The pneumatically hydraulic high-pressure pumps of the series PMA are laid out for the promotion of liquids with pressure up to 2.400 bar, at a pneumatics printing of 7 bar. These high-pressure pumps become everywhere there
begun, where compressed air is available as energy source and where a high and/or highest hydraulic printing is needed for test or for test purposes and/or for other applications. With compression tests the systems which can be examined are filled, aired out with a suitable liquid (oil, emulsion, pure water) under low pressure and brought afterwards by the Madan PMA of high-pressure systems on the desired pressure. All pumps of the Madan PMA series are supplied in rustproof execution (high-grade steel material 1,4401). Thus long life span and maintenance-free operation are ensured.
