I would think if the pump capacity was somewhat greater than the two unit's needs combined then things would work fine.
The actual flow rate/volume isn't just a function of the pump rated capacity - it is also limited by the size of the plumbing
and all elbows and other restrictions, all of which must be considered as a system.
a higher capacity pump in a system limited by small hoses and long runs may be a waste of money
. It sounds like the consensus is it works which is the only important thing!
