Wilden Bolted Design on Advanced Series Air-Operated Double-Diaphragm Pumps

Global demand for essential products like water, gas and oil is growing, which means that pipelines and processing plants such as pressure vessels are getting bigger. To ensure continuity of supply and minimise downtime, maintenance teams need to gain safe and rapid access to critical plants that require servicing or repair.

For several years, a pump at the largest production site in Kingsport, Tennessee, USA had been causing the US chemical company Eastman problems: it was operating on a process with water at high temperature and low pressure, generating the entrainment of more than 10% gas by volume in the form of water vapor. This often caused the pumps used to fail.

Water hammer is a pressure wave that occurs when liquid flows through a pipe and there is a sudden change in the liquid velocity.
