TRANSFER SECTION OF AIR-DRIVEN DIAPHRAGM PUMP SYSTEM Russian patent published in 2016 - IPC F04B43/08 

FIELD: engines and pumps.

SUBSTANCE: invention relates to transfer of fluids and may be used in oil, petrochemical, pharmaceutical, chemical industries etc. Claimed section comprises tubular case with end flanges and through radial channels, check valves and tubular diaphragm fitted therein and made of resilient material. Said tubular diaphragm is composed of a closed chamber with pipe rigidly fitted therein from one end side. Said pipe is communicated with the case radial channel. Said channel is connected from the case outer side to high-pressure pipe. Tubular diaphragm cylindrical wall features the depth varying over its generatrix and faces the intake and discharge air valves. Diaphragm wall maximum depth is maximum nearby the pipe and minimum nearby its other end. Difference in wall depth makes 15-20 percent. This section is connected with other sections, booster line and high-pressure line by end flanges via check valves. Described design ups the efficiency of fluids transfer over larger distances or height with application of high-pressure equipment.

EFFECT: longer service life.
