Diaphragms for pneumatic pumps

Compressors, Pumps, and Pipeline Fittings

Pneumatic diaphragm pumps are used widely in the national economy. A “weak” component of such pumps is the diaphragm, upon which depends the duration of continuous operation of the pump. The service life of the diaphragm depends on the design and materials of the diaphragm, temperature, and corrosiveness of the pumped medium. In this article, the designs and materials of the diaphragms are examined, calculating formulas are given for assessing the level of deformations of the diaphragm, and the level of allowable deformation is analyzed. The results of experimental development of single-layer and multi-layer designs of diaphragms made from polyurethane and rubber reinforced with high-strength fabrics for pumps with delivery capacities ranging from 0.5 to 40 m3/h are analyzed.
