1 Lenntech Tel Fax NOCCHI VLRI/X HIGH HYDRAULIC EFFICIENCY, ENTIRELY IN AISI 34 STAINLESS STEEL (VLRI) OR AISI 316 (VLRX), STANDARDIZED MOTOR The VLRI/X series offers vertical multi-stage centrifugal pumps with in-line suction and delivery ports. Directly coupled with an electric motor. Completely in AISI 34 STAINLESS STEEL / 316 for sea water and special applications. Non self-priming. APPLICATIONS Water supply Pressure increase system Irrigation High pressure washing Fire fighting systems Boiler supply Liquid transfer MOTOR Electric asynchronous motor with closed casing and external ventilation. The main dimensions are in line with the provisions envisaged by the standards DIN and IEC. Construction design: Up to 4. Kw V18. From 5.5 Kw V1. Insulation class F. Protection rating IP 55. Maximum ambient temperature: 4 C. Rotation speed 29 rpm. Oversized bearings for optimal load support.
