The Naval Facilities Engineering Service Center (NFESC) has successfully completed the Phase 11 demonstration of a seawater hydraulic-powered CCN-150 transfer pump. The objective of this demonstration was to compare performance parameters for the CCN-150 transfer pump powered by a Fenner F60 seawater motor against the transfer pump powered by the standard Rexroth oil hydraulic motor. Tests of the seawater hydraulic-powered CCN-150 transfer pump were conducted between 46 and 51 horsepower due to available power sources. Scaling of the transfer pump performance curves showed that the seawater hydraulic-powered CCN-150 transfer pump achieved equivalent performance to the oil hydraulic-powered CCN-150 pump system, confirming that a seawater hydraulic design for the CCN-150 transfer pump is practical using commercial components.
