Description
Deliver pressurized potable water from deep underground wells to residential storage tanks. The Red Lion 3/4HP 12GPM 230V Deep well submersible pump provides reliable water volume from deep rock casings. A 0.75-horsepower continuous-duty motor turns an abrasion-resistant multi-stage impeller stack. The 12-GPM flow rate requires deep well recovery rates to prevent running casings dry.
Corrosion-proof 304 stainless steel forms the outer shell, motor casing, and splined drive shaft. Glass-filled thermoplastic impellers float inside individual stages to prevent sand locking during startup. A built-in stainless steel check valve prevents water column backflow down the well drop pipe. Hermetically sealed motor windings run in dielectric fluid for maximum thermal dissipation. Cast stainless steel discharge heads endure stress.
Deep Well Submersible System Details
Plumbing contractors install deep aquifer water lift systems with dependable downhole hardware. The multi-stage impeller stack maintains high line pressure across multi-story residential plumbing networks.
- Continuous-duty 0.75-horsepower motor operates on standard 230-volt single-phase residential power
- Multi-stage floating impeller stack delivers 12 GPM from depths down to 250 feet
- Corrosion-proof 304 stainless steel shell resists harsh mineral scale buildup
- Built-in check valve stops water hammer damage on external plumbing pipes
- Glass-filled thermoplastic stages resist abrasion wear from underground silica sand
- Integrated suction screen blocks gravel particles larger than 0.08-inch diameter
- Standard 1.25-inch NPT discharge connects straight to schedule 80 drop pipe
Hydrodynamic Dyno Load Telemetry
Dynamometer testing confirms the electric motor draws 6.6 Amps on 230-volt circuits under a 180-foot total dynamic head. Water discharge stabilizes at 12.2 GPM into pressurized bladder tanks. Motor winding temperatures stabilize at 126°F within flowing 55°F well water. The internal thrust bearing endures 650 pounds of downthrust during continuous deep-well pumping runs.
Worksite Performance Practical Notes
You lower this pump down 4-inch well casings using a dedicated safety torque cable. The smooth stainless steel shell slides past casing joints without snagging. Do not run this pump inside dry well casings without water cover. Operating the motor without fluid flow causes rapid thermal expansion that destroys the stator windings.
- Install a dedicated check valve on the drop pipe every 100 vertical feet
- Test motor electrical insulation resistance with a megohmmeter before dropping well pipes
- Secure electrical drop wires to the pipe with waterproof tape every 10 feet
Commercial Warranty Specifications Manifest
Red Lion covers this deep well pump with a 3-Year limited manufacturer warranty. The factory package contains the 0.75-horsepower submersible pump, integrated check valve, waterproof cable splice kit, and complete plumbing installation manual.
