Plumbing on Vectra M2

[canadianeh]

I plan to use Vectra M2 on my new Reefer 250. The manual says the input fitting is 1.25” and output is 1”.

If I use 1” PVC for my plumbing system, does Vectra come with 1” adapter? Will it reduce the performance if I use 1” input fitting instead of the recommended 1.25” fitting?
I plan to use soft tubing and connect it to the hard PVC to eliminate any noise and vibration if there is any.

The blue collar on the M2 output is for 1" pvc. You won't need anything else.
On the suction side, I would not reduce it down. It's hard on the pumps.
And fwiw, I've plumbed 4 Vectras straight to pvc and there was no vibrations.

Ya this pump is insanely quiet and doesn’t vibrate. I don’t have any plumbing on the suction side.

You could save a little $ and go with a Vectra S2.

I know but I will run reactors and have 90 degree elbows. I rather to have a bit more.

So, it's going to be a external application?

Could you explain. Which models and did you use and did you still use the blue collars. I have been trying to figure out if the second gen Vectra pumps can be hard plumbed without the blue collars .... and the limited information appears to suggest the answer is no.

I have the L2, no vibrations and insane power, love! Hope it lasts...

My first 2 vectras were the M1 and L1 that I used pvc.
My third was a S1 which was plumbed using the blue collar for the outflow as well as the M2 I have now on that tank.
Both of the last 2 were internal.
I would suspect that since ETM does not sell the white pvc fitting adapters that they used to ( BST to NPT threads), that the threads that the blue collar uses are compatible to what we use.

Having said what I did, I took the suction side blue collar from my M2 out to my shop and looked through my boxes of fittings until I found a 1-1/4" male threaded fitting. The suction side is supposed to be 1-1/4", right?
So the fitting I found would screw into the blue collar, but only a couple turns.
And comparing the threads, it's obvious the blue collar threads are much larger that my regular pvc fitting threads.
So, you can't seem to get the pvc fittings they used to sell to accommodate the pump thread. What did ETM do with the second gen Vectras?
I think your only option was what was suggested in the previous thread about switching out the volute body.

Internal

 

[mfinn]

Internal

So there is no reason to worry about the suction side.

I am worried if I downsize the input pipe size it will effect the performance

I think we are talking on 2 different levels here.
In your first post you asked if dropping the suction side down to 1" from the stock 1-1/4". I said no it isn't a good idea.
So after a bit I was wondering if you were going to use the pump internally ( submerged in the sump) or externally, ( outside the sump, dry). Because if you had a sump that already had a 1" bulkhead drilled in it for a return pump already, the question would make sense.
But you said you were doing a internal return pump and that's when I said there is no reason to worry. Because there would be no reason to attach any kind of pipe to the suction side, if it's in the sump.

Oh yes yes. I got confused sorry. I plan to connect the main drain line to clarisea. Sorry for the confusion. Does the pump comes with input protector from stuff to get suck into it.

No, they don't have a inlet screen.

That's a sump brand?

Clarisea is a filter roller

Got it.
