Cartridge Assembly for Dayton Pumps

This replacement cartridge fits Dayton pump models 5NYA5 and 5NYA6. It restores the pump’s internal flow path by supplying a fresh impeller cartridge with all required stage components. Maintenance technicians use it to return a worn unit to service without replacing the entire pump body.

Pre-Assembled Core with Seals and Bearings

The cartridge arrives complete with two O-rings, a bearing, coupling and shaft already fitted. This reduces the number of loose parts to handle during installation and helps maintain alignment between rotating and stationary elements. The sealed assembly limits contamination risk when the pump is opened for service.

Direct Swap for Worn Impeller Cartridges

It replaces a damaged or eroded cartridge inside compatible Dayton booster pumps. The upgrade is worthwhile when the existing cartridge shows reduced pressure output, unusual noise or seal leakage. Pumps with cracked housings or motor faults will not benefit from this part alone.

Highlights

  • Dayton impeller cartridge restores pump performance
  • Includes two O-rings for reliable sealing

Questions about this item

What Grainger part numbers does the 5NYD8 cartridge assembly fit?

The 5NYD8 booster cartridge assembly is compatible with Grainger part numbers 5NYA5 and 5NYA6, covering the specified Dayton pump models.

What hardware is included in the box for installation?

The assembly ships with two O-rings, a bearing, coupling, shaft, and stage components so you have every seal and rotating part needed for the rebuild.

How do you install the cartridge, and which step is most often missed?

Remove the old cartridge, lubricate and seat both supplied O-rings, insert the new assembly with the bearing and coupling aligned, then torque the housing — skipping the second O-ring is the common error.
