Berkeley S19310 Shaft Sleeve — Slip-Fit (19310)
The Berkeley S19310 shaft sleeve is a stainless steel slip-fit sleeve for 1-1/4″ Berkeley Type B pumps, equivalent to Berkeley part numbers S19310 and S19310L. It carries the wear at the seal face so the pump shaft doesn’t — a $30 sleeve replaces what would otherwise be a shaft replacement or a scrapped rotating assembly.
A chamfered lead-in eases installation without rolling the seal elastomer, and a machined groove in the outer diameter seats the S11207 external retaining ring for positive axial location.

A worn sleeve is the most common reason a new mechanical seal fails early. If the old sleeve has a visible track where the seal faces rode, replace it — new faces running on a grooved sleeve will weep within hours.
Ordering tip: Verify ID, OD, and length against your pump’s parts list or nameplate before ordering. Contact us with your Berkeley model number and we’ll confirm the fit.
The sleeve is one of three parts in this joint.
Berkeley’s Type B service group is the seal, the sleeve, the retaining ring, and the volute gasket. The ring ships with this sleeve — here are the other two.
• PS-185 Mechanical Seal — replaces Berkeley S32014. 1-1/4″ shaft, 1.875″ × 0.437″ seat, Type N-11 (Type C/21). Nitrile, Viton, and SiC/SiC options.
Installing the seal? A drop of P-80 rubber lubricant lets the elastomer slide over the chamfer instead of rolling or nicking.
