Seaflo Series 51 is a continuous duty 12 volt on demand positive displacement pump.

The 51 Series is a durable continuous-duty automatic water system pump. Screw fittings make installation and service easy. It provides up to 19 litres per minute.

The New Series 51 has a new, sophisticated electronic pressure system automatically adjusting pressure from 17 to 70PSI.

The large 5-chamber diaphragm, provides high volume water flow with reduced pump cycling.

This automatic water system pump is designed for boats and RVs with multiple fixture water systems. 

This model is designed to run on water systems without an accumulator tank.

The innovative and efficient design allows for the quietest operation in its flow-class. The steel mounting with rubber feet absorb vibration and reduce noise. The 51-Series pumps are self-priming, and can run dry without damage. They are capable of self-priming up to 1.8 metres.

This automatic demand water system pump has a built-in pressure switch, which automatically starts and stops and stops the pump when the faucet is opened and closed. They're easy to install and service.
