High pressure gear pumps produce high discharge pressures and metered flow because of positif displacement when discharge line is prestricted or completely closed an external relief valf is required to prevent motor overload and line breakage .
All gear pumps are self-primming allthough a foat valve is recommendet. Capacity varies directly with motor speed. The power required varies directly as capacity and pressure.
Because of the close internal tolerances pump be protecteal with a suitable filter loss in suction line must not exceed 0,5 kg/cm2
