Pump Advice

[Ciderhead]

As stated above I sell Ryton and other PPS products for a living.

Ah crap!! So that listing is BS then??

Thanks for the heads up - at least I can cancel the order.

Cheers.

It's not going to kill you and doesn't have anything like lead in it.
Varying versions of Ryton are used for food contact just nothing that is injection moulded which the pumps are.
If you are concerned just flush the system with hot water before use, that will take out 90% of any migration of ingredients that come to the surface
This has raised up a whole series of issues because I thought chugger pumps were polysulphone not PPS.
I will be emailing them later and let you know how I get on.

Much appreciated ! Thanks for the advice on this...

Have a look at this........

Can't see if it's food safe.

Is that the same as the one in Belfast?
Not sure if it's even as good as this.......

and more expensive.

Cheers for the pointers.
One is...
"5 Pump material PA66+GF30% (optional)"

The other has no mention of the specifics of the materials used.

I did a search for the above and found this PDF that explains the various materials...
http://www.davis-plastics.co.uk/EngineeringProductInformation.pdf?oo=41627715

The section under "NYLON - Cast (Polyamide PA)" only references the mechanical properties but no food use suitability, whereas others in that list specifically mention suitability.

A big thanks to ciderhead for the advice regarding pump materials suitability.. Definitely learning a lot more than I ever thought about plastics and their use/suitability for food applications
