Rod seal - Import export

Design of the housing in the form of a groove should be avoided if possible. If this is not feasible, good housing and seal cleanability must be guaranteed. The hygienic design requirements can be met by having a particularly large groove base radius, avoiding notches and having a split housing. For WIP/WOP cleaning it is important to be able to remove and replace the seal without damaging it. Given a suitable machine design, cleaning in place is also possible.

The main applications are liquids at very high pressure. This seal can also be used for gases if the maximum operating parameters are restricted.

The MANOY® U‑Cup is a pressureactivated sealing system. This means that the total sealing force is only ever as high as required to seal the prevailing pressure. This friction optimization saves energy.The MANOY® U‑Cup seals gases and liquids and also highviscosity fluids and pastes in a nonstandard version

These sliding rings are the solution for designs which only allow room for a small or low housing, but require an operating pressure up to 80 Mpa. They are ideal for retrofitting into existing O‑ring grooves

The tandem configuration of type 116 allows static pressure maintenance in the critical unpressurized range and at low pressure. The security of this function is guaranteed by use of the IDG materials U95, U96 or U99 on the low pressure or atmospheric side.

Elastomeric wipers/scrapers are used in combination with the MANOY® sliding ring, the MANOY® U‑Cup or other rod seals.
