8.3.5 Clean the intake port dirt-trap and anti-suck back valve
A wire-mesh scr
een is located in the intake port of the pump to act as a dirt
trap for foreign objects. It must be kept clean to avoid a reduction of the
pumping speed. An anti-suck back valve is located inside the intake port to
stop the oil from returning to the intake pipeline. It must be kept clean to
prevent function failure leading the oil to return the intake pipeline.
For this purpose, remove the dirt trap and anti-suck back valve from the
intake port and rinse them in a suitable vessel with solvent. Then thoroughly
dry them with compressed air.
If the dirt trap is defective, replace it with a new one.
Note:
The cleaning intervals depend on the application. If the pump is exposed to
large amounts of abrasive materials, a dust lter must be tted into the
intake line.
