A “Solid” Solution to Pump Selection

From Pumps & Systems: Tests show that solid-body plastic pumps are the best choice for oscillating applications.

The demands that oscillating-displacement pumps place on their materials of construction are extreme due to the constant alternating stress to which they are subjected. In contrast to rotating machines— such as centrifugal pumps, where the load builds gradually when the machine is started and then remains constant—the components of an oscillating machine (diaphragm or piston pumps) are subjected with each single discharge stroke to continuous alternating stress between the maximum delivery pressure and the maximum vacuum in suction operation.
