Pentair 2nfl51-12-p4-02 Submersible Well Pump 0.5 Hp

Product Description

The PENTAIR 2nfl51-12-p4-02 is a 1/2 HP submersible well pump rated for 12 GPM flow at 115 volts. Designed for residential and light commercial groundwater extraction, this pump installs below the water table inside a drilled well casing and delivers pressurized water to the distribution system above. The steel construction resists the mechanical stresses common in deep-well environments. At 29 pounds, the unit is sized for standard 4-inch or compatible well casings and is serviced by licensed well pump contractors or plumbing professionals.

This submersible pump is suited for residential potable water supply systems where a reliable, electrically driven pump is required below grade. Typical applications include private well water supply for homes, cabins, and light agricultural use. The 115-volt single-phase power requirement makes it compatible with standard residential electrical service without the need for a dedicated high-voltage circuit. Installation typically pairs this pump with a pressure tank and pressure switch to maintain system pressure.

Key Features

• 1/2 HP motor delivers 12 GPM flow capacity for residential water supply demands
• 115-volt single-phase operation compatible with standard residential electrical service
• Steel construction for durability in submerged well environments
• Submersible design keeps the motor cool through continuous water contact
• 29-pound unit weight sized for practical handling and installation in well casings

Compatibility

Designed as an OEM-style replacement or direct-install submersible well pump for residential drilled well systems requiring 1/2 HP, 12 GPM performance at 115 volts.

Installation Notes

Installation must be performed by a licensed well pump contractor or plumber in accordance with local codes and NFPA 70 (NEC) requirements for submersible pump wiring. Disconnect and lock out all electrical power before lowering or retrieving the pump assembly. Safety rope or a rated drop cable should be used to support the pump in the well casing — never support the unit by the power cable alone. Confirm well casing diameter and static water level before sizing the drop pipe and wiring run.
