Suction filters are used as safety filters to protect pumps from gross contamination which can cause them to grip.
They are available in 2 styles:
- Suction Strainer (STR, MPA, MPM)
- SF2 external filters, for mounting semi-immersed under the oil level
SF2 semi-immersed filters, which shut off oil flow while the filter element is being replaced, replace the butterfly valves usually used for servicing hydraulic pumps.
