ESH Centrifugal Pump Seals ISO9001 Hygienic Sector Shaft Seal Pump
Huhnseal Type ESH Single Balanced Cartridge Mechanical Seal for Hygienic Sector
Cartridge Mechanical Seal
ESH
Single balanced cartridge mechanical seal with hygienic design
The ESH series has been developed by Huhnseal for applications in the Hygienic sector, where operational reliability, cleanability and long-term stability are essential requirements. The design follows a hygienic engineering approach, with geometries supporting CIP/SIP processes and reducing critical areas and product build-up, in line with EHEDG principles.
The ESH design concept combines a balanced construction, application-oriented material selection and original technical solutions developed by Huhnseal to ensure stable operation under variable process conditions, frequent cleaning cycles and significant axial movements or angular misalignment.
The cartridge execution simplifies installation and ensures repeatable axial positioning, making the ESH suitable for integration on a wide range of rotating equipment used in the processing of sensitive and high-viscosity food products.
Features and Benefits
- Smooth and cleanable surfaces support effective CIP/SIP cleaning. Designed for hygienic (Sanitary) and Food & Beverage applications.
- Balanced seal design ensures controlled face loading and high stability. Allows particularly large axial movements and tilting compensation.
- Knife Edge seal face geometry reduces product adhesion and build-up. Ideal for sticky and highly viscous Food & Beverage media.
- Suitable for a wide range of rotating equipment in hygienic (Sanitary) and Food & Beverage processing, including pumps, mixers, agitators
- The patented Lip-O-Ring® on the product side supports stable operation and a hygienic sealing concept.
- Available with food-grade material combinations suitable for hygienic (Sanitary) and Food & Beverage processes.
- Optimized geometry minimizes dead spaces and product build-up, in line with EHEDG hygienic design principles.
- Cartridge design enables easy installation, safe handling and repeatable axial positioning.
