AlphaFlo®

Vertical Froth Pumps

You can turst our expertise,technology and support service to meeting your

slurry transport requirement as always.


AlphaFlo®  A series a vertical cantilever pump completely with hopper which utilises casing and liners from the AlphaFlo A series. Designed to pump mineral froth more efficiently by de-aerating or partially deaerating the froth before it enters the pump head,utilising and included vortext princiapal

(Interchangeable with OEM Warman AF Seires Slurry Pump)

Warman AF vertical froth pump

Features:


  • Impeller. Semi-open impeller designs with vanes located on both sides of the shroud are suitable for pumping froth.
  • Metal and rubber lined pump. Totally interchangeable thick rubber or hardened metal liner.
  • Casing. Two halves radially split casing with minimum casing bolts reducing maintenance and minimise downtime.
  • Bearing Assembly.  The maintenance friendly bearing assembly has heavy-duty roller bearings, robust housings, and a massive shaft convert from AlphaFlo V sereis vertical sump pump.
  • Shaft sealing. Cantilever vertical pump no shaft seal requirement.
  • Metal and rubber lined pump. Totally interchangeable thick rubber or hardened metal liner

Specifications:


  • Size range (discharge) 2” to 18”
  • Capacities to 575 m3/hr
  • Heads to 30 m


Typical applications:


  • Froth
  • Talings
  • Flotation
  • Thickening
  • Sugar cane refining

  • WHAT FROTH FACTOR CAN YOUR FROTH PUMP HANDLE?

    • The froth pump selection will depend on the froth volume factor (FVF) and the flow rate of the slurry you need to pump.
    • It need to take into consideration the throughput of the plant and the actual stream the pump is in - concentrate or tailings - as well as what section of the flotation process the pump is installed in.

  • HOW DO I MEASURE THE FROTH FACTOR?

    • To determine the froth volume factor (FVF), you will need to take slurry samples from the suction piping, as close to the pump inlet as possible. Fill several beakers so that the results can be averaged and measure the froth column and liquid. Let it de-aerate for 24 hours and then measure again.
    • The FVF is the ratio of the aerated volume to de-aerated volume. 

  • WHAT LINERS ARE AVAILABLE FOR VERTICAL FROTH PUMPS?

    Froth contains very fine particles, and rubber liners withstand this type of wear very well, proving to be very cost-effective. We use rubber or metal liners, offering them in natural rubber, synthetic rubber options for slurries with hydrocarbon or reagents content, or high chrome white iron if required.

  • CAN I USE STANDARD CENTRIFUGAL SLURRY PUMPS FOR PUMPING FROTHY SLURRIES?

    • Mineral froth is a three-phase aerated mixture containing solids, liquid and air. The air contained in the mineral froth complicates suction conditions, often resulting in an air lock at the impeller eye.
    • Unlike standard centrifugal slurry pumps, AlphaFlo® vertical froth pumps contain a unique impeller with oversized inducer blades on each vane and a large eye. This makes the entrained air bubbles dissipate or reduce in size so that they do not inhibit the flow of the slurry.

  • WHAT'S THE DIFFERENCE BETWEEN ALPHAFLO® FV SERIES AND OEM WEIR WARMAN® AF SLURRY PUMP?

    AlphaFlo® FV series slurry parts compatible with the Warman AF slurry pumps have been rigorously reverse engineered using  2D 3D modeling. First article inspection involves comparison to OEM parts followed by fit testing. All impellers have been performance tested to certify them against OEM performance.
