oertzen e 320 is one the most durable and reliable high-pressure cleaners on the market. there is a suitable ratio between the water flow and working pressure of this german-made high-pressure washer. so it is able to meet all cleaning requirements. e 320 high-pressure washer has a three-cylinder inline plunger pump, 100% duty electric motor and sturdy tubular steel frame so it can operate under the rough industrial condition even in continuous operations. the working pressure and the water flow of e 320 can be increased up to 310 bar and 22 liter per minute respectively.
the machine's high-pressure pump is driven by a three phase and slow running electric motor which is directly flanged to the pump. so the motor/pump unit has a maintenance-free operation and there is a perfect alignment between these two components. the robust surrounding steel frame protects the motor/pump unit against the external impacts.
e 320 electric high-pressure washer is an easy to use machine which can be handled easily. the machine's chassis is a tandem axle one with four solid wheels and parking brake. in order to safe operation and maximum level of pump protection, e 320 can operate in by-pass modus (pressureless circulation of water in the pump. in addition, thermostatic relief valve protects the pump from overheating. when the flow pressure drops below 2 bar, a low water cut-out will stop the machine. when the operating pressure is exceeded by more than 10 %, a locked and sealed safety/control valve opens and returns the water which cannot be taken by the nozzle into the suction line of the pump. the machine is also equipped with a pre-filter unit to avoid contamination.
the high-pressure water inline plunger pump of e 320 high-pressure washer is equipped with splash oil lubricated forged crankshafts, wear-free ceramic plungers, forged brass cylinder heads, and stainless steel valves.
