Nivrah, that would depend completely on the application and bearing type and type of service.

As you can see from the video the process is rather straight forward; I believe the velocity requirement is to prevent the posssibility of loss of cut out pieces.

Critical speed. At certian RPM's some equipment, well all equipment has the tendency to flex and stretch causing it to vibrate. In a rotating equipment run up, if you are using VFD's or some other method of governing speed, one needs to push through known critical speeds quickly. Do not rest...
Ask him what type of vibration he seems to be worring about, transmitted or inherent. In other words is he worried about vibration from background machinery at the facility or from the fluid/vapor flows themselves. It seems awful general this request of his.

Short question, long answer. Depending on the design of the pump is what determines the placement of the thrust bearing and type. Is it a 'balanced' pump? Does it pump hot fluids or nominal temp fluids? What types of pressures is the pump designed to generate? Thermal growth plays a huge...
rmw, I agree completely, that falls under many strange things I have seen [pipe]

We use both methods here. Automated greasing devices come in many types and designs and can be used for very small amounts of grease, (1 gram) Up to very large systems. It really dependes on what you want to spend on them.

I have not seen a frame 3 in years and agree I do not think they are made...
