Pump specifically designed for delivering water - adjusts to varying operating conditions using non=return valves and a hp relief valve

摘要

A piston (2) operates in a cylindrical pump housing (1). At the end positions of the piston (2), pairs of pipes (3,4,5,6) with non-return valves (7,8,9,10) are connected to the pump housing (1). There is an outlet (11) at the point where the first pair of pipes (3,4) connect, and a supply pipe (12) at the junction of the second pair of pipes (5,6). A HP relief valve (15) has connections at the junctions of the first pair (3,4) and the second pair (5,6) of pipes. USE/ADVANTAGE - A reliable and durable pump which can be used for high or low output at high or low pressures.
