Surface Wash Pressure?

[sjohns4]

Does anyone know what the pressure you need to feed surface wash arms? Long story, but existing wash arms normally operated around 200 GPM, due to some piping mods there was a loss of pressure at the connection to the wash arm piping. There are a couple things we can do to increase the pressure, but I dont really know for sure how much we'd need therefore I dont know exactly what mods we should be doing?


Thanks,

Mike

The pressure depends somewhat on the nozzles that are installed. There is probably about 35 psig drop across the spray nozzles.

The typical water pressure for a rotary wash is 50 to 75 psig.
