RKM return line & suction boost
filters
RKM 100 RKM 201, 251 RKM 300 RKM 400, 800 |
RKM return line & suction boostfilters for the mobile industry areused in units with both open-loophydraulic circuits (e.g. operatinghydraulics) and closed-loophydrostatic drives (e.g.transmissions).
RKM filters therefore combine the
function of the return line filter of
the open-loop circuit and the
suction boost filter of the closed-
loop drive in one filter. The returnflow must always be greater thanthe flow rate of the hydrostaticfeed pump on these applications.Function
The return line flow of the
operating hydraulics is fed to the
filter via port A and is cleaned by
the filter element (full flow return
line filtration). A pressure
(standard = 0.5 bar) is applied by
the back-pressure valve V
This ensures that the filtered
return line flow is available to the
hydrostatic feed pump via port B
(full flow suction boost filtration).
Excess quantities are drained via
the back-pressure valve to the
tank (port T) |
