This is the sound of an old-fashioned rod-type well pump, which, until a few years ago, were quite prevalent on the island where I live. The pump consists of a piston at the bottom of a pipe that extends down to below the water level in a well. The piston is linked, via a long series of wooden rods, to a motor-driven crank. The rods move up and down inside a pipe, each piston stroke bringing water to a pressure tank in the well-house. The motor drives the crank through a heavy gear-box, which makes the characteristic groaning sound you hear. When water is being lifted up the pipe, the pitch is low, then, as the piston plunges downward, the gearbox races, generating a higher-pitched sound. You can hear the sound of the wooden rods banging against the pipe extending down inside the well, the groan of the gears, the subtle note of the motor, and a click at each cycle, whose source I'm uncertain of. Possibly it's due to play in the crank linkage. Sad to say, this wonderful pump was replaced by a silent submersible type pump not long after this recording was made. But at least you don't have to pull out the rods every couple years to replace the leathers on the piston!

The recording was made in 1985 with a Sony Walkman Pro cassette recorder and an Audio-Technica AT9400 mic.

    Amazing sound! I'm using it for old machinery in an abandoned sewer system in a GZDoom level. Thanks!

    many thanks KG Jones, for that sound, which I overlay with oscillating water spilling sounds to give an impression of old water well pumps from 18. and 19. century.
