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.
Yes, Simple Pump can efficiently fill residential pressure tanks. The pump is engineered to develop up to 45 psi pressure, suitable for most home pressure tank systems.
How Pressure Generation Works
Simple Pump generates pressure through:
- Precision-machined components - Tight tolerances minimize leakage
- Quality seals - 90 durometer urethane/buna seals
- Leverage advantage - Lever arm multiplies your effort
- Positive displacement - Each stroke moves a fixed volume
Pressure Capability by Cylinder
| Cylinder | Pressure Capability | Notes |
|---|---|---|
| 100CA | Up to 45 psi | Best for deeper wells |
| 125CA | Up to 45 psi | Moderate depth |
| 200CA | Up to 45 psi | Shallow wells, higher volume |
What This Means for Your Home
A standard residential pressure tank typically operates at:
- 30-50 psi range - Common household setting
- Cut-in at 30 psi - Pump starts
- Cut-off at 50 psi - Pump stops
Simple Pump at 45 psi can:
- Fill your pressure tank to normal operating pressure
- Maintain household water pressure
- Supply fixtures and appliances
Factors Affecting Pressure
Your actual pressure capability depends on:
- Static water level - Deeper water = more effort needed
- Total lift - Depth to water plus pressure head
- Cylinder model - Smaller cylinders = less effort, more strokes
- Physical effort - Your pumping strength
Installation for Pressure Tank Use
To pump into your pressure tank:
- Check valve required - Prevents backflow
- Proper plumbing connection - Tie into pressure system
- Gauge for monitoring - Watch tank pressure
Realistic Expectations
With hand pumping:
- Filling takes time - Expect 15-30 minutes for a full tank
- Good exercise - Pumping against pressure is a workout
- Effective backup - Provides water when power is out
Automated Pressure Tank Filling
For regular pressure tank use, an automated setup helps. The LBLD motor that once did this is no longer sold for new orders. For a new automated or solar setup, see the Inline Manual-Solar Well Pump System. Existing LBLD owners can keep using their motor for pressure tank filling.
