Mid-range pumps

German pump and valve manufacturer, Richter Chemie- Technik, has launched a new range of PFA lined, mechanically sealed pumps specifically aimed at the mid-range of the process industries market.

Both the RSI (ISO/DIN code compliant) and RSA (ASME/ANSI code compliant) pumps incorporate PFA lining to provide high chemical resistance at temperatures from -30 to 150°C and full FDA conformity. These mechanically sealed process pumps can also handle liquids containing solids and have flow ranges from between 0.1-120m3/hr with delivery heads up to 100m.

The pumps are said to be cheaper than mechanical seal pumps made of corrosion resistant metals and to have a larger pressure and temperature range than full plastic or partially armoured pumps.
