When is the HP draw the greatest on a dredging project?
The power required by the pump will increase as the pipeline length increases until the full load (max. horsepower) – full speed (max. pump RPM) point is reached. Beyond that point, the power requirement decreases as the pipeline lengthens. Note: If the flow rate is higher than required to carry the slurry, it will use more HP than needed, wasting fuel. The most efficient dredging is done at the lowest velocity that will carry the maximum slurry density.
