The Seakeeper 40 is shipped with the cooling circuit filled and ready for use. The Seakeeper 40 requires connection to a raw water pump, referred to as the seawater pump, to cool the closed loop cooling circuit on the unit.  The required seawater flow through the Seakeeper 40 heat exchanger is between 13 – 15 GPM (49.2 – 56.8 LPM) when the on-demand cooling system requires cooling. Prior to operation, confirmation of glycol level is recommended.

Seakeeper offers a compatible self-priming DC Seawater Pump and electric isolation valve (P/N 30628) prewired for the Seakeeper 40 Installation and covered under the standard Seakeeper warranty. The pump conforms to the seawater plumbing best practices noted in TB-90947. See Drawing No. 30628, SeaFlo® Seawater Pump Assembly, and the Seakeeper Options and Accessories Price List for details.
