Purpose and fit

The Flint & Walling 135627 booster cartridge is a replacement impeller assembly for PB-series booster pumps. It restores hydraulic performance when the original cartridge wears or corrodes.

Deciding specification

The cartridge contains 11 stages and ships with two O-rings, a coupling, a discharge bearing, a shaft and the stage components. It matches manufacturer models PB2711A201 and PB2711A203 and Grainger part numbers 22W719, 22W720, 2PC34 and 2PC35.

Build integration

The cartridge installs directly into compatible PB-series booster housings without additional machining. It does not fit pumps outside the listed model numbers, so buyers with different pump series must source the correct cartridge for their unit.

Questions about this item

What does the 11-stage count mean for pressure output once the cartridge is installed in a PB-series booster pump?

Eleven stages multiply the pressure rise across each impeller, so the cartridge delivers the higher head that PB2711A201 and PB2711A203 pumps are rated for.

Which pump models and Grainger part numbers does this cartridge fit, and what does that compatibility cap in practice?

It fits PB2711A201 and PB2711A203 pumps and replaces Grainger 22W719, 22W720, 2PC34 and 2PC35, limiting use to those exact booster-pump configurations.

What physical parts come in the box for mounting the cartridge into the pump housing?

The package includes two O-rings, a coupling, a discharge bearing, a shaft and all stage components needed to seat the cartridge inside the cast-iron housing.
