L2 Series Gear Pump, 2.05 cu in/rev, 2-Bolt SAE B Mounting Flange, 13 Tooth SAE B Splined Shaft, SAE-20 Side Inlet, SAE-12 Side Outlet Ports, CW Rotation.

Description & Features

Designed for demanding fixed-displacement hydraulic circuits, the L2 Series Gear Pump delivers 2.05 cu in/rev displacement at a rated speed of 2750 RPM, with a pressure rating of 3600 PSI and a rated flow of 15.9 GPM. The 2-bolt SAE B mounting flange and 13-tooth SAE B splined shaft provide straightforward integration into standard hydraulic drive configurations.

Port configuration consists of an SAE-20 side inlet and SAE-12 side outlet, with clockwise shaft rotation. Operating temperature range spans from -20°F minimum to 225°F continuous maximum. The pump is field-reversible for direction, and its single-configuration design supports a wide range of industrial sectors including agricultural equipment, material handling, civil engineering, metal forming, and specialty construction.

Manufactured by Eaton Char-Lynn under the Danfoss Power Solutions brand, this unit offers reduced noise and vibration alongside solid volumetric and mechanical efficiency for mobile and stationary hydraulic applications.

Question by: Judy K on Jan 8, 2026, 3:58 PM
What kind of stuff is this pump good for?
Answer by: Customer Support on Jan 10, 2026, 6:45 AM
This L2 series gear pump works in agricultural equipment, civil engineering, material handling, and specialty construction, among other applications.
Question by: Terry C on Jun 8, 2025, 6:07 AM
got a 2-bolt SAE B mount and a 13-tooth SAE B spline on my setup. is this pump the right match, and which way does it spin?
Answer by: Customer Support on Jun 9, 2025, 4:42 PM
It matches a 2-Bolt SAE B mounting flange and a 13 Tooth SAE B splined shaft. Rotation on this model is CW.
Question by: Chad H on May 9, 2025, 3:07 PM
Got a machine running a 2-bolt SAE B setup with a 13-tooth splined shaft, this pump gonna drop right in without any adapter nonsense?
Answer by: Customer Support on May 11, 2025, 6:00 AM
Straight bolt-up on a standard 2-bolt SAE B flange, and the 13-tooth SAE B splined shaft matches that mount pattern exactly. Port side gives you an SAE-20 inlet and SAE-12 outlet, both side-ported. Long as your existing hydraulic connections lines up to those port sizes, you're not looking at any adapter work on the mechanical end.
