Product Identity

The Dayton 4JPG4 is a three-phase coolant pump rated at 1/25 hp and 115 V AC with a 1.3 amp draw. It targets machine-tool operators who need a compact brass-and-bronze pump for circulating cutting fluid or similar liquids.

Installation Notes

The pump requires a three-phase 115 V supply and fits a 3/8 in NPT intake and discharge. A 3 ft cord limits placement unless extended properly. The 6 in maximum immersion depth must be observed to avoid motor damage.

Suitability

This unit suits maintenance teams running small-capacity coolant systems where 7.1 gpm open flow and 7.8 ft of head are sufficient. It is not for buyers who need higher flow rates, greater head pressure, deeper immersion or single-phase power compatibility.

Questions about this item

How can I verify the pump is operating correctly after installation?

Check that the flow rate reaches up to 7.1 gpm at open discharge and 5.5 gpm at 5 ft of head, with the motor drawing 1.3 amps at 115 V three-phase.

What comes in the box and what must be purchased separately?

The pump unit with 3 ft cord is included; 3/8 in NPT intake and discharge fittings, piping, and coolant fluid are not supplied.

Which capacity should I choose for a system needing 5 ft of head?

At 5 ft of head this 1/25 hp model delivers 5.5 gpm; select it if that flow meets your circulation requirement.
