Dayton 4UP53 Turbine Pump 3/4 HP 115/208-230V AC

SKU CH-0MKJ-B4D32 MPN 4UP53

A turbine pump delivers 3/4 hp at 115/208-230V AC with a maximum shut-off pressure of 145 psi and flow rates of 8.9 gpm at 10 psi, 8.6 gpm at 20 psi and 8.4 gpm at 30 psi

  • TypeDrain Components
  • Delivers up to 8.9 gpm at 10 psi for strong drainage performance
  • Maintains 8.4 gpm at 30 psi showing consistent flow under pressure
  • 3/4 hp capacitor-start motor provides reliable single-phase power
  • Cast iron housing withstands 300 psi maximum case pressure for durability
  • Dual-voltage 115/208-230V AC design suits varied electrical supplies

3/4 HP Turbine Pump

The Dayton 4UP53 is a single-phase turbine pump built for drainage and trap applications. Its cast-iron housing and open dripproof motor enclosure suit installations where a 1-inch NPT intake and discharge are required. A capacitor-start motor delivers 3/4 horsepower across 115, 208 or 230 V AC supply.

Voltage and pressure limits

The pump operates on 115/208-230 V AC single-phase power. Case pressure is rated to a maximum of 300 psi while shut-off pressure reaches 145 psi. Flow rates are documented at 10, 20 and 30 psi reference points, so performance outside those pressures is not characterised.

Flow capacity and headroom

At 10 psi the pump delivers 8.9 gpm, falling to 8.6 gpm at 20 psi and 8.4 gpm at 30 psi. Best efficiency occurs at a head of 78 ft. The unit is not suited for systems requiring higher flow rates or pressures beyond the stated maximums.

Questions about this item

Which voltage option should I pick for my 115 V supply?

The motor is rated for 115 V on the low-voltage connection and 208–230 V on the high-voltage connection; wire it to match the circuit you have.

What does the 8.9 gpm maximum flow rate mean once the pump is installed?

At 10 psi and 20 psi the pump still delivers 8.9 gpm and 8.6 gpm, so you get near-peak output across typical low-pressure drain runs.

How does the 1 in NPT discharge limit the pipework I can use?

The discharge is 1 in NPT, so you must connect 1 in NPT-threaded pipe or fittings; larger or smaller sizes need adapters.
