Past slurry pump project

Castle Pumps have been providing technical expertise when specifying pumps for waste slurries and sludges for over 15 years, but don’t just take our word for it.

Read how in this past project we working with a subsea oil and gas company, supplying a heavy duty sludge pump solution for their vessel. The client already had a progressive cavity pump onboard which worked fantastically in terms of handling the viscous waste fluid but needed a replacement due to it coming to the end of its lifespan.
