How a Diaphragm Pump Works

How a Diaphragm Pump Works

Double diaphragm pumps operate using an oscillating positive displacement principle. The pump consists of two main fluid housings and a central air control section. Inside each housing, a flexible diaphragm is mounted vertically and connected to a shared shaft. As compressed air enters and exits the air chambers, the diaphragms move in a coordinated push pull motion.

Predicting Vertical Motor Resonance: A More Accurate Method to Protect Equipment

27.11.2025 -

Vibration in rotating machinery is a leading cause of premature failure, costly downtime, and safety hazards. For operators of vertical motors, one of the most important vibration-related concepts to understand is reed critical frequency (RCF). This natural frequency of a motor system plays a central role in determining whether a motor will operate smoothly or succumb to damaging resonance conditions.
