XRN Process hydraulic diaphragm metering pumps XRN pumps benefit from thirty-years design experience gained in developing process hydraulic diaphragm pumps. Le pompe serie XRN sono realizzate sulla base della trentennale esperienza acquisita con lo sviluppo delle pompe a membrana idraulica di processo. Innovation lies in the combination of a hydraulic diaphragm process pump head with a reliable, economical, few-components design mechanism. L’innovazione consiste nell’aver abbinato un sistema idraulico di processo con un meccanismo affidabile, economico e con un numero ridotto di componenti. XRN...

Pompe dosatrice di processo a membrana idraulica Constructions characteristics • HYDRAULIC SYSTEM: In spite of reduced dimension hydraulic system is designed exactly like as the API 675 process pumps. It is the so-called .“smart diaphragm” .or mechanically actuated replenishing. The restored oil quantity is set by diaphragm position only, with self-controlled maximum deformation. .In the event of critical NPSHa or closed suction piping, “smart diaphragm” avoids .oil overfeeding that would result in overexpansion and rupture. Modelli base • Contour plate free technology. • CONNECTIONS: Threaded...
