Can this pump be used with a 5 gal reservoir if it's kept at 2800 rpm? Thank you
A: It should have no problem with that. The reservoir sizing rules-of-thumb state that a gallon of capacity for every gallon per minute pumped is adequate for most systems. As long as the pump isn't cavitating, the oil temperature stays under the material damage (seal) threshold, and the oil doesn't entrain excessive air during the normal use period for your application, that should be fine.

Can this pump be belt driven
A: No these pumps must be direct driven, no side load on the shaft.
