Hydraulic Submersible Pump
Hydraulic Submersible Pump
(OP)
Hi All,
Can some please give me some advice on a hydraulic submersible pump. My knowledge of pumps is quite limited.
I'm going to be using the pump as part of a jet washing system that will be used to clean the dirt from the walls of a large concrete reservoir. A nozzle will be attached to the discharge side of the pump. The pump will be operating at a depth of 10 meters (1bar). The pump will be using the surrounding reservoir water as the supply.
This is were I'm getting a bit stuck. How is the total head calculated for a submersible pump?
Thanks
Mark.

You have 10 meters of suction head (32.8 ft). The required pressure at the spray washer + pipe friction headloss minus 10 meters of suction head equals the Total Pump Head Required

RE: Hydraulic Submersible Pump
The experts above are absolutely correct in needing a reciprocating pump if these walls need to be absolutely clean; as clean as say, if you were power-washing your driveway.
On the other hand, if you were just trying to clean large clods of mud off of these walls, and the square footage was really large......say like cleaning a large mud pit on a drilling rig....then you would benefit from having the volume of a centrifugal. You can get a really nice stream of water from a submersible with a good nozzle on the end of a hose.
What you need to look at in either case, especially the centrifugal, would be the pump curve. Do you have that, and can you share?
