Vertical Multi-Stage Pumps

Features: 

1.  Air vent in casing cover - allows proper venting, preventing air entrapment and dry run
2.  Liner ring - self-aligning, floating design constructed to prevent swelling at high temperatures
3. Tungsten carbide lower pump bearings and sleeves - standard construction for all services, providing maximum operating life
4. Direct drive - pump and motor shafts are keyed for positive, reliable power transmission with no adjustments necessary
5.  "Flexible" floating outer casing - allows for thermal expansion in hot water applications, preventing deformation due to pressure fluctuations
6. Anti-erosion measures - a dish-shaped insert is fitted to the intermediate casing designed to promote smooth flow and prevent high velocity areas
