Beginner Pump Question

[Marko S]

Hi all,

I have been reading the forums extensively about pumping and I have a couple of questions:

1. Lots of talk about "high proof" pumping and the requirements for it. Does "high proof" in this context mean 190 proof? or 160+? or does it also mean 80-90 proof?

2. I have a Sandpiper S05B2G pump: https://www.zoro.com/sandpiper-double-diaphragm-pump-conductive-acetal-air-operated-14-gpm-s05b2g2txns000/i/G5376183/

The pump body is Acetal, and the diaphragm is PTFE. If grounded, is this pump suitable for 190proof? How about 90 proof? The pump is ATEX rated, so does it even need to be grounded, or do I just need to make sure the vessels are grounded?

 

Thanks in advance for your answers.

Marko.

Acetal is rated excellent with ethanol.  You will absolutely need to ground the pump.

I have a couple little snapper pumps I use daily they are great little units for the money. Yes be sure to ground them

Great! thanks for the replies. Does that mean that, once grounded, I could use my pump to transfer anything from 80 proof to 190 proof?

 

Thanks again.

Yes.  We have one that we use to move neutral spirit to the tank to macerate our gin and one that we use to move the gin to the tank to proof down so yeah 190 down should be fine
