The Seakeeper 9 is shipped with the cooling circuit filled and ready for use (See Figure 29). The Seakeeper 9 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 9 heat exchanger is between 4 – 8 GPM (15.1 – 30.3 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 (P/N 30331) prewired for the Seakeeper 9 Installation and covered under the standard Seakeeper warranty. The pump conforms to the seawater plumbing best practices noted in TB-90947. See Drawing No. 30331, SeaFlo^® Seawater Pump Assembly, and the Seakeeper Options and Accessories Price List for details.
