For almost 70 years, Charles Austen Pumps has worked hard to earn the trust and respect of pump buyers within various industries across the world. Our founder, Charles Austen, is widely believed to have invented the first ever diaphragm pump using the leather from left-over army boots following the first world war. Charles later went on to found the company which in the 1940s, became the first manufacturer to put pumps in the laboratory, where the equiment was used to create vaccines for diseases such as Diphtheria, Smallpox and Polio.
Since then Charles Austen Pumps has been involved in a number of huge advancements in recent human history, from the conception of Dolly the Sheep (the first ever cloned mammal) to our own world-changing innovation in the form of patented rotary diaphragm technology. Even to this day Charles Austen is revolutionizing pumping principals in a wide span of different markets.
