• Black anodizing Aluminium casing;
• Simple and robust spring return mechanical diaphragm pump; • Black anodizing aluminium casing; (XRN Series only)
• Low cost, due to reduced number of components; • Technically advanced hydraulic diaphragm spring return pump;
• Uses mechanically actuated diaphragm to combine the characteristics • Combines the simplicity and economics of the spring return with the
of a plunger pump (linear flow rate) with the sealing advantages of a advantages of the hydraulic diaphragm using an innovative
diaphragm pump; mechanically actuated oil replenishing system;
• Suitable for batching operation; • Build-in relief valve on the oil circuit to protect the pump against over pressure;
• Minimum maintenance required. • Can be used in both process and service applications;
• ATEX STD compliance (94/9/CE), • Minimum maintenance required.
