Food and Pharma - Downtime reduction - Dairy cooperative

Plant shut down at dairy factory

A big Dutch dairy cooperative had weekly problems with leaks during maintenance of its alkali and acid tanks. The staff had their work cut out replacing broken O-rings in the circulation system, in a very inaccessible place. When leaks occurred, the whole plant had to be shut down.

O-ring for food

For a solution to the leaks, the cooperative turned to ERIKS BV the Netherlands. In the past, when replacing O-rings there was a choice between two types: NBR and EPDM. These were used in a pump that is equipped with EPDM and Viton©. The O-rings were only suitable for certain parts of the system and also wore out very quickly. The two O-rings were hard to tell apart. All too often the wrong O-ring was used, and that could result in leaks within days.

O-ring for cleaning agents

The problem had two causes. The O-rings were not resistant to the various cleaning agents (including concentrated 60% nitric acid and a 1.5% CIP mix of nitric acid and caustic soda), but also the staff was not properly trained to tell the different O-rings apart.

Foodgrade O-ring

ERIKS found a solution that dealt with both problems simultaneously: a high and foodgrade Kalrez© O-ring, which is resistant to both media. So now there is only one O-ring in use that lasts at least a year and the customer saves on maintenance costs. That is ERIKS' added value!

Sustainable cost savings

‘The Kalrez© O-ring is made from the best, but most costly material available. But when you consider that it lasts at least a year, and that the plant doesn’t have to be shut down all the time because of leakage, the savings far outweigh the costs’.
