China Dredge Pumps Factory said it is sorry to say there is no simple answer. A valid analysis made with the goal of forecasting how far a dredge pump can pump must take into account the following variables:
• Pump efficiency.
• Available horsepower.
• Available pump speed
• Pipeline diameter.
• Static lift.
• Dredge Suitability.
• Slurry density (Rate of production).
• Feed rate regulation.
• Solids particle size & distribution.
• Availability of pumpable solids.
All of these factors influence a dredge pump's maximum pipeline “range”.
Some of them are design variables and others are operating variables.
Design variables are those that were made constants by the choices made when specifying the dredge/pipeline/process plant.
Operating variables such as density, feed rate and velocity can be converted to constants by the effective use of instruments and controls.
Uncontrollable factors—availability of pumpable solids and particle size and pump distribution—are unique to each deposit and may vary widely. Hopefully, the dredge pump is equipped to deal with these factors and maintain a satisfactory rate of production. If not, a more effective digging device may need to be employed.
