APPENDIX
PURE OIL MIST LUBRICATION
FOR HPX TYPE PUMPS
OIL MIST INSTALLATION
Pump bearing housing is arranged for pure oil mist lubrication. The following connections are
provided in the bearing housing
- A 1/4” NPT with adapter oil mist inlet connection in the top half of the bearing housing,
between line and thrust bearings.
- A 1/4” NPT vent connection in the space between the rolling element bearing and the
inboard/outboard bearing housing cover.
- A 1/2” NPT drain connection in the bottom half of the bearing housing.
Remove inlet and outlet pipe plugs from above connections. Install appropriate reclassifier in the
top opening, leave open vent connections, connect oil recovery trap to bottom opening or leave it
open to act as relief.
OIL SUPPLY
The lubricating oil should be rust and oxidation inhibited and stray mist suppressed, manufactured
in accordance with good commercial practice.
The viscosity should be ISO VG 100 (approx. 470 SUS at 100°F).
The following oils are recommended:
ESSO ENMIST
CHEVRON VISTAC
SHELL OMALA
TEXACO TEXAMIST
