Flowserve-Flowserve-Double Case Pumps - APKD

Double Case Pumps - APKD

BRAND: Flowserve

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.

Features & Benefits
  • 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
  • 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
