Catalog excerpts

PUMP & FILTRATION SYSTEMS > refinex® refitherm®Cast steel gear pumps for refineries and petrochemical processes MAAG Refinery and industrial plant applications are challenging. High process pressures and high temperatures are commonplace in such environments. Precisely in these environments MAAG gear pumps develop their full potential. Thanks to the extensive range of components and materials of constructions to choose from, MAAG gear pumps can be configured to suit customers specific requirements and therefore, are far superior to standard pumps in terms of performance and reliability. Your benefits ■ Wide viscosity, temperature, and pressure range ■ High efficiencies (due to tolerances and small clearances being modified in line with applications) ■ Precise displacement volume ■ Self-priming ■ Reliability and longevity ■ Suitable for API 676
