Castle Pumps received an enquiry from a new customer who needed to upgrade their ballast water system, in order to meet the 'Ballast Water Management Convention 2017' regulation. We supplied Azcue cast bronze pumps to ensure that all wetted parts that come into contact with the seawater are non-ferrous and therefore would not corrode.
