The Fleming Hydro-Ram


Despite the complex hydraulics of the Fleming Hydro-Ram, its operation can be outlined simply; first falling water from the source...a stream or artesian well...is funneled into a drive pipe connected at (A) until a necessary minimum volume is achieved. Water flows down the drive pipe until it reaches a specially designed poppet valve (B). At this point water escapes through the waste valve opening until it builds up enough pressure to seal the opening of the poppet.

Since the flowing water in the drive pipe can no longer escape through the waste valve opening, it is forced to open a mid-range inline check valve (C).

Water continues past the check valve and starts compressing the trapped air in the vertical compression chamber (D). Water continues to push against the air in the chamber until the compressed air cushion acts like a piston, pushing water back down and out of the air chamber.

This action, in turn, closes the one-way check valve causing water to be forced out of the ram and up the delivery pipe, which is attached at (E).

Meanwhile, the closing of the check valve creates a slight vacuum or suction which permits the waste valve poppet to drop open again. This allows water from the drive pipe to escape through the waste valve opening, creating a new cycle. There are about 60 such cycles per minute.
