PFA lined gear pumps transfer aggressive liquids
A
Michael Smith Engineers product story
Edited by the Engineeringtalk editorial team
Jul 23, 2009
Liquiflo has developed a range of magnetically driven PFA lined gear pumps, which avoid the expense associated with pumps made from expensive alloys or exotic metals.
Available through Michael Smith Engineers, Liquiflo PFA lined stainless-steel pumps are suitable for difficult to handle liquids such as hydrochloric acid, ferric chloride, sulphuric acid, hydrofluoric acid, sodium hypochlorite, nitric acid and chromic acid.
They are also a good choice for high purity applications in which media contact with metallic components must be avoided.
Among the advantages of PFA lined stainless-steel housings for these types of pumps are that: they do not suffer from wicking problems associated with fibre-reinforced housings; and the effects of heat entrapment and corresponding thermal-expansion issues are minimised, as are the effects of fluid absorption.
The PFA lining also increases the strength and durability required for process pump applications.
In addition to their corrosive resistance, Liquiflo PFA lined pumps provide smooth, pulse-less flows, making them easy to monitor and control.
Their accurate output (within +/- two per cent) means wastage is eliminated.
Liquiflo PFA lined pumps are designed for easy servicing so downtime for routine maintenance is minimal.
They are ideal for challenging applications in water treatment, general chemical processing and in semi-conductor industries.
They are available in seven sizes in DIN and ANSI flanged connections and provide flows up to 47l/min at differential pressures up to 6.9 bar.
