Resin Beads Damaging Pumps

[doug atkinson]

Just a heads up  I’ve had a few pumps come in with very fine resin beads in the diaphragm. The source seems to be Unger but have not seen what beads are in their bags. It seems very fine mesh which is getting through the strainer.

Hmm interesting

The resin shouldn’t reach the pump

the pump should be before the resin.  To avoid such a problem

I've also read DI vessels doesn't even work with negative pressure?

What?

Disagree. Myself, and virtually every windie I know goes, R.O, d. i, into ibc, submersible pump into van mount, job done. Never had an issue

They do it different up here in Scotland Steve. Tap water in tank then through pump then through DI Vessel. You do get a lot of back pressure doing it that way.

Is back pressure an advantage or disadvantage  Doug?

I personally have a Di before my hose as a secondary just Incase my static Di depleted without me knowing.    That Di is AFTER the pump. 

My transfer pump is not submersible.   And even if it was, the impellers on them can handle debris between 1mm and 6mm.

di resin isn’t that big.

I find the back pressure an advantage for rinse down.

When you close the flow then open the water shoots out a lot further than if you had no DI Vessel in line. The pressure builds up in the vessel

Well you didn’t mention you had a static d.i in your previous post

You only get pressure build up if there is air in the DI vessel as water doesn't compress. Pressure occurs via hoses and air ingress.
