If the pump liquid temperature is below 80 °C, the following types of grease are recommended:
ESSO Beacon 2
BP Energrease LS EP 2
Shell Gadus S5 V100 2
Mobil Mobil lux grease EP 2
Castrol Spheerol AP 2 or AP 3
Texaco Multifak EP 2
Q8 Rembrandt EP 2 or Rubens
Statoil UniWay Li 62
If the pump liquid temperature is above 80 °C, high-temperature grease is recommended, e.g.
SKF LGHP2.
DESMI use SKF LGHP2 as standard.
Vibration levels higher than 7 mm/s at pump bearing are considered damaging and will normally
result in significantly shorter grease and/or bearing life
– especially for pumps not running. Hence
shorter re-greasing intervals might be required for pumps installed where external excited vibration
levels can be higher than 7 mm/s.
NOTE: Relubrication can cause a (usually temporary) bearing temperature rise of up to approx.
20°C - especially by mixing different types of grease and / or by overlubricating the bearing.
NOTE: Grease used for re-greasing must be compatible with the grease in the bearing unit!
