Selecting a Replacement Pump for Pond-Fed Drip Irrigation

System Requirements

• Source: Pond, 23 ft vertical lift, 85 ft horizontal run to barn.
• From barn: 60 ft to drip zone, last emitter 150 ft from regulator.
• Demand: 200 GPH (3.3 GPM) at 10 PSI at emitters.
• Old F&W bullet pump with large tank—data plate gone.

Pump Sizing

Total dynamic head ≈ 23 ft lift + friction (minimal at 3.3 GPM) + 10 PSI (23 ft) ≈ 50 ft head. Flow: 3.3 GPM. A 1/2 HP self-priming shallow well/jet pump is sufficient. Reuse existing pressure tank if functional.

Pump Recommendation

Simer (Pentair group) offers affordable, widely available pump systems. Their "plug-and-play" units include pump, tank, and switch. See: Simer Pump Catalog (PDF)

Local Availability Matters

Pump brands vary by region. If you have local dealer names (Goulds, Sta-Rite, Myers, Red Jacket, etc.), I can specify exact models. Otherwise, Simer is a safe online choice.

Key Installation Notes

• Suction line must be airtight—no leaks, no "almost good enough."
• Install foot valve with screen at pond intake.
• Prime pump before first start.
