The RNI range are Horizontal Centrifugal Pumps with axial suction and support for horizontal shaft bearing, according to Ex DIN 24255 / NF E-44111, and impellers of hydraulic design optimized for high performance. This standardization allows to unify the same part to a large number of pump sizes, thus facilitating the service of spare parts, by reducing the variety of parts. Its design allows the revision of all rotating and internal parts without the need to disconnect the pump body from the suction and discharge piping. It is also not necessary to move the motor if a coupling sleeve with spacer is provided.
