The unit's compact dimensions ensure trouble-free transportation between sites.Its single cylinder four-stroke air-cooled engine is easily started with the pull starter. The pump's brass cylinder head and stainless-steel valves are designed for tough professional applications and ensure a long service life.The infinitely variable detergent metering ensures exactly the right concentration for the job and therefore helps reduce chemical consumption. A built-in safety valve reliably protects the unit against over-pressure.
