8 Inspection & Maintenance
8.4.2 Flushed Standard and Flushed Hard Face Rotary Seals
The Flushed Rotary Seal is used for applications that require additional lubrication or aseptic sealing. It provides the same rotary
sealing action as the standard rotary seal, but with one additional feature -- it lubricates, cleans or sterilizes the non-product side
of the seal. Flexible hoses are provided for flushing media. Supply each seal with either potable water (lubrication) or steam
(aseptic sterilization) at approximately 15 PSIG (1 Bar). Do not exceed 1 Bar. The product pressure in the Contherm
™
must
always remain higher than the pressure of the seal flushing media so seal flush fluid will not enter the product zone.
The Flushed Hard Face Seal Assembly uses the Hard Face Seal Assembly in combination with a second seal. The secondary
seal face can be of the standard carbon or hard face material.
The inspection, maintenance, testing and replacement procedures for the Flushed Standard and Flushed Hard Face Seal
Assemblies are identical to those performed for the Standard Rotary and Hard Face Seals.
