  • Useful information on Gear Pumps - Michael Smith

    2018-12-12 · Flow and outlet liquid pressure can be controlled by varying the air pressure. To calculate discharge liquid pressure, multiply the air pressure by the ratio shown in the table. Pumps are self- priming, which means they create a suction force to draw liquid upward to fill the pump chamber.

The strength of the motor within the pump determines the strength — stronger motors create higher pressures. The shape of the nozzle is the final factor; narrow and constricted nozzles create higher pressure than wide or open ones.
