Where an adjustable body Denco oiler is fitted this should
be set to the height shown in the following diagram.
The oil filled bottle should then be refitted so as to
return it to the upright position.
Filling should be repeated until oil remains visible within
the bottle
. Approximate oil volumes are shown in
section 5.2.2, Bearing sizes and capacities.
Grease lubricated pumps and electric motors are
supplied pre-greased.
Where the ambient temperature is very low, special
lubricants are required. Where oil lubrication is utilized
and the ambient is less than -5 °C (23 °F) ensure the oil
pour point is at least 15 °C (27 °F) lower than the
ambient, or use oil class SAE 5W-50 or API-SJ and
ensure the upper operating range of the oil is then not
exceeded. IS0 VG 46 oil is generally selected for an
initial lubrication schedule.
Other drivers and gearboxes, if appropriate, should be
lubricated in accordance with their manuals.
5.2 Pump lubricants
5.2.1
Recommended oil lubricants
* Note that it normally takes 2 hours for bearing temperature to stabilize and the final temperature will depend on the ambient, r/min, pumpage
temperature and pump size. Also some oils have a very low pour point and good viscosity index which extend the minimum temperature capability
of the oil. Always check the grade capability where the ambient is less than -5 ºC (23 ºF).
** If preheated pure oil mist lubrication, LCS LSO 68 or LSO 100 synthetic oils are permitted.
†
Use LSC for oil mist. Oil parameters provide flash point >166 ºC (331 ºF), density >0.87@15 ºC (59 ºF), pour point of -10 ºC (14 ºF) or lower.
*** ExxonMobil SHC 524 synthetic oil has a pour point temperature of -54 ºC. This oil can be used for ambient temperature as low as -50 ºC.
