Nexus ISO end suction, close-coupled centrifugal pumps are single-stage and designed according to ISO 2858 standards and are interchangeable with other ISO pumps. They use the standard TEFC foot and flanged electric motors and are particularly suited to confined spaces where long-coupled units may not fit. The pumps eliminate costly couplings and the alignment problems sometimes associated with long-coupled models. With these pumps, users also get many options for construction materials, pump discharge positions, and operating range.
