Testing original 1930s engine-driven pump

How we innovated to help a UK water company to test its largest engine-driven pump and verify pump efficiency improvements following a major refurbishment

One of our client’s most important pumping stations serves many square miles of domestic London. The station has six electrically driven pumps up to a capacity of 2 tonnes of water per second. Using FREEFLOW, we tested the company’s 1930s diesel-driven units, which had an original duty flow rate of 5 tonnes of water per second.
