Hi,
Has anyone got some tips for fitting the Spring-held PTFE cup-seals?
We heat them, in hot water to 100degC and pray. Previously we have used hot oil at 120degC and in a big oven to 180degC, at 180degC they didn't shrink back.
Any feedback would be great.
Thanks

We have a pump drive that is currently a 6 pole motor, to increase pump capacity it has been suggested that we change to a 4 pole motor(1200 -> 1800 rpm).
Is it really that simple?
What increase in current (starting and full load) can we expect?
Will the motor be the same frame size?
Thanks...

Hi,
We have just discovered a crack in the windage shroud in a 40MW 4000rpm coupling (turbine-gear) As always the OEM has quoted some 20 weeks delivery. In a previous job, circa 2003 I bought a 'copy' coupling from a firm in the USA on a much shorter turn time but it carried a hefty price tag...
Hi,
There seems to be a lack of information available on ANSI flanges over 24" diameter.
Can anyone guid me to where I might find the key info: Overall dimension, number of bolts, size of bolts etc.
Thanks
