3100 Series Small Displacement Roller Bearing Gear Pump

Roller bearing construction is one of the main differences on this 3100 Series pump. That setup is meant to handle shaft side loads more consistently than a bushing style gear pump, which helps in applications where side load is part of the design.

Roller bearing construction handles shaft side loads considerably better than bushing-type pumps, so yeah, that wear pattern you're dealing with should be a lot less of a problem here. Bushing pumps can struggle when there's consistent lateral force on the shaft, and the 3100 Series was built with that exact limitation in mind. For applications where side loading is part of the operating reality, the roller bearing configuration is the more durable choice long term.

This Permco 3100 series gear pump is designed for small displacement hydraulic applications where you need reliable fluid transfer. It's built to hold up under demanding use, thanks to the roller bearing construction.
