Dayton 5UXG2 Booster Pump 1 1/2 hp 208-240/480V 3 Phase 1-1/4 in NPT

SKU CH-2EV0-6V7B8 MPN 5UXG2

A three-phase booster pump delivering up to 52 gpm at 10 psi with a maximum shut-off pressure of 81 psi

  • TypeDrain Components
  • Delivers 52 gpm at 10 psi for strong initial flow
  • Maintains 48 gpm at 20 psi for consistent mid-range output
  • Provides 43 gpm at 30 psi to handle moderate pressure demands
  • Supplies 38 gpm at 40 psi for reliable higher-pressure performance
  • Reaches 81 psi maximum shut-off pressure for system protection

1-1/2 hp Three-Phase Booster Pump

The Dayton 5UXG2 is a cast-iron booster pump rated at 1-1/2 horsepower for three-phase 208 to 240/480 V AC supply. It delivers a maximum shut-off pressure of 81 psi with flow rates from 52 gpm at 10 psi down to 1.9 gpm at 80 psi. The unit has a 1-1/4 inch NPT intake and a 1 inch discharge connection. An open drip-proof motor enclosure protects the windings in dry indoor environments.

Suits Constant-Pressure Water Systems

This pump fits installations that need a steady pressure boost across a wide operating range such as irrigation loops or commercial water supply. The three-phase motor requires a compatible 208 to 240/480 V three-phase service so it is not suited for single-phase residential wiring. Buyers needing a self-priming design or a different voltage should consider other models.

81 psi Shut-Off Pressure Decides Fit

The 81 psi maximum shut-off pressure is the key figure for sizing the pump to the system head requirement. If the application demands pressure beyond this limit the pump will not deliver adequate flow. Verify that the required operating point falls on the published curve between 10 psi and 80 psi before selecting this unit.

Questions about this item

What NPT thread size does the 1-1/4 inch intake require for mounting?

The pump intake uses a 1-1/4 inch NPT thread, so matching NPT fittings or pipe nipples are needed for a secure connection.

How do I wire the 208-240/480V three-phase motor correctly?

Connect the three-phase supply to the motor terminals matching the nameplate voltage of 230/460V AC; verify rotation direction after wiring to avoid reverse flow.

When should I replace the cast-iron housing or seals based on pressure drop?

Monitor flow rates at your operating pressure — for example 48 gpm at 20 psi or 31 gpm at 50 psi — and plan service if output falls significantly below these figures.
