AXIAL FLOW PUMP

DESIGN

The Axial-Flow pump generates flow by the thrust or lift action of rotating axial vanes of the impeller. The pump has an elbow that directs the flow through the suction and out the discharge end of the pump. It can be used in the top or end suction configuration depending upon the need and Flange dimensions, bolt circle, and holes comply with ANSI B16.5, 150#. The back pull out design (up to 14" size) allows for easy maintenance and repair as the rotating element may be removed without disturbing the pipework. The pump has wear rings as standard and lifting eye on bearing bracket.

PUMP SELECTION

  • For Pump selection, the hydraulic performance curves should be used.
  • These curves are based on water 20°C and specific Gravity equal to 1.0.
  • NSPH valves are indicated on the performance curves. At least 1.5 meters must be added as a safety margin.
