Hint!
GEA Tuchenhagen recommends Rivolta F.L.G. MD-2 and PARALIQ
GTE 703. 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 from GEA Tuchenhagen under mat. no. 413-064, and
Rivolta F.L.G. MD-2 can be ordered under mat. no. 413-071. 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!
