Past Self Priming Centrifugal Pump Project

As suppliers of centrifugal self priming pumps for well over 10 years, Castle Pumps are regularly helping industrial and marine clients with quality solutions.

Read our case study and find how we helped one of our clients, an engineering consulting company, that needed self-priming seawater injection made by stainless steel 316, rather than the recommended material of bronze. We chose Azcue long-coupled self priming centrifugal water pump known for their reliable performance, low-cost maintenance, and seawater compatibility.
