SEAFLO 42-SERIES PUMP DP204005542
Premium 24V High-Flow Water Pressure Solution
The SEAFLO 42-Series is a heavy-duty, 4-chamber diaphragm pump engineered to provide consistent water pressure for multiple fixtures on your boat or RV. This 24V model delivers an impressive 4.0 gallons per minute (15.1 LPM), making it ideal for systems requiring high-volume throughput. Equipped with internal bypass technology, this pump significantly reduces rapid on/off cycling, leading to smoother flow and a longer lifespan for the motor and pressure switch.
Key Features
- ✔ Internal Bypass: Reduces rapid cycling for quiet operation
- ✔ Self-Priming: Suction lift up to 6 feet (1.8m)
- ✔ Run Dry Safe: Can run without water without damaging components
- ✔ Vibration Control: Rubber mounting base for noise reduction
- ✔ Protection: Built-in thermal overload protection

Questions & Answers
Is this pump compatible with saltwater?
Yes. The EPDM valves and Santoprene diaphragm are highly resistant to chemicals and can handle saltwater applications such as deck washdowns safely.
Do I need an accumulator tank with this model?
While the internal bypass reduces cycling significantly, an accumulator tank is always recommended for the smoothest flow and to reduce wear on the pressure switch during very low flow usage.
Can the pressure switch be adjusted?
Yes, the 42-Series features an adjustable pressure switch, though the factory setting is optimized for the 55 PSI shut-off limit.
Note: Please verify your original voltage requirements (24V) before purchasing to ensure system compatibility. For further information, visit 4boats.co.uk.
