Axial-Flow Pump
APPLICATION
The JEC Axial Flow pump is unmatched in the industry for high volume / Low head pumping requirements, especially when corrosive and/or abrasive solutions are involved. Mainly used in the followingapplication:
- Evaporator and Crystallizer Circulation
- Phosphate, Soda Ash, Potash and Sodium Chloride Processing
- Polypropylene Reactors, Xylene application
- Black Liquor Evaporator, Chlorine Dioxide Generators
- Sewage Digesters
- Raw Water pumping, Flood control, Marine Ballast transfer
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.
DESIGNATION
- Model / type - AF
- Suction & Discharge Diameter (inch) - 14
CONSTRUCTION
Horizontal non-self-priming pump with back pull out design (up to 14" size & bigger size available on request). The "back pull out" design allows for the maintenance of the pump without disturbing the pipework connected to the casing, or the pump alignment.

ACCESSORIES
- Direct
- V-belt, Pulley Drive
- Gear Box Drive
Base plates for electric drives are available in two variants of styles. Standard: fixed and grouted directly to the foundation Anti-vibration: rigid base plate on rubber mounts.
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.
