AXIAL FLOW PUMP

Applications

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 following application:

  • Evaporator and Crystallizer Circulation
  • Phosphate Soda AshPotash 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 lifts 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, the bolt circle, and holes comply with ANSI 816.5, 1508. 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 pulls 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.

FLANGE DRILLING

ANSI B16.5,150# SORF. - Standard
DIN - Optional

CASING

The shaft is of the wet type, which comes in contact with the pumped liquid.

SHAFT

Casted or fabricated elbow with precisely machined for a minimum gap between propeller and casing. Liner type cast casing also available.

SEALING OPTIONAL

- Stuffed Packing Box
- Single / Double Mach. Seal with cartridge-type arrangement
- Other available as per request

ACCESSORIES

DRIVE

  • 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 meter must be added as a safety margin.
