Hint!
GEA Tuchenhagen recommends Rivolta F.L.G. MD-2, PARALIQ GTE
703 and grease BARRIERTA L 55/3*. These lubricants are approved for
foodstuff and are resistant to beer froth. They have the NSF-H1 (USDA
H1) registration. They do not affect the taste or the consistency of the
products and are compatible with the seals in contact with product.
PARALIQ GTE 703 can be ordered under the material no. 413-064,
Rivolta F.L.G. MD-2 under the material no. 413-071 and grease
BARRIERTA L 55/3* under the material no. 413-137 from GEA
Tuchenhagen. Using other types of grease can result in malfunctions
or in premature seal failure. The warranty will also become null and
void.
A Manufacturer's Declaration for these products can be obtained from
GEA Tuchenhagen if required.
A thin film of grease is required on the seals to ensure the proper
function of the fittings. It reduces friction and extends the service life
of the seals. This is absolutely harmless from a health and hygienic
point of view.
Running dry must be avoided!
*Grease BARRIERTA L 55/3 only for seals VMQ
