Dayton 5NYE0 booster cartridge assembly accessory

Booster cartridge assembly for Dayton pumps

The Dayton 5NYE0 booster cartridge assembly is a replacement module designed for compatible Dayton pump units. It contains the impeller cartridge, coupling, shaft, bearing, stage components and two O-rings required to restore the pump's hydraulic function. The kit is sold new and intended for maintenance or repair of existing installations.

Integrated cartridge with seals and rotating parts

All rotating and sealing elements are supplied in one cartridge, so the installer does not need to source individual O-rings, bearings or couplings separately. This reduces assembly time and ensures the mating surfaces are matched. The product carries a California Proposition 65 notice indicating it contains a chemical known to cause cancer and a chemical known to cause birth defects or other reproductive harm.

Replaces worn cartridge in compatible Dayton models

This assembly replaces a worn or damaged cartridge in pumps that accept the Grainger part number 5NYA9. The upgrade is worth it when the existing impeller, bearings or seals have degraded and a full cartridge swap is faster than piece-by-piece rebuild. It is not for buyers who need a complete pump unit or a different brand fitment.
