A Grundfos end-suction long-coupled single-stage pump is a type of centrifugal pump designed for large-scale industrial applications. It features a single impeller and a long-coupled design, which allows for easy maintenance. Additionally, its back pull-out design enables the removal of the motor, coupling, bearing bracket, and impeller without disturbing the pump housing or attached pipework. The suction of end-suction pumps is typically axial, while the discharge is radial, forming a 90-degree angle.
