APKD Double Case Pump

Brand: Flowserve Corporation

The double case APKD features an innovative, double suction impeller in a true twin-volute design that produces more flow and higher head at lower NPSHR and can operate at higher speeds than conventional vertical turbine pump models.
  • Broad Hydraulic Versatility Through A Series Of Impeller Design Options Enables Better Hydraulic Fit For Each Application.
  • The Result Is Lower Energy Consumption And Operating Costs.
  • Double Suction First Stage Impeller Reduces NPSHR And Meets Hydraulic Institute Standards For Suction-Specific Speed.
  • This Design Means A Shorter, More Rigid Pump, Providing Freedom From Cavitation Over A Wide Operating Range.
  • Double Volute Design Minimizes Radial Loads, Extending Bearing Life.
  • Rigid, adjustable flanged coupling maintains accurate pu
  • Suction Can Creates Optimal Hydraulic Conditions Through The Suction Flange Inlet Into The Suction Bell.
  • Rigid, Adjustable Flanged Coupling Maintains Accurate Pump-Motor Alignment, Provides Proper Impeller Clearance Adjustment And Facilitates Seal Maintenance.
