most important, what is the application ? and what is the problem ? What grade are you using ? depending on your location, there are probably several appropriate alternative products.
and put an overhead crane in the building.
Without a building, the pump will run until it doesn't and then if you can find it, it won't run again till spring. I know of one company in Edmonton who still can't find about 100 tons of steel in their yard (under the snow )
R and that should be taken ibto considerationemember the space they use up in the electrical room. Some installations require enlargement of the romm, additional ventilation / air conditioning etc,
thanks for the plug, unclesyd !!
namsco, wear plate performance is significantly affected by degree of impact versus abrasion, size and type of material, any chemical complications etc. If primarily abrasion, the chrome carbide overlay is worth looking at.

Try making the flights from chrome carbide overlay plate. If its dry, you could also try rubber ~or if wet , urethane.
For the hanger bearings, perhaps surround with a box, and blow a small amount of air into the box.
Where are you located ?
I endorse Ron's suggestion ~ 3 or 4 inches of castable refractory should protect the metal ~ remember to use plenty stainless steel ( or equivalent) anchors.
one of the items you have to remember is there is a time factor.. Frequently when there is a problem, you are not dealing with a steady state situation; the cause of the heat generation maybe somewhat localised, and not located in close proximity to the sensor, or if the oil temperature is...
it's been years, ok, decades since I was involved in cooler grates and their specs but from what I remember, if you need HH or HK grates, you ( or they) are not operating the cooler correctly
more details please ~ are the pumps operating on a commen header ? or in series ? My first impression is there could be some form of thrust, or reverse thrust, (unanticipated) occurring at the shut down. Did they work as designed when they were running ?
burnt2x,
Komatsu has 100s of similar diesel electric trucks in use here in the oil sands and coal mines. 930E, 830E etc with GE wheel motors. Some owners perceive better peformance and reliability compared with the mechanical trucks, and CAT is now building a 360 ton truck equivalent to their...
An alternative, if the configuration allows, would be to use a magnetic or fluid coupling in the drive. I put some on a stacker nearly 30 years ago, and it's still running !
