Flow limiter SP/SMB8
for mounting plates

Flow limiters are used in large oil circulation
lubrication systems. The task of a flow limiter
is to divide up the volumetric flow of the main
line into parallel individual volumetric flow
quantities and to “limit” these according to
requirements, or to keep them constant.
The volumetric flow generated is independent
of the system pressure and nearly independent of viscosity.
The SP/SMB8 flow limiter was developed
specially for mounting plates. The advantage of
this design is its simple and compact construction.
Using interchangeable plug-in nozzles, the
volumetric flow of the flow limiter can be set
stepwise from 0.08 to 8 l/min. This also makes
subsequent adjustments possible (necessary
when the unit is modified, e.g.). Tedious resetting and measuring are unnecessary.
The volumetric flow can be monitored simply
and safely with a signal transmitter or proximity switch (which is also subsequently attachable). A fault signal occurs when the volumetric flow drops to approx. 70% of the nominal
volumetric flow.

Advantages
• reliable
continuous dispensation of individual
volume flows
- self-adjusting metering, thus identical
volume flows despite different back
pressures
- wide viscosity range of temperature and
viscosity, due to stable system conditions
• easy system design
The demanded volume flow and flow
limiter nozzle and determined during
projection
• space-saving cultivation
in application of a base plate with an
access, up to 6 flow limiter attachable

See important product usage information on
the back cover.

• easy start-up
Pre-adjusted volume flows enable short
start up periods.
• effective monitoring of the volume flow
signal transmitter or piston detector reacts
to approximately 30% deviations of volume
flow
• wide range of operation, up to 200 bar
• optional ATEX vesion or integrated gear
indicator for volume flow
