2.5PB Series Aluminum Gear Pump, 1.97 cu in/rev, 2-Bolt SAE B Mounting Flange, 7/8 13T Splined SAE B Shaft, SAE -16 Side Inlet, SAE -12 Side Outlet, CW Rotation

Description & Features

The 2.5PB Series Aluminum Gear Pump with a displacement of 1.97 cu in/rev is designed for high efficiency and reliable performance in demanding industrial environments. This pump features a 2-Bolt SAE B mounting flange and a 7/8 13T splined SAE B shaft.

It includes SAE -16 side inlet and SAE -12 side outlet ports and operates in a clockwise rotation. The pump operates at a rated flow of 15.3 GPM and a maximum speed of 3000 RPM with a continuous working pressure of 3300 PSI and peak pressures up to 4300 PSI.

Salami gear pumps utilize floating bushings for axial compensation and high volumetric efficiency across the pressure range. DU bearings enhance pressure capability. The pumps are compatible with various shaft flange and port configurations according to European German and American standards.

They are stocked in clockwise rotation but can be reversed by adjusting the drive and driven shaft positions. The pumps are suitable for multiple unit configurations within the same or different series.

Recommended filtration meets ISO 4406 standards and the pumps support a broad range of operating fluid viscosities from 66 SUS to 3635 SUS. Temperature ratings vary with seal types with Buna-N from -4deg;F to 185deg;F and Viton seals up to 230deg;F.

Product Questions & Answers (1)

Question by: Brett H on Feb 2, 2026, 5:02 PM

pump says clockwise rotation only, is that locked in or can it be switched around if my setup runs the other direction?

Answer by: Customer Support on Feb 4, 2026, 8:28 AM

Rotation can actually be changed on these. Reversing the positions of the drive shaft and driven shaft, then rotating the front flange, will get you to counterclockwise. It's not factory-set in a way that's permanent. Just keep in mind the unit ships standard in clockwise, so if you need CCW you'll be making that adjustment yourself on your end.
