The Seakeeper 3 is shipped with the cooling circuit (Figure 22) filled and ready for use. To cool the Closed-Loop glycol circuit on the unit, it requires a connection to a raw water pump, referred to as the seawater pump. When the on-demand cooling system requires cooling, the required seawater flow through the Seakeeper 3 heat exchanger is between 2 and 6 GPM (7.6 and 22.7 LPM). Prior to operation, confirmation of the glycol level is recommended.

Seakeeper offers a compatible self-priming DC Seawater Pump (P/N 30331) prewired for
installation on the Seakeeper 3 and covered under the standard Seakeeper warranty. See Drawing No. 30331,
Seakeeper DC Seawater Pump Assembly for details and the Seakeeper Options and Accessories Price List for pricing information.
