Safely transferring aggressive liquids, such as inorganic acids, bases and salts, requires a pump with features including non-metallic wetted parts and characteristics such as zero leakage. To meet these challenges, Liquiflo has developed a range of magnetically driven PFA lined gear pumps, which avoid the need for expensive alloys or exotic metals.
Available fromh Michael smith Engineers, these pumps do not suffer from wicking problems associated with fibre reinforced housings; moreover, 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, pulseless flows so they are easy to monitor and control. They are available in seven sizes with both DIN and ANSI flanged connections and provide flows up to 47 litre/min at differential pressures up to 6.9bar.
