Vectra for Vertical head/basement sump

[Frozn]

Hello, I'm currently in the planning/ purchasing phase for a new setup. This new setup will involve a basement sump and I've been thinking of using the Vectra L1 for a return. Accordingly I'll have roughly 11-12' total head pressure and granted this gives me good circulation. I'm wondering if anyone has used either the M1 or L1 in a 2 floor application and how it correlates with the charts produced by Ecotech.

I've found most people are using them for under tank sumps or similar scenarios with no more then 4-6' of head.

Froz,

I would recommend ensuring you a good idea of what your head pressure will be. From there, determine the amount of flow your system will need. At that point, you will be able to determine which Vectra is best for your system. Personally, I like to use this head pressure calculator: https://www.pondliner.com/blog/head-pressure-calculator/

I have read elsewhere that you can plumb these pumps in series to achieve greater flow at higher head. Can someone from Ecotech comment on this?

For example, if I am reading the pump curve for an L1 correctly, it will provide 750gph at 15' of head. What would the flow be from two L1's at this head, plumbed in series on the same return line?

I installed an L1 on my basement sump that feeds a 120 on the main level yesterday. Plenty of flow at level 10 (max 12 leds) and only pulling 115 watts. I had to touch it to make sure it was even on! The pumps are silent and very well balanced.

Any idea re: your head pressure? What size pipe are you running for the return?
