Replacement Union Slip x Thread for VarioS pump

[enb141]

Hi guys, I'm trying to find a replacement union for my varios pump, unfortunately I did glued bad with the PVC pipe so I need to buy two 1" fittings, I already bought one but it seems like the threading is not the same.

Have you searched for Varios spare parts?

Isn't it standard sizes? I have a home Depot union attached to the outlet of my varios s8

 

[enb141]

Are you or have you tried to plug directly to the pump or are you using something after the included union?

I'm looking for a union that fits the white threads of the pump as seen in the picture.

Those are metric threads. I bought a PVC threader for standard on Amazon and used the 1" on the pump. I then used a Home Depot threaded union. worked great

Do you have some pictures or links of the parts you got?

This is what I got. the threads from a 32mm(pump) is close enough to make this work. I also put the female end of the 1 inch union into boiling water to expand it slightly. NPT is a taper thread and heating will allow to set down further and seal.

Thanks, but I think I found the replacement parts in UK, is cheaper an easier.

That is BSP (British Pipe Thread) it is not going to work. US is NPT (National Pipe Thread) not the same thread pitch as BSP. That is also Solvent weld metric (slip) to BSP

Actually the threaded part I needed to be BSP, as far as I know the Varios uses them instead of NPT. then for the Solvent is 1", that's supposed to be NPT that's why it shows as metric and imperial.

I am having the same issue as you: Needing a replacement for the Varios 4 starting at the white threads. Can you elaborate more on your solution? Do you use the threaded female side of the union on the male pump threads?

McMaster-Carr, in the USA, has BSPT to Inch fitting Adapters.

Do you have the link, or do you know how to find it in their website?

Hope this helps. BTW, I believe most of the 24Vdc and 36Vdc Pumps with the Controller are BSPT, “British Standard Pipe Tread.” You will still need the Gasket, that came with the pump, for a water tight seal.

Thanks Steve! this is exactly what I needed

Looks like the you could use the adapter that steve provided to convert from metric threads to us standard, then it'll fit the standard schedule 40 pipe and fittings commonly available. So convert from metric to standard, then use any standard union you want
