If the contact with the ethanol is permanent the Seeflex 040E is not suitable. If it is sporadic and low temperature then you should have no problem. You may need to run a few tests on the media to check the suitability, as it will depend on time and temperature of contact with the solvent and the application. Please contact one of our representatives to discuss this further.
Seeflex 040E is very strong and has been used with sugar, crystallized lactose, aggregates etc. Installing with an internal flow correction system is an additional way to further improve the system and avoid undue abrasion.
Between 3 and 9 pH is generally acceptable, and outside this it is largely dependent on concentration, application and duration of contact. It’s important to remember that the pH scale alone doesn’t specifically help determining resistance of the materials – the pH scale will provide an indication of the strength, but product type, concentrations and temperatures are far more important. Our woven Teflex is an excellent alternative for use with acids or alkalis. This is a pure PTFE media which can be used on most products and up to very high temperatures. It is best to double check with us if there are any concerns regarding media compatibility.
The resistance of the connector materials to chemicals is very dependent on the strength (concentration) of the chemical, the process and how the system is maintained (cleaned). The LM4 is a 100% Polyester woven fabric so its capability with either chemical is limited. Seeflex 040E is also limited with these chemicals – it is important to know the concentrations and the application. Teflex is the optimum material for use with chemicals as it is resistant to acids.
It depends on the type of oil. Some oils are very aggressive and would degrade the polyurethane and the tight seal of the spigot connections can also be adversely affected by oils.
Yes, sodium sulphate has a pH of 7 and will be suitable for Seeflex 040E.
This will depend somewhat on what is in the laundry soap. In general the Seeflex 040E will work well. There is often Sodium Carbonate or Sodium salt which may start to break down the Seelfex over an extended period. Unilever in New Zealand run the BFM® fitting on soap product without issue.
Yes – LM4 is fine with caustic soda in concentrations of up to 5%.
