  • TypeDrain Components
  • Multistage booster cartridge restores pump pressure
  • Includes shaft, coupling, bearings and two O-rings
  • 304 stainless radial bearings and 430 stainless shaft resist corrosion
  • Rated for 140 °F fluid temperature and 300 psi case pressure
  • Compatible with 5NXZ5 and 5NXZ6 pump models

Application fit

The Dayton 5NYD3 is a multistage booster cartridge assembly built for drain and trap systems. It suits technicians who service 5NXZ5 or 5NXZ6 pumps and need a complete replacement cartridge with shaft, coupling, stage components, bearing and two O-rings included.

Compatibility check

Verify that the installed pump is a 5NXZ5 or 5NXZ6 model before ordering. Confirm the system operates within a maximum fluid temperature of 140 F and a maximum case pressure of 300 psi. Ensure the motor enclosure type and single-phase capacitor-start design match the original unit.

Upgrade context

This assembly replaces a worn cartridge in an existing multistage booster pump rather than upgrading to a different pump class. The jump is worth it when the original stages, shaft or seals have degraded and pressure output has fallen below the required level for filtration, cleaning or circulation duties.

Questions about this item

What comes with the 5NYD3 booster cartridge assembly and what must be purchased separately?

The assembly includes the shaft, coupling, stage components, bearing and two O-rings. It is designed for use with the 5NXZ5 and 5NXZ6 multistage booster pumps, which are sold separately.

How do I know whether the 5NYD3 cartridge fits my pump?

The 5NYD3 is listed for use with the 5NXZ5 and 5NXZ6 models only. Check the model plate on your multistage booster pump; if it reads 5NXZ5 or 5NXZ6, this cartridge is the correct replacement.

What temperature and pressure limits apply once the cartridge is installed in the pump?

The pump system is rated for a maximum fluid temperature of 140 F and a maximum case pressure of 300 psi. The motor is designed for a 65 C temperature rise and carries CSA and CUS listings for continuous-duty operation.
