e-NSC SERIES
GENERAL INTRODUCTION
The new e-NSC series is the result of the close collaboration between our customers and us; the new range has been
redesigned and improved to meet the Commercial Building Services (CBS) requirements, in terms of performances
and energy saving.
In addition the new e-NSC series can be customized to meet the needs of the Industry segment, keeping the quality
in the production and the continuous reliability and robustness in the operation.
Pump design
The new e-NSC series is a centrifugal end-suction electro-pump with single-stage (except the two-stage NSC2
models), axial flanged suction port, radial flanged discharge and horizontal shaft. The e-NSC pumps have cast iron
casing and impeller as standard but are also available in a wide range of materials, from bronze to duplex stainless
steel, to allow for various pumping needs.
The pumps are equipped with interchangeable mechanical seals, IE3 efficiency motors, and are designed with a
back pull-out configuration (impeller, adapter, and motor can be extracted without disconnecting the pump body
from the piping system).
The e-NSC series pumps are available in the following constructions:
