Delivers up to 41 gpm at 105 psi shut-off pressure with a 5 hp three-phase motor in cast iron housing

  • Delivers up to 41.5 gpm at 10 psi for high-volume transfer
  • Maintains 39.8 gpm at 30 psi for consistent pressure performance
  • Handles up to 105 psi shut-off pressure for demanding applications
  • Cast iron housing with 300 psi case rating ensures long-term durability
  • Three-phase 5 hp motor runs on 208-230/460V AC for industrial power compatibility

Three-phase turbine pump for industrial fluid

The Dayton 4UP65 is a 5 hp three-phase turbine pump built with a cast-iron housing and a totally enclosed fan-cooled motor. It is suited for facilities that require continuous duty on 208-230/460 V AC supply. The unit connects to 1-1/4 in intake and 1 in NPT discharge piping.

Thermal management and power profile

The totally enclosed fan-cooled enclosure dissipates motor heat without external ventilation ducts. Operating pressures range from 10 psi to 30 psi with corresponding flows of 41.5, 40.6 and 39.8 gpm, while shut-off pressure reaches 105 psi and maximum case pressure is rated at 300 psi. Best efficiency occurs at 120 ft of head.

Installation requirements and system integration

The pump requires a three-phase electrical service and piping matched to the 1-1/4 in intake and 1 in NPT discharge connections. Its cast-iron construction handles the stated pressure range, freeing the system designer from specifying separate pressure-rated fittings for the pump body. No additional cooling infrastructure is needed beyond ambient airflow around the motor enclosure.

Questions about this item

How do I wire the three-phase motor for 230 V versus 460 V, and which step is often missed?

The motor accepts 208-230/460 V three-phase; the step often missed is moving the internal jumpers to match the supply voltage before energising.

What part will need replacement first under normal operation?

The cast-iron housing and TEFC motor are sealed, so the mechanical seal and bearings are the first wear items to inspect.

At what pressure does flow begin to drop off during continuous running?

Flow stays near 41.5 gpm at 10 psi, 40.6 gpm at 20 psi and 39.8 gpm at 30 psi; the shut-off limit is 105 psi.
