Pointing Limited, part of Universal Foods of Milwaukee, USA, relies upon air operated double diaphragm pumps from FPL in the production of speciality flavours, used in the food and pharmaceutical industries.
The Flotronic "One Nut" quick maintenance pump handles liquids that include botanical extracts, concentrated fruit juices, alcohols and a range of solvents. Three 1" stainless steel 710 Series pumps have been in use for over five years, requiring virtually no maintenance. They replaced progressing cavity pumps which suffered continual gland leakage and the risk of over pressurising their system.
Commented Barry Gorman – Engineering Manager: "We like the simplicity of the Flotronic pumps and, in particular, the inherent safety feature which means the discharge pressure can never exceed the air inlet pressure".
The pumps are used to transfer media from drums, tanks and IBC’s, and to feed plate filters for the removal of plant fibrous materials.
"I also like the flexibility of use", commented Barry, "as I can easily switch from one product to another as they cope very well with both thin products such as solvents, and thick products like concentrates. When it comes to maintenance, well you make them too good, they hardly ever need attention!".
