Product

NW20- 3021 3043 -V ( H) -50Hz

Description

Features / Benefits
Impeller

  • Ductile Iron Casting for Superior strength and long Life
  • Recessed Design-Provides non-overloading Performance
  • Recessed Design-Reduces bearing load / Increases Bearing Life
  • Recessed Design-Prevents clogging of Volute & Discharge
Shaft Seals
  • Full Mechanical (Silicon carbide / Silicon Carbide ) with Secondary Lip Seal in Tandem.

Motor
  • Permanent Split Capacitor design for Single Phase models Features Lower Starting Currents, While maintaining Excellent Starting Torque
  • Capacitor is mounted internally-No External start switches or Capacitors
  • Thermol overload is mounted directly on the windings in the single Phase models, for Maximum Temperature sensing
  • Stator is Pressed into the cast Iron motor Housing for excellent stator alignment and for superior Heat transfer from the Windings.
Oil-filled provides
  • Constant Bearing Lubrication.
  • Maximum Motor cooling (Conducts heat from Motor Windings to Fluids Being Pumped)
  • Helps provide even heat distribution, throughout the motor Housing, Aiding to eliminate(Hot Spot Zones) as seen in Air filled motors, Air has a very low Coefficient for Tranferring heat.
