My GR510 is so effing big, I couldn't fit their oem coolant tank, so I
ordered a fiberglass one from Ronco (60 gal: 55 x 20 x 14), which fits MUCH
better than the haas monster.
Now it's pump time. The Fadal has a nice 1/2 hp Graymills centrifugal,
really blasts at over 30 psi, but I'm not going to need blasted (flood) type
levels, cuz the haas has programmable coolant, so you get pretty well-aimed
coolant for all tools -- nice option.
AND the nature of the haas is such that you don't want flood-type coolant
(open gantry mill), and most of the ops are lite, mostly drilling, tapping,
contouring of 1/8" and 1/4" alum. The Z is only 11", as gantries aren't
famous for Z.
My heaviest ops are going to be prepping the table with mebbe 1/2-13
So the Q is: what hp do I really need? If the 1/2 hp graymill is any
indication, proly 1/4 MAX.
And the next Q is: Would a HD/HF centrifugal sump-type pump do just as
well? Or even Little Giant centrifugals?
Here's some graymills jobbies:
These both give head of about 30 ft, sposedly.
The graymills is certainly better built, will last longer, and the $300 for
their 1/4 hp won't kill me, but if a $50 HF will do, mebbe I can use it as a
sump pump when I need it.... lol
Did I say "give head"???
That should have been "have heads", of course.....
