PG331 Series Cast Iron Gear Pump, 1.74 cu in/rev, 2/4-Bolt SAE B Mounting Flange, 13T Splined x 1.61 long SAE B Shaft, SAE -16 Side Inlet SAE -12 Side Outlet, CW Rotation

Designed for demanding hydraulic applications, the PG331 Series Cast Iron Gear Pump, 1.74 cu in/rev, 2/4-Bolt SAE B Mounting Flange, 13T Splined x 1.61 long SAE B Shaft, SAE -16 Side Inlet SAE -12 Side Outlet, CW Rotation is a single gear pump from Salami S.P.A. built around a cast iron housing and floating bushing axial compensation for consistent volumetric efficiency across the working pressure range.

Rated at 4,000 PSI continuous with peak capability up to 4,350 PSI, this pump delivers 13.4 GPM at a rated speed of 2,700 RPM. The 2/4-bolt SAE B mounting flange and 13-tooth splined SAE B shaft support straightforward integration into standard mobile and industrial hydraulic circuits. Standard Buna-N seals cover operating temperatures from -4°F to 185°F, with Viton seal options extending the upper limit to 230°F. Clockwise rotation is standard; rotation can be reversed by repositioning the drive and driven shafts and rotating the front flange.

DU bearings contribute to high-pressure capability, and the pump is compatible with fluid viscosities ranging from 66 SUS to 3,635 SUS. Recommended filtration is ISO 4406 class 20/19/16 below 2,900 PSI and 19/18/15 above.
