Marine & Offshore

This UK based Marine Dredging company required a self-priming centrifugal pump, in cast iron to save costs, for transferring sea water containing small amounts of sand. We selected a horizontal self-priming centrifugal pump with a cast iron casing and bronze impeller from our CA range, capable of allowing 10% passage of sand content in the sea water.

This existing customer needed to upgrade their fire pump system on board their vessel and decided to contact us due to our reliability with past projects we have done for them. Due to the extensive knowledge and experience we have on the marine sector, Castle Pumps were able to meet the customers specific requirements and provide them with an ideal pump which was manufactured and marine certified in fewer than 8 working weeks.

A private boat owner was installing a reverse osmosis system aboard their vessel and required a high pressure pump for the system to convert sea water into fresh water - at a duty of 8.8 L/min at 35 Bar. Due to our wealth of experience with reverse osmosis systems; we were able to select a plunger pump that matched their requirements.

Castle Pumps not only supply individual pumps, but also complete pump packages including ancillary items. The customer needed a portable, self priming, variable speed water supply pump package which could be powered by the clients vessel whilst in a dry dock. By designing, building, testing and supplying the customer with the pump package, it enabled the vessel to be completely autonomous in the supply of fire water, AC and refrigeration services.

Castle Pumps have a wealth of experience supplying pumps to the marine industry, and we ensure that we match the features of the pump to the specific application at hand. This case study demonstrates this, as we knew that for guaranteed reliability for emptying a sump of sea water and waste solids, a pump with vortex non-clogging impellers would be required and the material would be best in bronze to avoid corrosion from the sea water.

Castle Pumps customise and engineer pumping solutions when required, to ensure that they match the customer's bespoke requirements exactly. In this case study, we put together a ready to use skid mounted pump system complete with pump, motor, belt drive, guard and steel base to meet their requirement for a high pressure, low flow solution.
