A variable speed pump can pay for itself within a year or two in terms of electric saving, so waiting for the current pump to konk out may not be necessary. That was my line of thinking before and my old pump just kept going and going and never quit, even after 15 years of service. Then finally there was a good winter deal on the new variable speed pump at a local store so I pulled the trigger. I think variable speed pumps have come down enough in price that makes it easier to justify now anyway.
Filtering should not be dependent on RPM. If anything, filtering at higher RPM will cause higher system pressure reading, more resistance going through the filter. I don't even know what uniform filtering means. How do you measure it?
A lower RPM pump, beside saving electricity, would also allow you to run longer for the same turn-over, therefore reducing water stagnation.
