Seawater service pumps for circulation and transfer

As the UK agent of marine type approved pump manufacturer Azcue, Castle Pumps have been supplying vessel owners, ship management companies and marine engineers with marine type approved seawater service pumps for over 15 years. Whether you’re looking for a general seawater pump for a range of service requirements, or a model for ballast, cooling, firefighting or bilge, we will have a proven solution. As standard, we supply our seawater pumps cast in bronze for compatibility with the salt content in seawater, a more cost-effective and available alternative to stainless steel. When it comes to pumping seawater there is no one size fits all solution, it depends upon the actual service the pump is providing. That’s where Castle Pumps as a specialist marine water pump provider are here to help you.
