* 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).

Most oils recommended for wet sump bearing

housings contain foam inhibitors as well as

antioxidants and anticorrosion additives normally

unsuitable for oil misting. Compounded oils CANNOT

be used for oil mist and anti-foam additives are to be

avoided. The above LSC grades are recommended

by Flowserve where Oil mist.

Where the pump is lubricated by oil mist

the amount of oil mist supplied (m³/h) is normally

calculated to be at least the bearing bore diameter

(mm) x the number of bearing rows / 25. The oil mist

should consist of at least 0.025 - 0.04 % oil content.

Where oil mist is utilized to lubricate bearings the

pressure in the bearing housing must not exceed

0.01 barg (0.15 psi).
