The Humphrey pump is a large internal combustion gas-fueled liquid piston pump. The pump was invented by H. A. Humphrey and first presented in paper to the Institution of Mechanical Engineers on 19 November 1909.[1][2][3] A pump capable of pumping 250,000 gallons per hour to a head of 35 feet was exhibited at the 1910 Brussels Exhibition, where it was awarded two Grands Prix, for both engines and pumps.[4]
A small number of pumps were built between 1906 and 1925 for use in large-scale water supply projects.[1][2] Although only a few pumps were built, some continued in service into the 1960s.[5]
