Características
- Standard NEMA motors on all pumps.
- Integral thrust bearing on 5 HP and larger pumps to handle axial thrust loads.
- Liner ring is a self-aligning, floating design constructed to prevent swelling at high temperatures.
- Tungsten carbide lower pump bearings and sleeves are standard construction for all services, providing maximum operating life.
- Direct drive pump and motor shafts are keyed for positive, reliable power transmission with no adjustments necessary.
- “Flexible” floating outer casing allows for thermal expansion in hot water applications, preventing deformation due to pressure fluctuations.
- Anti-erosion measures a dish-shaped insert is fitted to the intermediate casing designed to promote smooth flow and prevent high velocity areas that accelerate erosion.
- Square-edge six spline shaft (VMS 03-18) or twelve spline shaft (VMS 32-64) provides positive location and drive of impellers eliminating wear.
- Dimensions & flanges installation is to market accepted dimensions for easy upgrade of existing installations.
- Mechanical seal Silicon Carbide/Carbon/FPM mechanical shaft seal.
- Positive Sealing O-rings between intermediate casings provide positive sealing and increased efficiencies.
