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.

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’s pour point is at least 15 °C (27 °F)

below the ambient temperature 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.

* 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 greater viscosity index than the minimum acceptable of 95 (eg Mobil DTE13M) which

may extend the minimum temperature capability of the oil. Always check the grade capability where the ambient is less than -5 ºC (23 ºF).

†

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.

Normal compounded oils CANNOT be used with oil mist as anti-foam additives need to be avoided. Most oils recommended for wet splash

lubrication contain foam inhibitors as well as antioxidants and anticorrosion additives, so they are unsuitable for oil mist. Some synthetic

lubricants may attack the Nitrile seals used in a regular bearing housing. The LSC LSO oils are recommended for oil mist applications.

grades.

** Standard pre-packed grease for fitted antifriction bearings.

5.2.2.1 Food grade grease, when applicable:

NSF H1 Klubersynth UH1 64-62 is the food grade

grease option and it is NLGI grade 2.
