Nexus' ISO Close-Coupled Pumps

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.

PRINCIPLE OF OPERATION

Centrifugal pumps use the transfer of rotational energy from one or more impellers to the fluid to increase its velocity and pressure. The fluid is fed into the pump, hitting the eye of the impeller. Here, fluid is rotated, thereby gaining more speed. The fast rotation of the impeller causes the fluid to be deflected to the tips of the impeller and falls off to the volute. Here the fluid loses speed but gains pressure, causing it to be directed towards the pump outlet.
