How can I connect a Pentair Super flo pump to a Aqua Rite SWG without using a time clock?
How do you connect a Pentair superflow VS Pump to a Aqua Rite SWG without using a time clock?

If you are trying to make sure that the SWG doesn't run when the pump is off, I got this idea from @laprjns
I use a CR Magnetic current sensing relay, part number CR4395-EH-120-110-X-CD-ELR . Here's how I wired mine.
If the pump is not running, it will turn off the SWG. Not sure from your question if this is what you are looking for...

Correct me if I’m wrong, but the unit you have listed there is the “EH” model, which means Energized High. This means that it will only trip if the amperage is ABOVE the set point. Don’t we want it so it trips when there is low amperage?

EH is the correct model. The output to the SWCG is wired to the "normally open" contact. This results in no power to the SWCG as long as the current to the motor is below the trip point. Once the motor current exceeds the trip point, power is applied to the SWCG.

@laprjns created the solution, I just copied it. He gets all the credit.

Gotcha! I was interpreting the “trip point” as when it opens the circuit, not closes it. Thanks for the clarification.
I’m also working on getting this set to function with 220v. I think it’s going to take a second relay, in order to have both 220v lines be interrupted.

Why can't your SWG be run on 120V?
Having two relays control 220V lines presents a safety hazard.

I’m open to suggestions. I’m far from an electrician, so I will be getting an electrician to do the work. I just want to get him the right parts.
I was just thinking using a Double Pole Single Throw (DPST) relay, in addition to the current sensing relay, would allow both poles of the 220v to be de-energized when amperage is below threshold. Reading around here, I see a few people have done the same.

Yes you can use a current sense switch to control a double pole relay for both sides of 220 mains. But this is another thing to fail. And it takes extra space in the control box.
So rewiring the swg for 120 vac is worth considering. It's usually just swapping jumpers. The current sense relay looks like it will handle a 1 hp motor. That's roughly 6 amps inductive. My swg's transformer draws 2.5 when set up for 120v.

All great info. If I ended up wiring the SWG to 120v, that would require a transformer near the equiment pad I guess? I don't have any 120v service running to the equipment pad; it's all 220v as far as I know.

In the US, it's rare for domestic 240vac wiring to be anything but two 120vac circuits having a 180 degrees phase difference, including a neutral. In that case, wherever you have 240, you also have 120. Sorry I have no experience with Canada. I didn't catch that originally in your profile. I'd go for the extra relay rather than a 240 to 120 step down transformer for sure.

I'm pretty sure our electrical standards are pretty much identical to yours in the USA. I'm going to provide the hardware to the electrician, and let him decide the best way to implement it. It won't be till next year when I install the SWG, so I have lots of time to figure out the details. I'm sure a the end of the day I will have a decent safety net by having the SWG flow sensor, along with this current sensing relay, to protect my SWG from turning into a bomb. This is all probably overkill anyways, since I generally run my pump 24/7
