Castle pumps received an enquiry from a new customer in the UK that wanted to find a robust sea water transfer pump for their crab vessel.


We selected an Azcue MN100/160 close coupled centrifugal pump in order to fulfill the duty requested by the customer, and so that the materials of the pump were able to resist the fluid - meaning the pump will be long lasting and robust. The selection for the pump is the most important part of the process so having the correct information is vital to ensure that the customer not only gets a pump that works, but a pump that is efficient in saving money in power and spares over the lifetime of the pump. Both sea water pumps were manufactured in Spain and delivered in fewer than 5 working weeks.
