4. Suction side (inlet)

5. Discharge side (outlet)

The principle of operation of the pumping action in Tapflo hose pumps is achieved by pinching a circular loop of rubber tube with two diametrically opposed rotating wedges. Due to the rotational movement, the fluid in the tubes is pushed ahead of each wedge. When each wedge reaches the end of the loop, the hose is released and the wedge rotates n to the start of the loop to begin a new cycle.

As the wedge releases the reinforced tube, it immediately returns to its original shape, there by ensuring positive suction and priming. This construction makes it a smart and effective choice for a wide range of pump applications.

 

Typical application

hose-pumps-slideshow-2.en

The pump housing is partially filled with lubricant, thereby allowing smooth running of the wedges on the tube. The pump fluid is only in contact with the inside of the tube and can therefore be of an aggressive nature and/or contaminated with particles. PT pumps are commonly used for:

Industrial waste water, waste sludge treatment, flocculent dispersions, flocculated waste, lime liquor, sludge and slurries, ceramic slips and paste, clay suspension and compounds, cement slurries, concrete pumping, ore slurries and leaching pulp, metallic salts, crystallized suspensions, black liquor foam, filter press applications, cosmetics, pharmaceuticals, etc.

How to use the pump curves

  • 1. Select the required flow. This gives you the required pumpspeed.
  • 2. Move upwards to the calculated discharge pressure.
  • 3. Move to the left for the installed motor power.
  • 4 . Determine the fluid’s max. temperature.
  • 5. Move to the left to the calculated discharge pressure.
  • 6. Move downwards to determine your maximum allowed pump speed for the fluids temperature.
