-shaft, a piston, a working fluid and a membrane.
