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.

A global manufacturer of scented plastic garbage bags was looking for an alternative to the use of pre-scented plastic pellets. A serendipitous encounter at a tradeshow led them to a precision gear metering pump solution that gave them accuracy and consistency at the low flow rates required, while also reducing their costs and improving worker health. Yearly savings are so high that the return on investment for the pump system can be measured in days.
Seeking an alternative for costly pre-scented plastic pellets

Diffusion pump technology was developed over hundred years ago. It is still used today in many areas of research and industry to generate high and ultra-high vacuum. This is not least due to the efficient operating principle: the robust “workhorses” form hot oil vapors to transport the gas molecules out of the pump chamber and pump them out via the fore-vacuum port.
Severe-duty motors are designed to withstand the most demanding operational conditions, where extreme environments challenge equipment performance and longevity. Industries such as oil and gas, chemical processing, power generation, mining, metals, pulp and paper, water and wastewater, and cement production rely on these motors for their durability and consistent performance.
