3.4 Treatment of Trapped Oil
The TM201/401 is designed to discharge the trapped oil to outside through
the oil return port. Recover the discharged oil in a container and return it to
the pump when the pump is operated under no load or at stop.
However, do not return the oil to the pump if the oiliness of the recovered
oil is lower than the new oil used in the pump or if the oil contains water, dust
or the like or if chemicals like acid is used.
It can be a cause of trouble of the pump.
CAUTIONS:
①
If you do not dispose of the trapped oil, oil will stay between the
fitter element and the oil mist trap and oil mist will come out.
②
It is recommended to replace a filter element once immersed in oil
because clogging tends to occur.
③
Do not connect the oil return port and the pressure monitor mounting
port by means of a vinyl hose or the like. Oil mist will not be trapped.
