Can we add an engine-drive pump to an existing 240V AC system? Yes. Two pumps give blue-water cruisers redundancy and the flexibility to use whichever power source makes sense at the time.
We can configure, or retrofit, a system with two high-pressure pumps, for example by adding an engine drive to an existing 240V AC system. We often design dual-pump setups for blue-water cruisers who want redundancy. If an exhaust leak soaks your electric motor in a remote anchorage, the second pump keeps the water coming.
Run the engine-drive pump on power the engine is already producing, and arrive at anchor with full tanks without using battery reserves.
Run the AC pump from your generator or a large inverter to top up the tanks without starting the main engine.
The system is manually operated and mechanically regulated, so two pumps don't make it harder. Switch the source water, high pressure and power to the pump you want, then start as normal.
We fit a feed-water switching valve, a high-pressure switching valve, and a 12V dash switch for the engine pump's electromagnetic clutch. On many boats a dual-alternator setup can be combined into one high-output alternator, which frees the second alternator bracket for the engine-drive pump.
For full AC redundancy, we also build systems with twin AC high-pressure pumps feeding a high-output dual-membrane array, for launches and larger power boats.
