SEP GNM 

SINGLE STAGE, END SUCTION CLOSE COUPLED PUMPS

SEP GNM series are horizontal shaft, single-stage end suction pumps with radial or mixed-flow closed impellers. The series includes 16 models, designed according to EN 733 standards for compatible flange and base dimensions. These close-coupled pumps use motor-supported shafts and mechanical seals flushed by the pumped fluid, ensuring reliable and efficient operation in industrial and water applications.

SEP GN HW

SINGLE STAGE, END SUCTION HOT WATER PROCESS PUMPS

The GN HW series consists of reliable, single-stage centrifugal pumps designed to ISO/API (OH1/OH2) standards for critical industrial applications. These pumps feature an end-suction, closed-impeller design and are built for longevity with interchangeable spare parts. Key technical advantages include versatile material combinations, API 682 mechanical sealing systems, and a "back pull-out" design, which allows for the removal of the impeller and shaft without disconnecting the pump body from the piping.
