9.4.2
Lubrication interval
The bearings may be re-greased with any lithium-based grease that conforms to the
specification detailed in Table 9.4.1-1.
The lubrication interval depends upon the shaft speed and the bearing operating
temperature, as shown in Table 9.4.2-1.

Table 9.4.2-1 Recommended lubrication interval for bearings @ 70
°
C (hours)
The pump should initially be re-greased after 250 running hours or the recommended
interval (whichever is less), unless stored for longer than 12 months before start-up, in
which case the long-term storage instructions should be followed (See section 1.2).
Multiply above lubrication intervals by the factors given below if the normal bearing
operating temperature (measured on the rim of the bearing end cover) differs from 70 °C.
Temperature (°C) 50 60 70 80 90 100 110 120
Multiplier 2.5 1.6 1.0 0.65 0.40 0.25 0.15 0.10
While the bearings and specified grease have a maximum operating temperature of
120°C, it is recommended that temperatures above 100 °C be avoided. However,
transient temperatures between 100 °C and 120 °C are acceptable immediately following
re-greasing.
