J Line Pump
Horizontal Double Suction Centrifugal Pump – API 610 Process Pump
42 V1.032818
Basic oil-mist generating system should include the following:
1. An airline filter water separator to assure a clean air supply to oil-mist generator.
2. An air pressure regulator to control the oil mist generator atomizing air pressure.
3. An oil mist generator which includes a venturi nozzle, oil lift tube, reservoir and oil flow
adjustment screw.
4. Mist distribution manifold to convey the oil mist application fittings.
5. Spray application fitting to meter and convert the oil mist at each lubrication point.
Recommended Oil: ISO VG Non-Detergent Oil suitable for oil misting. (Refer to instructions
with Oil Mist Generator).
Air/Oil Ration should be 0.40 cubic inches/hour/cfm (231.5 cc/hr/m
3
/min).
Type of Oil Mist Fitting: Spray type.
Provide oil mist through the oil mist inlet as indicated on the General Arrangement.
Oil mist should be vented out thru the vent as indicated on the General Arrangement. (When pump is
idle and mist generator is on, a mist should be visible exiting the vents. When the pump is running, the
windage associated with the shaft, bearing, and coupling makes it difficult to see the mist).
Maintenance:
Periodically inspect the sediment bottle underneath the bearing housing. (Drain as required).
If bearing housing is dismantled, flush bearing housing with clean, lightweight oil (e.g. ATF).
Be certain that bearings have a light oil coating before startup.
6.3 PURGE OIL MIST – WET SUMP
When purge oil lubrication is supplied, the oil mist is used to maintain a positive
pressure in the bearing housing to keep contaminants from entering the bearing
housing.
The primary lubrication is by oil ring.
