1 HP 460 V Submersible Sewage Pump

This Dayton 2JGA7 pump delivers 1 horsepower at 460 V AC three-phase for raw sewage handling. The stainless steel body and impeller resist corrosion in harsh waste environments. An oil-filled motor provides continuous lubrication and cooling during submerged operation. No float switch is included, so automatic control requires a separate device.

Sustained flow at increasing head

Flow rates are rated at 112 gpm at 10 ft of head, 98 gpm at 15 ft and 86 gpm at 20 ft. The three-phase motor draws 2.60 A and maintains output without the torque drop-off seen in single-phase units. Oil-filled construction keeps winding temperatures stable during long pump-down cycles. Buna-N, carbon and ceramic shaft seals withstand abrasive solids without frequent replacement.

Compatibility checks before ordering

Verify that the installation site provides 460 V three-phase power and a starter or contactor rated for 2.60 A. Confirm the discharge piping accepts a 2 inch connection and can handle the rated head pressures. Ensure the basin depth allows full submersion of the pump body for motor cooling. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How much current does the 460 V three-phase motor draw when the pump runs continuously?

The motor draws 2.60 A at rated voltage, so sustained operation stays within that figure.

What discharge piping and electrical supply are required before the pump can operate?

A 2-inch discharge line and a 460 V AC three-phase circuit with overload protection are needed.

Will the 1 HP motor still deliver usable flow if the existing system runs at 20 ft of head?

At 20 ft of head the pump produces 86 gpm, so it continues to move wastewater effectively.
