Dear all,

I am using a back pressure regulating valve in the pump recycle for maintaining constant pressure in the pump discharge.

Pump is used for water spray system.Pump rated point is 15.2 m3/hr at 95 m.

On what basis i have to provided set point to back pressure regulating valve in order to maintain the constant pump discharge pressure?

chandru,

The set point of the PCV should be the corresponding pressure value of the pump minimum flow.
