EGGER Reactor Pump for MMA Production

PMMA and MMA (Acrylglas)

Reactor Pump HT | HPT

The performant reactor pump developed for high temperature and high pressure applications in the chemical and petrochemical industries. Since many years a reference to handle multiphase liquids such as chemical mixtures with high gas content. Egger HT/HPT pumps are specially designed for loop reactor continuous circulations with catalyst and high gas contents.

CASE STUDIES

SM Nutritional Products AG at Sisseln in Switzerland

Sample of an EO reactor pump with high system pressures. 140 °C hot 3-phases-mixtures consisting on a liquid with catalyst and reaction gazes are pumped through a loop reactor. Centerline mounted pump and base plate with spring feet. In the wastewater treatment plant the chemical waste water is treated by horizontal mounted EO process pumps.
