Water Intake Hose

Another thing that is pretty annoying besides boulders is keeping the amount and quality of water for the intake hose. Due to the fact that the suction nozzle continues going further into the water, the amount usually not the problem in this case.

Figuring out the amount that is needed by centrifugal pump on its own is not an easy thing to do since most people are not able to relate gallons per minute to a really definable form. Think about a 150 gpm pump hooked onto a twenty gallon gas tank of a car. It would empty it all out in 7and half minutes every minute. The same is true of a barrel that is two and a half feet in diameter and four feet deep you would have to fill it up every minute in order for your pump to continue working. That is a great deal of water and it simply does not cross anyone’s head that a little hole in stream that is moving slowly is not going to supply enough water for a dredging operation.

If you were in the field try to picture a stream of water flowing by the foot valve as two foot wide and two feet in depth as well. a float in this type of stream should move around seven feet in around one minute in order to provide the pump with a capacity of 150 gpm.

Quality has to do with the type amount of sand that is suspended in the water and that is getting pulled inside the centrifugal pump. In ideal situation there would not be any sand, however in reality there is in most cases a little amount moving around in the stream. Obviously when sand passes through the centrifugal pump it causes the impellers to grind down. In most cases the pumps are able to handle little quantities of sand and function well for years. However on the other hand, if a big quantity of sand gets inside of a pump it can wear down the impellers very quickly and in some extreme cases it can cause damage in just a few hours. In order to avoid this damage from occurring you will need to make sure to maintain the quality of the water that goes inside of it.
