  • Useful information on Gear Pumps - Michael Smith

    2021-2-9 · The final step in a pump system is discharge pressure. This pressure is influenced by the amount of material in the system; if the system is low on material, the pressure will likely be lower, but the majority of the value is independent. A pump’s discharge pressure is generally determined by two main factors: pump strength and nozzle design.
