Enclosing a vacuum pump to cope with washdown environments

28 May 2018

Gardner Denver has supplied a food packaging machine manufacturer, Proseal, with a solution to help ensure meets required hygiene and safety standards. 

Best hygiene practice in the food industry require machinery to be washed down at the end of every shift. This can pose a problem for vacuum pumps as the harsh working environments and corrosive cleaning agents used in the washdown process can result in rusting and reduced pump performance over time.

To overcome this challenge, Gardner Denver has developed a specially designed enclosure for its Elmo Rietschle VC 303 vacuum pump, which means it can be sited alongside Proseal’s vacuum/gas packing machines in wet environments.

The cover has been developed in line with the Hazard Analysis and Critical Control Point (HACCP) principles, which establish the appropriate food safety management procedures that businesses should have in place. Made from stainless steel, the cover means the vacuum pump can withstand wet environments without affecting its performance.

Commenting on the solution, Steve Windsor, senior development engineer at Proseal, said: “If a vacuum pump cannot be sited alongside the food packaging technology, then it has to be installed remotely and piped to the machine. This is a costly process, so it is in our customers’ best interest to have the pump positioned as near as possible to the food packaging system.??“Gardner Denver has created a stainless steel cover for its Elmo Rietschle VC 303 pump that is ideally suited to meet the needs of the wet environments in which our technologies operate. These enclosed pumps offer a very attractive ‘plug and play’ solution for us.”
