When pumping applications involve aggressive liquids such as inorganic acids, bases and salts, or those that are regarded as high purity where contact with metallic components must be avoided, the Liquiflo Polygard Series pump are the ideal choice.
The extensive MZR range of low flow, miniature, positive displacement micro annular gear pumps provide precise, accurate and smooth, low pulse pumping and dispensing of a wide variety of liquids, including low and high viscosity fluids
The high performance range of MICROPUMP leak free, pulseless magnet drive pumps are now available with all-new compact and lightweight electromagnetic brushless DC motors which provide increased torque and power.
The Finish Thompson Ultrachem Series of ETFE lined centrifugal pumps has recently been extended with two new models which increase the maximum flow rates up to 160 m3 /hr and maximum differential heads to 67 metres.
There are certain liquids, which, due to their composition, their characteristics, or how they react to process conditions (and in some situations, a combination of all three) will present challenges to achieving efficient, trouble-free pumping.
For many additive applications, the primary function of the pumps is to ensure that they generate sufficient differential pressure for the additive to be injected efficiently and smoothly into the main process line
