List of products by manufacturer Charles Austen / BlueDiamond

Originally founded and trading as Charles Austen Pumps Ltd, BLUEDIAMOND has been manufacturing pumps for almost three quarters of a century. ​

It is common belief that the company's original founder 'Charles Austen' invented the first ever compact diaphragm pump following the first world war, using leftover army boot leather as the diaphragm material. This obviously spawned an industry that the company continues to innovate consistently today. Charles Austen Pumps holds a vast number of patents and has championed design shifts that have dragged the seemingly stale pump manufacturing industry into the future.
