Flow limiter SP/SMB10
Dual flow series

Advantages
• reliable
- Parallel distribution of individual flow
quantities
- self-regulating metering with pressure
balancing valve, thus constant volumetric
flows even for different back pressures.
- wide viscosity spectrum, nearly independent of viscosity and temperature and
thus stable system conditions
- possibility of a reduced starting flow
• easy system planning
The required volumetric flow (the required
flow limiter nozzle) has to be determined
already during the project planning phase.

• simple start-up
Preset volumetric flows allow short
start-up times.
• effective volumetric flow control by
means of gear wheel-type flow indicator
with Hall-Sensor
• broad range of applications
• optional ATEX version

Flow limiters are used in circulating-oil
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 produced does not
depend on the system pressure and is nearly
independent of viscosity. It is also possible to
switch from the rated volumetric flow of the
SP/SMB10 to a reduced starting flow (1:4) to
prevent cold bearings from overflowing.
The SP/SMB 10 flow limiter was developed
specially for baseplates. 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 0.21 to 8.15 l/min. That
makes it possible to adjust the volumetric flow
rates at a later date. The SP/SMB10 series
comes with a visual/electric gear wheel-type
flow indicator that has a proportional factor
of 12 ml per revolution.
