Series 26 Gear Pumps, Up To 24 GPM @ 1800 RPM, Up To 3000 PSI, Up To 3600 RPM

Description & Features

Application	Rotation may be reversed by reconfiguring internal parts - no extra parts are required. Simply open the pump, switch the drive gear and idler gear, reposition the plug and reassemble. Side Load Limits - contact us for assistance.
Features	13-tooth gears minimize the flow ripple for reduced noise and vibration. Bearing lubrication system uses inlet oil instead of high pressure oil, improving volumetric efficiency. Innovative wear plate permits simple rotation change.
Pressure Limit	Outlet: Varies with displacement (See table below). Inlet: Maximum inlet vacuum at operating condition 6.0 In. Hg.
Rated Speed	Varies with displacement (See table below).
Temperature Range	Minimum Operating -20°F. Maximum Continuous 220°F. Minimum Continuous Oil Viscosity 45 SSU.

Product Questions & Answers (1)

Question by: Lee B on Mar 23, 2026, 2:50 PM

Reckon this'll bolt right up in place of my old pump? It's got SAE-12 and SAE-10 ports like you mention.

Answer by: Customer Support on Mar 25, 2026, 7:09 AM

Fit depends on your specific application, but this gear pump does feature a SAE-12 side inlet and a SAE-10 side outlet, so you're good there. Just be sure to check the dimensions and mounting to be sure.
