Hygienic Equipment Design Group) as fully CIP cleanable to their
protocol, and therefore is ideally suited for applications where
cleanability is paramount.
Also the OptiLobe pump range conforms to USA 3-A Sanitary
Standard and all media contacting components are FDA compliant.
The pump features the "EasyFit" front loading seal which allows quick
and easy inspection or replacement without the need for pipework
