The progressing cavity pumps from KNOLL Maschinenbau correspond now to the 3-A Sanitary Standard (United States of America). In addition to the EHEDG-certification the MX-Pumps now meet another very important standard of hygiene. This underlines once again the suitability of this pump for applications under the most stringent hygiene requirements.
The 3-A Sanitary Standard goes back to the 3-A Organization founded in 1920, which was a merger of three non-profit organizations. The goal was to establish criteria for the equipment and thus the product quality of dairies. This was intended to protect the health of consumers of dairy products. Since 2002, there is also the 3-A Sanitary Standard Inc. as a subsidiary organization of the 3-A, defining mandatory standards and monitoring any compliance with them. The work of the 3-A organization is widely recognized outside the USA and no longer just used in the production of milk, but, for example in the pharmaceutical field, too.
The certification due to 3-A primarily relies on the structural features, namely the structural design, surface quality and the materials used (for example the elastomers). Even the manufacturers of the seals must comply with this and prove certification of their products. This even extends to the level of staff members involved in the production: They must be certified for certain activities themselves.
This method of certification differs fundamentally from a certification due to EHEDG, where the pump is running a trial subjected to practically similar circumstances as appearing in normal production cycles.
A special feature of the MX-Pump from KNOLL is the fact that it has received certification to 3-A in its standard version, only with very minor modifications, covering the series MX20, MX30 and MX50. For buyers of such pumps this brings a significant price advantage, as in most cases no (expensive) supplementary parts are needed. Moreover, the supply of spare parts can be kept easier and faster because the required high quality already is included in the standard version of the series.
