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.

Control and Pumping Speed: Matching Capacity to Demand for Maximum Efficiency

04.09.2026 -

One of the most effective ways to improve the energy efficiency of a vacuum system is to ensure that the operating capacity of the vacuum pump is aligned with the actual needs of the process. A vacuum pump that runs at full speed when the process demand is low wastes energy and can cause unnecessary wear on equipment, reducing service life. By implementing intelligent control systems and variable speed drives (VSD), energy consumption can be significantly cut, leading to lower operating costs and a reduced carbon footprint.
