NEEDS & WANTS

Challenging low speed pattern around shaft seals in Twin Screw Pumps (TSP).

Molded elastomers are required due to Clean In Place (CIP) procedures, but also limits qualities available for use.

The EHEDG (European Hygienic Equipment Design Group) test procedure is used to verify CIP.

SOLUTION

Having the incentive to only use standard sized O-rings within the design, a working solution being able to successfully pass the EHEDG test protocol was designed.

CUSTOMER GAIN

The customer can now apply virtually any elastomer quality being requested by the end-users without being limited to what is available as molded parts.
