Description
Lift potable drinking water from deep rock aquifers to pressurized home storage systems. The Flotec 1/2HP 3-Wire 4in Submersible well pump provides reliable residential water supply. A 0.5-horsepower 230-volt motor couples to an abrasion-resistant multi-stage pump wet end. The 3-wire system requires a separate above-ground control box containing start capacitors.
Heavy-gauge 304 stainless steel encases the motor and multi-stage pump assembly. Precision-molded thermoplastic impellers float inside individual stages to prevent sand locking during startups. The cast-iron discharge head incorporates a built-in check valve to stop water hammer shocks. A splined stainless steel shaft transfers motor rotation without torsional slippage. Non-toxic dielectric fluid cools the motor internals.
Deep Well Submersible System Details
Plumbing contractors configure deep well water feeds with above-ground capacitor servicing access. The 3-wire motor allows component troubleshooting without pulling drop pipes out of wells.
- Industrial 0.5-horsepower motor operates on 230-volt power via an external control box
- Multi-stage pump wet end delivers 10 GPM from depths down to 150 feet
- External control box simplifies capacitor replacement without pulling downhole drop pipes
- Stainless steel pump casing resists chemical erosion from acidic groundwater sources
- Floating thermoplastic impellers pass fine sand grains without mechanical binding issues
- Internal check valve blocks backflow down the well casing during motor shutdowns
- Threaded 1.25-inch NPT discharge connects straight to standard well drop pipe
Hydrodynamic Bench Telemetry Data
Bench testing demonstrates the motor draws 5.2 Amps across 230-volt lines under a 120-foot dynamic head. Flow meters record 9.6 GPM water delivery into a 30/50 PSI pressure tank. The motor stator runs cool at 122°F in moving well water. Starting current draws 18 Amps for 0.4 seconds before settling to continuous running load.
Jobsite Operation Mechanical Realities
You suspend this pump in 4-inch well casings with schedule 80 PVC or poly drop pipe. The external control box mounts inside dry basements for fast electrical testing. Do not operate this unit without a matched Flotec control box. Mismatched start capacitors cause low motor torque that burns out the auxiliary windings.
- Mount the external control box in a moisture-free indoor service location
- Measure well casing recovery rates to ensure continuous water submergence over the pump
- Install torque arrestors above the pump discharge to stop pipe twisting during start
Factory Warranty Complete Manifest
Flotec provides a 3-Year limited warranty covering pump and motor components. The shipping box contains the 0.5-horsepower 3-wire pump, integrated check valve, cable splice kit, and detailed wiring diagrams.
