Grease lubricated electric motor bearings are generally
pre-greased. Refer to the motor UI for information on
the motor lubrication schedule.

Pumps with grease lubricated thrust bearings and
electric motors are supplied with pre-greased bearings.

In the case of product lubricated

bearings the source of product supply should be
checked against the order; there may be requirements
for an external clean supply, particular supply pressure
or the commencement of lubrication supply before
pump start-up.

Approximate oil volumes are shown in section 5.2.2,
Bearing sizes and capacities.

Where the ambient is very low special lubricants are
required. If in doubt consult Flowserve for
recommendations of oil and grease types at these
lower temperatures

. Where oil lubrication is utilized

and the ambient is less than -5 °C (23 °F) ensure the
ambient is no lower than 15 °C (27 °F) over the oil
pour point or use the oil class SAE 5W-50 or API-SJ
and ensure the upper operating range of the oil is
then not exceeded. Where low ambient grease has
been specially fitted this is Shell Aeroshell 22.

5.2 Pump lubricants


5.2.1 Recommended rolling element bearing 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.
