WebHistory. The first gasoline pump was invented and sold by Sylvanus Bowser in Fort Wayne, Indiana on September 5, 1885, pre-dating the automobile industry- It was commonly used to dispense the kerosene used in lamps and stoves.He later improved upon the pump by adding safety measures, and by adding a hose to directly dispense fuel into automobiles. Web1. Definition. What is the pump head ? The pump head is the actual pressure developped by a pump. It is expressed in vertical m of liquid (water for pump characteristics graphs). The pump head takes into consideration the difference of pressure in between suction and discharge but also the speed difference, all converted to m of liquid. 2.
