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.

Product Questions & Answers (2)
Question by: Janet W on Mar 2, 2026, 5:04 PM
Can this pump handle thick fluids, or am I gonna run into trouble?
Answer by: Customer Support on Mar 4, 2026, 4:21 PM
Normal operation is best with fluids in the 85 SUS to 297 SUS range. You might see issues outside that.
Question by: Daryl R on Nov 12, 2025, 4:47 PM
pump says CW rotation on it -- can that be switched if my setup needs to run the other direction?
Answer by: Customer Support on Nov 14, 2025, 4:29 PM
Rotation on these Salami gear pumps can be changed. You reverse the positions of the drive shaft and driven shaft and rotate the front flange, and that flips the direction. Just keep in mind the pump ships standard in clockwise rotation, so any change would need to be done before installation.
