EHEDG Type EL Class I

Individual components that can be cleaned in the in-place state (CIP).

The European Hygienic Engineering & Design Group (EHEDG) is an expert community comprising machine and component manufacturers, specialists from the foodstuff industry as well as research institutes and health authorities. The organisation was founded in 1989 with the intention of strengthening the awareness for hygiene during the processing and packaging of foods. EHEDG conduct Type EL certifications, which are primarily intended for equipment used for CIP-cleaning. Class I is provided for individual components that can be cleaned in the in-place state (CIP). If these components do not meet all requirements in EHEDG Document 8 they have to be tested in accordance with the EHEDG in-place cleanability test. For this purpose the components have to be mounted into a pipe line. The entire SLH type range (SLH & SLH-4G) is certified in accordance with this type.

EHEDG Type EL Aseptic Class I

Components for use in aseptic applications

This certification procedure is designed for components used in aseptic applications. The three main criteria of cleanability, sterilisability and bacteria-tightness must be met to attain Type EL aseptic certification. The cleanability is verified by means of a Type EL Class I certificate along with additional tests for sterilisability and bacteria-tightness. The SLH-4G is certified in accordance with this type.

3-A Sanitary Standard

Doc. No. 02-11 Centrifugal and Positive Rotary Pumps

In the USA, the officially recognised Organisation 3-A plays a decisive role in the "Hygienic Design" sector. 3-A creates and publishes standards for hygienic design. They include specifications for materials and criteria for hygienic design. There are various standards for various areas. The SLH pump comes under Standard: "02-11 Centrifugal and Positive Rotary Pumps"
According to this standard, the SLH pumps are certified by ITT Bornemann.

Materials and articles intended to come into contact with foodstuffs

All materials used in the hygienic screw pumps are intended to come into contact with foodstuffs. Furthermore, the traceability of the parts is guaranteed. No certificate of compliance is required for this regulation. However, it will be granted on request.

VO No. 10 / 2011

Plastics intended to come into contact with foodstuffs

Elastomers do not come under this regulation and no additional synthetics are used in the hygienic screw pumps.

VO No. 2023 / 2006

Good Manufacturing Process for materials and articles intended to come into contact with foodstuffs

The GMP regulation does not demand any declaration of compliance in writing.
The GMP regulation applies for the groups of materials and articles (see above) listed in Appendix I of Regulation (EC) No. 1935/2004, for combinations of them and for corresponding recycled materials and articles. The GMP regulation promotes compliance with Good Manufacturing Practices, a quality assurance and control system and suitable documentation, which needs to be made available on request of the authorities.

Machinery Directive

CE Marking

The hygienic screw pumps are subject to the European Machine Directive and conformity is verified by a CE marking.


Zone 1 inside the pump

ITT Bornemann now offers innovative pumps that are also approved for pumping flammable mixtures, allowing full use of the design-specific advantages of the screw pumps to the fullest extent. The pumps correspond to Category 2 of Directive 94/9/EC and are ideal for pumping an occasionally occurring explosive mixture.
