Configuration/Illustration
The machines of the Mobile series consist of a low speed, oil-greased high
pressure inline plunger pump, driven by a low-emission 4-stroke motor in Vdesign. An oil-greased reduction gear flanged between pump and motor
reduces the high pressure pump speed. In order to extend the motor lifetime,
an oil shortage cut-out is installed, which stops the motor in case the oil level
drops below specified limits.
The feed water is directed with required admission pressure via a filter to the
high pressure pump which, together with the diameter of the spray nozzle,
boosts it to required working pressure. In order to protect the pump against
damage due to cavitation, a low water cut-out is installed.
A workshop-set and sealed unloader valve opens in case the operating
pressure is exceeded by more than 10 % and directs the water which cannot
be taken by the nozzle, back into the suction line of the high pressure pump. In
parallel it allows to continuously adjust working pressure and water flow.
By opening the rotary handle of the double lance the working pressure can be
adapted to the requirements at the cleaning object.
The machine is equipped with a safety shut-down system in order to protect
the high pressure pump against overheating. After closing the spray pistol, the
unloader valve returns circulating water back into the suction line of the high
pressure pump. In case the temperature of the circulating water exceeds
60 °C, a thermo valve opens, releases hot water which is substituted by the
same amount of cold water. When activating the spray pistol again, the
working pressure is re-generated immediately.
The range of applications can be extended by a variety of accessories
available from OERTZEN. Contact your local distributor.
