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.
Valmet is planning changes to its manufacturing in Sweden and Poland and has initiated change negotiations in its Global Supply unit concerning the planned closure of manufacturing at its Sundsvall site in Sweden.
