The pump uses a DC motor (typically 12V, 24V, or 48V).
When powered, the motor drives an impeller or diaphragm mechanism.
This creates suction at the inlet and pushes water out at higher pressure.
Since it runs on DC, it’s commonly powered by:
Batteries
Solar panels (very popular in off-grid setups)
Vehicle electrical systems
Use spinning impellers
Good for continuous water flow
Diaphragm DC pumps
Use a flexible membrane
Self-priming and good for intermittent use
1. Voltage
Common options: 12V DC, 24V DC, sometimes 36V/48V
Lower voltage (12V): small systems (RVs, caravans)
Higher voltage (24V+): more powerful, efficient for larger setups
2. Power Consumption
Measured in watts (W)
Typical range: 60W – 300W+
Higher wattage = stronger pumping capacity
3. Flow Rate (Discharge Capacity)
Measured in:
Liters per minute
