XRN Series


The first compact hydraulic diaphragm pump with integrated safety valve. This solution combines the simplicity and cost-effectiveness of the spring return with the advantages of the hydraulic diaphragm, using an innovative mechanically actuated oil replenishing system, representing the ideal solution also for process applications. The very small dimensions and the integration of a safety valve contribute to reducing the costs of construction and operation of the installation and to increase its intrinsic safety.
