3.4 Functional description of gerotor
pump units
)
See Figure 3
SKF gerotor pump units of product series 143 are used in circu-
lating-oil and total-loss lubrication systems in a flow rate range of
0.85 to 50 l/min.
The standard permissible ambient temperature is between 0 and
+40°C. Higher ambient temperatures are possible, though they lead
to a reduction in motor performance and thus the delivery rate. In
this case, the maximum permissible temperature of the pumped
medium must be reduced.
The permissible temperature of the pumped medium is between 0
and +60°C.
The gerotor pumps include a gasket set made of FKM (FPM).
SKF gerotor pump units feed lubricating and hydraulic oils from a
reservoir and into the pipe system of a centralized lubrication sys-
tem. In doing so, they increase the energy of the pumped medium
(pressure increase) to overcome flow resistance in the pipelines
(pressure loss), the components (filters, valves, distributors), and the
bearings and friction points.
SKF gerotor pump units of different types and performance ratings
are used depending on the type and size of the centralized lubrica-
tion system and the lubricant (see pump code or “Technical data”
chapter).
