Abstract

1442956 Reciprocating pumps O TUCHENHAGEN 13 Jan 1975 [17 Jan 1974] 1334/75 Heading F1A A method of silencing an hydraulically-actuated diaphragm pump, e.g. for waste water, comprises introducing a gas, e.g. air, through a valve 6, 8 into the liquid column in actuating chamber 9 following the engagement of diaphragm 4 with perforated plate 5 during its suction stroke, so that the continuing return movement of actuating piston 2 cannot cause partial evaporation of the liquid column, and discharging the gas through a valve 12, 14 during the subsequent delivery stroke. The spring-loading of valve 6, 8 is adjustable. The liquid column may be clean water.
