The HD 13/18-4 S+, featuring a three-phase motor, is characterised by a pressure of 180 bar for a maximum flow rate of 1,300 l/h. With a high-performance water-cooled three-phase electric motor, an axial pump with all-brass water inlet and ceramic pistons. The electronic motor protection device ensures a longer life for the unit, as in the event of failure, overvoltage or undervoltage, the unit won’t shut down automatically. Life is further enhanced by a fine water filter, which protects the pump from impurities in the water. The EASY!Force pistol-grip reduces the recoil force to zero. It features a reliable EASY!Lock connection that is 5 times faster, as well as a ceramic valve for 5 times longer service life.
