  • TEFC motor enclosure protects windings from dust and moisture
  • Capacitor-start single-phase motor runs on 115/208-230 V AC power

Dayton 4UP56 Turbine Pump 2 HP

The Dayton 4UP56 is a single-phase turbine pump rated at 2 hp with a cast-iron housing and totally enclosed fan-cooled motor. It delivers a maximum flow rate of 21 gpm and a shut-off pressure of 110 psi. The unit operates on 115/208-230V AC and accepts 1-inch NPT intake and discharge connections. It suits agricultural, industrial or residential water-transfer tasks that demand moderate pressure and flow.

Upgrade from lower-capacity pumps

This pump replaces smaller centrifugal or jet pumps when higher head or flow is required at 10, 20 or 30 psi. The jump is worth it when the system needs up to 46.2 gpm at 20 psi or 18.5 gpm at 30 psi with a best-efficiency head of 70 ft. It is not for installations that need flows beyond 21 gpm at open discharge or pressures above 110 psi.

Build integration

The capacitor-start motor runs on standard single-phase power without a variable-frequency drive. The cast-iron case withstands up to 300 psi, so existing 1-inch NPT piping can remain in place. The TEFC enclosure protects the windings in dusty or damp environments. Buyers who need a different voltage, three-phase power or larger pipe sizes should look elsewhere.

Questions about this item

What pipe sizes connect to the 1 in intake and 1 in discharge on this turbine pump?

Both ports accept 1 in NPT threaded pipe; use matching male NPT fittings on suction and discharge lines.

Which wiring step is often missed when connecting the 115/208-230 V capacitor-start motor?

Verify the dual-voltage jumper position matches your supply voltage before energising the motor.

When should the mechanical seal be inspected on a cast-iron pump rated for 300 psi case pressure?

Check the seal at each seasonal shutdown or after 2 000 operating hours, whichever comes first.
