Flint & Walling Booster Cartridge

The Flint & Walling 136685 is a stainless-steel impeller cartridge built for the PB series booster pumps. It replaces the complete stage assembly in compatible models and includes two O-rings, a coupling, a discharge bearing, a shaft and all stage components. Installers servicing Flint & Walling PB1014S101 or PB1014S103 pumps use this cartridge to restore original hydraulic performance without replacing the entire pump body.

Fourteen-stage stainless construction

The cartridge contains 14 precision-moulded stages that generate the pressure rise required by PB-series booster applications. It fits the Grainger part numbers 22W730, 22W731, 2PC45 and 2PC46, so maintenance teams can standardise on one spare for several pump variants. The design does not suit pumps outside the PB series or units that call for a different stage count, so verify the model tag before ordering.

Sealed assembly for quiet operation

Because the stages, shaft and bearings are pre-aligned in a single cartridge, vibration and hydraulic noise stay low during normal duty cycles. The included O-rings seal the stage stack against internal leakage, keeping efficiency stable over time. No separate bearing lubrication or shaft alignment is needed after installation, reducing service time on the job site.
