The combination balances wear resistance and fluid compatibility, providing durable sealing performance across common industrial coatings.
Yes—check the displacement rod for scoring, seats for pitting, and bearings/bushings for excessive play. Replace any damaged parts to avoid premature failure of new packings.
No. A repair kit restores sealing; it does not alter the pump’s mechanical ratio or displacement. Performance should return to spec if all components are within tolerance.
