197 Series Small To Medium Displacement Sleeve Bushing Gear Pump

For small to medium displacement needs, the 197 Series is built to fit that role and keep fluid transfer consistent, even when operating conditions change.

Sleeve bushings support the gear shafts using a plain cylindrical bearing surface rather than rolling elements. That design tends to hold up well under steady load conditions and keeps the internal clearances consistent over time. The 197 Series from Permco uses this approach specifically to reduce wear on the rotating components, which helps extend service life and cuts down on how often you're pulling the pump apart for maintenance.
