[Polaris 280 Cleaner Using Variable Speed Pump]

I am planning on pool automation if this works. An easytouch with the SWG cell. 

I have been able to run the pump at upto 2700RPM without cavitation. It seems cavitation begins to occur at somwhere between 2850 and 3050 RPM.

Yes I would like to get rid of the booster that runs teh 280. A lot noisy compared to the intelliflo @ 2750 rpm.

 

So the question i have is: is my current setup not working because I am not able to sufficiently prime the pump?

I do not mind adding the Jandy enrgi and bypas, but I was hoping to do that, if I could prove that the current setup does indeed work.

Thanks PC. 

Sorry but I am confused. It seems in your July 8, 2009 post; you seem to mention your setup for a polaris 280. The reason I was using 3/4 plumbing is, that is what the dedicated return line for the 280 is plumbed out to be.

I would like to stick with existing setup if the Intelliflo VSt can support build up of pressure as required.

Hey Pool Clown,

                     Do you have pics of your setup pls?

I am trying to do the same. 

Here is the setup I tried today with not too stellar results.

" Trying to bypass the booster pump and run the 280 directly off the Intellflo 2 VST Variable Speed pump (VSP).
Here is the experimental setup and results. Thoughts and guidance appreciated.

The return from the intelliflo to filter was disconnected. (have a union there, so just disconnected it)
Hard Plumbed ( w 3/4" Sch 40 piping + a 1.5" union+ 1.5"-3/4 reducer ) the return of the VST direct to the dedicate return line for the 280.

Observation: 
1- When trying to prime @ 2400 RPM: the pump does not fully prime. The pump strainer pot is only filled about 3" from the bottom. however, 
2- The Polaris 280 is crawling in the pool at the same at a very low speed.
3- Putting the return back to filter, pump primes normally.

Questions:
1- is the 3/4 plumbing directly after the Intelliflo, not allowing the air to escape out and causing priming issues?
2- Would using a 3 way valve from the return work? 1would go to the polaris 280, the other would go to the FNS60. I would prime with the output of 3 way diverted to FNS and after being primed, would direct the flow to the 280. 
3- Has any one been successfully able to run the 280 off the VSP?
