Les guides techniques EHEDG en Anglais

The objective of this guideline is to provide a set of minimum requirements for pumps, homogenisers and dampening devices for hygienic and aseptic applications, to ensure that food products are processed hygienically and safely.
Special demand is made on pumps, homogenisers and dampening devices used in the food processing and pharmaceutical industry with regard to CIP-capability, gentle product handling and ease of maintenance. In addition to this, pumps, homogenisers and dampening devices require good mechanical, hydraulic and thermal efficiency, a technically perfect construction and low-cost manufacture.

These requirements, their implementation and thereto related design principles are handled in detail in this guideline. The guideline applies to all pumps intended for use in food processing, including centrifugal pumps, piston pumps, lobe rotor pumps, peristaltic pumps, diaphragm pumps, water ring pumps, progressive cavity pumps, screw pumps, gear pumps and also to homogenisers, dampening devices and shall include any valves integral with the pump head and the complete homogeniser head.

Differences between the EHEDG Guidelines (Europe) and the 3A standards (USA) are indicated, where appropriate.
