Recoomended max pump speed

[vjc103]

Hi,

I am going to upgrade my single speed pump to a 100280 primarily because I want to skim bugs 24x7 and save some electricity. I have 2" plumbing.

I am planning to run at 1,200-1,500 rpm depending on how well it works for skimming/SWCG. Should I limit the max speed to 2400-2800 during priming to avoid possible cavitation ? Or there's no point in bothering ?

Thanks !

Can you tell us what a '100280' pump is?

Thank you.

oops...

I meant to write Intelliflo 011028. Not sure how I managed to type what I did

Sorry.

OK -- I have my Intelliflo limited to 2500 rpm during priming.

You should be fine anywhere up to 3000 that's where I limit VS on installs

I wonder if the default max speed is ever used by anyone ...

I use max speed 3400 for water features - sheers and a waterfall. 3000 when running the heater. 2000 all other times.

I have the Pentair 011018. I couldn't find a way to limit priming speed, only max speed. I needed to maintain higher speeds for the spa. I was able to disable priming. My pool seems to do well without the priming mode at start-up.

Just another option.

Very commom to use full speed when water features or a spa is on the pump. On my personal pool I have prime disabled too. I cant delay solar valve and if the pump comes on and its hot out the pump will run full blast on prime through the solar panels because the valve opens right away

I am hesitant to disable prime on mine since my regular run speed is 2000rpms. If power should blip and the pump loses prime, 2000 is not enough to prime it. Theoretically, it should not lose prime for just a power outage but you never know. I don't want the pump sitting there for hours running without water.

I installed the new pump (Intelliflo 011028) today. It was a bit tricky because the new pump inlet is about 1.7" higher than the "old" one and I did not want to re-plumb the manifold. Ended up with two 45 degree couplers to transition to the inlet height.

As recommended, I set the max speed to 2,500 and running a schedule at 1,500. Not sure if I should bother lowering to 1,200 as advised here.
