The LBLD motor and Simple Pump Solar Kit are discontinued for new orders. Simple Pump stopped selling them on March 31, 2026. If you already own one, nothing changes: parts, service, and warranty continue through the end of 2036. See LBLD owner support.
Setting up automated or solar pumping now? The current path is the Inline Manual-Solar Well Pump System. It pairs a WORKHORSE Narrow Series solar submersible with your Simple Pump using the Inline Dual-Pump Valve Assembly.
Understanding power requirements helps you plan electrical connections or battery systems for your motorized Simple Pump installation.
Motor Voltage Options
The LBLD motor came in two configurations. It is discontinued for new orders, and the specs below are for existing owners:
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, the LBLD motor used the Simple Pump Solar Kit (now discontinued for new orders, still supported for existing owners):
- 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
