The Soavi Multi-Block VHP concept, developed for high-pressure applications, consists of a split block construction which minimizes fatigue stress due to peak pulsating pressures. The small parts used, engineered according to accurate FEM modelling, ensure precise machining and surface control for extended reliability. Special high-pressure gasket configuration, the use of special wear resistant materials and an extremely flexible plunger packing sealing system provide the ultimate, reliable and most effective solution for Very High Pressure operation.
