S series
AIR DRIVEN LIQUID PUMP
pressures in excess of 1,200 bar
This series of liquid pumps are single acting, single 125mm air drive units that are capable of pressures in excess of 17,400 PSI / 1,200 bar.
The Hidrokraft Pump model number reflects the pumps nominal pressure ratio , while the technical data indicates exact ratios.
The outlet stall pressure is easy to set by adjusting the air drive pressure and by simply multiplying the pressure ratio by the air drive pressure, the nominal liquid pressure can be calculated.
Suitable for water and oil.
