Product quality means attention to details





quality - small Thanks to the self-cleaning advantages of the impeller and volute design, N-Pumps offer new possibilities for cost-effective operation in a wide variety of applications. These include pumping:
Motor
Squirrel cage, high performance induction motor, specially designed and manufactured by ITT Water & Wastewater for submersible use. Stator windings are trickle impregnated in resin to class H insulation and rated at 180°C (355° F) allowing for up to 30 starts per hour.

Shaft
A short overhang of the shaft virtually eliminates shaft deflection. This results in significantly increased seal and bearing life, low vibration and quiet
operation.

Seals
Patented GriplocTM mechanical seal design. Two independently working mechanical seals for double security. Designed, patented and manufactured by ITT Water & Wastewater. Seal wear protection Spin-outT is a patented design that protects the outer seal by expelling abrasive particles from the seal chamber.

Oil housing
In addition to lubricating the seals, the oil filled compartment diffuses heat from the motor and the
bearings. The housing also provides additional security against penetration
by liquids.

Monitoring
Thermal sensors embedded in the stator windings help prevent overheating. Leakage sensors in the
stator and oil housings, together with external monitoring equipment, are available as options.

Cable entry
The cable entrance is designed to incorporate both a seal and a strain relief function. International
standards approvals All pumps are tested and approved in accordance with national and international standards (IEC 34-1 CSA). They are also available in explosionproof versions - Factory Mutual and European Norm (FM and EN) approvals.
