Understanding power requirements helps you plan electrical connections or battery systems for your motorized Simple Pump installation.
Motor Voltage Options
Simple Pump offers two motor configurations:
24V DC Motor (LBLD24)
- Nominal voltage: 24V DC
- Power draw: 5-10 amps depending on lift depth
- Maximum lift: 225 feet (with 100CA cylinder)
- Power source: Two 12V batteries in series, or 24V battery bank
12V DC Motor (LBLD12)
- Nominal voltage: 12V DC
- Power draw: 10-15 amps depending on lift depth
- Maximum lift: 200 feet (with 100CA cylinder)
- Power source: Single 12V deep-cycle battery
Power Source Options
Battery Systems
Both motor configurations require battery power:
For 24V Systems:
- Two 12V deep-cycle batteries in series
- Or dedicated 24V battery bank
- Provides consistent power delivery
For 12V Systems:
- Single 12V deep-cycle battery
- Common with vehicle or RV systems
- Widely available batteries
Solar with Battery Backup
For solar-powered installations, Simple Pump offers the Solar Powered Well Pump Kit:
- 740 watts of solar (two 370W panels)
- MPPT charge controller included
- Battery system required (customer-provided)
- 12V or 24V motor options
Direct solar connection without batteries is not a supported configuration. All motorized Simple Pump systems require battery power for proper operation.
Generator or Grid Power
For AC power sources:
- Use a quality battery charger to maintain batteries
- Batteries buffer power to the motor
- Provides clean, consistent DC power
Factors Affecting Power Draw
Pumping Depth
Deeper wells require more power:
- Shallow wells: Lower current draw
- Medium depth: Moderate current
- Deep wells: Maximum power required
Cylinder Size
Larger cylinders move more water but need more power:
| Cylinder | 24V Motor Max | 12V Motor Max |
|---|---|---|
| 100CA | 225 ft | 200 ft |
| 125CA | 150 ft | 125 ft |
| 200CA | 60 ft | 50 ft |
Pressure Tank Operation
Pumping into pressure tanks increases load:
- Add pressure equivalent to total dynamic head
- 1 PSI ≈ 2.31 feet of head
- 45 PSI tank adds ~104 feet equivalent
Battery Sizing Guidelines
For reliable operation, size batteries based on:
- Daily pumping requirements
- Available charging capacity (solar/grid)
- Desired days of autonomy
General guidance:
- Use deep-cycle batteries (not starting batteries)
- Avoid discharging below 50%
- Size solar/charging to fully replenish daily use
Important Considerations
Wire Sizing
- Use adequate gauge for current and distance
- Minimize voltage drop over cable runs
- Follow electrical codes for your installation
Motor Protection
- Include appropriate fuse or circuit breaker
- Protect from voltage spikes
- Use surge protection with solar systems
