Centrifugal Pump Lubrication system
Centrifugal Pump Lubrication system
(OP)
Hello,
I'm preparing a datasheet for quoting centrifugal pumps, and I have questions about the lubrication system.
Could anyone please explain on what application these lubrication system would fit :
1. Ring Oil
2. Oil Mist
3. Flooded
4. Flinger
5. Pressure lubrication
6. Grease
Thank you,
Primaresa

here are some high level descriptions:
1. takes a bronze ring and "flings" oil around the shaft to lubricate bearings (this is the industry standard)
2. requires oil mist system ($$). best bearing lubrication/cooling.
3. bearing frame sump is filled (to a certain level) with oil. can be refilled without shutting down pump. requires maintenance crew to monitor sump levels
4. i believe it is the same as ring oil
5. Not necessary except for high energy density pumps (high HP, speed and thrust). Look through API and youll find the equation. but if your asking... you probably wont need a pressure lube system. and they are $$$$$$$$
6. There are actually two choices: 1) GFL (Greased for life) and 2) regreasable. GFL is greased for the calculated life of the bearing. With grease you will have to constantly send someone around and shut down the pumps periodically to grease the bearings.

High-level description would be enough for now
I will ask again if I have more question regarding pump lubing system.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Nonhazardous transfer pump
fluid : water
discharge head : 220 ft
NPSHA : 24 ft
single stage, single volute, overhung pump
Rated power : 30 kW/40 HP
From several vendors that have send quotation, the RPM of the motor usually around 2900 RPM.
For this pump service, do I need to quote for non-close couple pump?
At the moment still gathering inputs :)

in terms of lubrication - i would go with flood oil if you have a good maintenance crew; otherwise go with grease.
