Water jet machines consist of three main parts. High-pressure pump, cutting head, abrasive dosing unit and high pressure systems. Suggesting that the nominal working pressure of 4000 bar high pressure pumps usually are manufactured. All pumps are produced in the world adorn the catalog values for these aspects give to each other. However, the pump 24 hours a day 365 days or so to run lightly artlardam , the first question which must be present when talking about the quality of the pump. Pumps genellikle15hp world markets, 30 hp, 50 hp, 60 hp, 75 hp, 100 hp, such as defined by the forces. However, according to the pressure is constant, the power is a function of pump flow. Pump flow rate increases, the number of the pump and breast feed the nozzle diameter increases. Nozzle diameter grows, the cutting speed increases. 1600*3200 2000*4000 2000*6000 2000*8000 1000*2000
