Product Description

Lowara e-NSC series

Horizontal centrifugal electric pumps equipped with ie3 motors

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.
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:

EXTENDED SHAFT
Close-coupled by means of an adaptor bracket with an impeller keyed directly to the special motor shaft extension.

FRAME MOUNTED
Flexible-coupled with bracket, support, flexing coupling (special version with spacer on demand), aligning and anchoring base.

STUB SHAFT
Rigid-coupled with a bracket, an adaptor and a rigid coupling keyed to the standard motor shaft extension.

BARE SHAFT PUMP
Version without driver suitable to be coupled with a standard electric motor.
