Pumps and piping, a very common misconception people have when looking at pumps is to go for maximum pressure however we will show you that 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.

Pipe Diameter Flow Rate M3/Hr  Pressure Loss Over 1,000m 
108mm (4") 125 9.07 bar
  150 12.63 bar
  175

16.72 bar

131mm (5") 125 3.45 bar
  150 4.80 bar
  175

6.36 bar

158mm (6") 125 1.45 bar
  150 2.02 bar 
  175 2.67 bar
  250 5.11 bar

 

6 mm was added to inside diameters of pipe diameter to allow for stretching. Figure will vary depending on dry matter of material being pumped. Above figures are for water.

It is easy to see from the above 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. diesel and wearing out pumps creating this pressure then losing it due to a wrong hose and coupling choice.

So if you study the above, it will very quickly become apparent to avoid smaller hoses where possible
