  1. #1

    pump discharge pressure and orifice

    Can we use orifice to maintain the discharge pressure and how we calculate the desired dia of orifice with required discharge pressure.
    Please help

    Dear Washoo
    Pump discharge orifice is generally applied to get % head rise to shut-off (for pumps having flat performance curve). Discharge orifice can not maintain discharge pressure of pump. What exactly you are looking for?

    Re: pump discharge pressure and orifice

    We are using roto jet pump of discharge pressure at 1200 psig by manually closing the discharge valve. To maintain the discharge pressure we have to install automatic / manual pressure control valve at the discharge of pump. We want to replace the pressure control valve with orifice. Is it possible and how?
