EDH Balanced Double Cartridge Mechanical Seal For Water Pump Mixers Agitators
Huhnseal Type EDH Balanced Double Cartridge Mechanical Seal for Pumps Mixers Agitators
Cartridge Mechanical Seal
EDH
Balanced double cartridge seal with hygienic design
The EDH series has been developed by Huhnseal for applications in the Hygienic sector, where the highest levels of process integrity, cleanability and operational reliability are required. The design follows a hygienic engineering approach in accordance with EHEDG principles, supporting CIP/SIP processes and reducing critical areas and contamination risks.
The EDH design concept is based on a double, balanced configuration that enables separation between process and atmosphere through the use of a barrier or buffer fluid. This solution increases system safety in the event of product leakage and provides more controlled operating conditions at the seal faces, making it particularly suitable for applications where the seal may be required to operate under dry running or highly transient conditions. The cartridge execution ensures safe handling, repeatable axial positioning and simplified installation, making the EDH suitable for integration on a wide range of rotating equipment used in highly hygienic processing environments with severe operating and cleaning requirements.
Features and Benefits
- Developed according to EHEDG hygienic design principles. Ensures high cleanability and reduced contamination risk.
- Double balanced configuration improves thermal stability and allows axial movements and tilting compensation.
- The flushing collar ensures a correct lubrication of the seal rings on the top of seal and eliminate the air pockets.
- Material selections are optimized for both product and barrier sides, using food-grade and hygienic material families.
- The patented Lip-O-Ring® on the product side supports stable operation and a hygienic sealing interface.
- Double seal arrangement allows the use of a barrier or buffer fluid to separate process and atmosphere and stabilize seal operation.
- Suitable for highly viscous, sticky or crystallizing products and for applications with frequent CIP/SIP cycles.
- For rotating equipment such as pumps, mixers, agitators and process machines exposed to intensive CIP/SIP cleaning.
