A very common misconception people have when looking at pumps is to go for maximum pressure. However, this is not necessarily the case.
If you want the highest amount of slurry to go through a pipe, a better option is to look at the hose size to reduce the friction rather than the pump.
Slurryquip calculates out the most efficient method to achieve high output machines while reducing fuel and pump wear. We aim to be more efficient to save money wherever possible; this works out more profitable for the farmer and the contractor.
Here is a breakdown of how different pipe diameters affect flow rates and pressure loss over 1,000 meters:
Slurryquip offers systems for both farmers and contractors but recommends as much 5” and 6” hose as possible due to much-reduced friction loss when compared to the previously more popular 4” hose.
Benefits of Larger Hose Diameters:
Reduce wear
Spread faster
Pump thicker slurry
Dramatically reduce fuel usage
Less stage pumping required
Increase output by 120%
Decrease cost to pump by more than 50%
Note: 6 mm was added to inside diameters of pipe diameter to allow for stretching. Figures will vary depending on the dry matter of material being pumped. Figures above are for water.
System Comparisons:
It is easy to see from the figures that high pressure is not the answer, but hose diameter is if you want high outputs.
Slurryquip has embraced this information and has developed a much more efficient umbilical system because of it. Right down to the smoother couplings, we try to save as much of our pressure as we can. This reduces diesel consumption and pump wear by avoiding creating excessive pressure that is then lost due to the wrong hose and coupling choices.
