Adjustable cleaning performance

The unloader safety valve allows pressure and water quantity to be regulated continuously, giving the operator control over the cleaning output. The specified operating range is 30–170 bar, with a maximum pressure of 190 bar and water delivery of 300–1,300 litres per hour.

The 900 mm spray lance with rotary nozzle is part of the Premium configuration. The machine is also specified with a 25° stainless-steel jet nozzle.

Pump and operating controls

The KD1240-Premium uses a triplex-piston pump with a nickel-plated brass pump head, high-performance ceramic pistons and stainless-steel valves. Start-stop control includes a switch-off delay and total switch-off after 20 minutes, helping limit unnecessary running when the cleaner is not being used.

Premium equipment and mobility

The Premium specification includes a hose reel and chemical supply into the high-pressure jet, controlled by a metering valve. A 20 m DN08 high-pressure hose is specified, along with a 15-litre water-storage tank and chassis storage for accessories.

An ergonomic drawbar supports movement around the work area. The cleaner requires a 400 V three-phase electrical supply and is specified with 3 × 16 A slow electrical protection.

Operating considerations

The maximum inlet-water temperature is 45°C. The machine is specified at 97 kg net, so customers should account for its weight when planning handling and positioning. Follow the operating instructions for proper and safe use.
