Double Case Pumps - APKD

• 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

• Flowserve
• Hydraulic Institute
• AWWA E103 ISO 13709 / API 610
