CKD Pressure Equipment

Hydro-pneumatic group consisting of two pumps placed on a bench, regulated by a wall frequency variator, for the supply of constant pressure water. By regulating the motor speed, the equipment adjusts to the variations in the flow demand. In real time, the pressure reading is carried out in the installation, and the speed Variator regulates the equipment to adjust the flow supplied to the demanded needs, to the constant pressure required

Application Constant pressure water overlifting equipment for use in irrigation facilities, boiler feeding, washing systems, sports, hospital and hotel complexes, reverse osmosis, filtration and supply to housing and apartment groups.
