SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE
pure mist systems, ensure that the pure mist system is installed on the pump bearing housing, and is
operating in accordance with the manufacturer’s instructions. No further preparation is necessary.
3.3.1 LUBRICATION SPECIFICATIONS
The ideal bearing lubricant is mineral oil, preferably of the turbine type. It should not contain free
acid, chlorine sulfur or more than a trace of free alkali. It is suggested that the oil conform to the
following physical characteristics. See Figure 3-4 for recommended viscosity at specified pumping
and ambient temperature.

3.3.1.1 Synthetic Lubricants
If a synthetic lubricant (fire-resistant fluid) is to be used instead of the normal type oil for the
lubrication of bearings, gears etc., the material of all gaskets and O-rings in contact with the lubricant
must be compatible with the lubricant. Normal gasket materials will usually swell and deteriorate
when immersed in synthetic lubricants, and normal paints will peel from internal walls of reservoirs
and bearing chambers.
