THIS Hydraulic Ram (Model: FM 39) comprises a epoxy coated steel base incorporating pulse and
non-return valves and a supply reservoir on a stand which is fed by the Hydraulics Bench. An air vessel
above the valve chamber smooths cyclic fluctuations from the ram delivery. The weights supplied may
be applied to the pulse valve to change the closing pressure and hence the operating characteristics. If flowing
water is suddenly brought to rest in a long pipe, a phenomena known as water hammer occurs, wherein a
pressure wave travels along the pipe. This principle is used in the hydraulic ram to pump water.



Due to the continuous development of our products, the goods supplied may vary in detail to that illustrated on our website.
