Dosing Piston

For SIP (Sterilization In Place), the MANOY® AS dosing piston is fed into the washing hole, which must be designed so that the piston has sufficient expansion capacity during SIP at +140°C to avoid damaging its functionality and shortening its life. After the cleaning process the MANOY® AS dosing piston may only be moved into the dosing hole when a temperature close to the operating temperature (operating temperature +20 °C), and not to exceed +80°C, has been reached. A feed cone into the dosing hole of 10° max. and rounded edges are essential.

The encapsulated O‑ring widens the potential applications of the O‑ring. The core of the ring is made of silicone (VMQ) or fluoroelastomer (FKM). The plastic FEP (tetrafluoroethylenehexafluoropropylene) is used for the seamless encapsulation. The particular product advantage lies in the combination of the elasticity of the O‑ring and the chemical resistance of the fluoroplastic.

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.
