Nexus’ ISO Long-Coupled Pumps

Nexus’ ISO Long-Coupled Pumps

The nexus range of single-stage end-suction centrifugal pumps that are designed to the International Standard ISO 2858 is preferred by many Australian industries for their rugged construction and reliable performance. These heavy-duty workhorses offer high flow and high-pressure capabilities and can be used for a wide range of applications in the industrial, municipal, and marine markets. They are efficient at pumping low viscosity clean or slightly contaminated fluids without the presence of large or fibrous solids.

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.
