Who We've Worked With
Case Studies
Ballast Water System Upgrade - Vertical Inline Centrifugal Pumps
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. Ballast water pumps transfer seawater to and from the ballast tanks in order to add weight to the ship for stability, so reliability is key.
Marine Gas Oil Conversion for Ferry Operator - Screw Pump
A UK ferry operator required a verticle inline screw pump with Lloyds approval, due to undergoing a marine gas oil conversion. The customer needed the pump in 3-4 weeks in order to meet the vessels dry docking program. Castle Pumps supplied a vertical inline screw pump in just over 3 weeks, complete with marine certification. In result of our quick response and supplying the pump within the time needed, we were also asked to supply a DN80 strainer and flowmeter suitable for MGO.
Boiler Feed for World's Largest Container Ship - Type Approved Centrifugal Pumps
Castle Pumps have been specifying and supplying pumps for the marine market for several years, and therefore have expertise and knowledge when it comes to marine enquiries. The world's largest container ship in 2012 contacted Castle with an urgent enquiry, requiring two boiler feed pumps. Castle Pumps were able to select a model that matched their requirements and dispatch them in just 9 working days!
