Description & Features

The Danfoss Power Solutions II LLC (Char-Lynn) Series 26 Gear Pump is a key component for demanding industrial applications like tractors, machine tools, and sweepers. Engineered with 13-tooth gears, this pump ensures minimized flow ripple, resulting in reduced noise and vibration during operation.

This 0.66 cubic inch per revolution pump features a 2-Bolt SAE A mounting flange and a 3/4 St. keyed shaft that is 1-1/4 inches long. It includes a SAE-16 side inlet and a SAE-10 side outlet port, supporting a clockwise rotation. Designed for efficiency, it uses inlet oil for bearing lubrication, improving mechanical and volumetric performance.

With an ability to handle pressures up to 3000 PSI and a speed rating of 3600 RPM, this gear pump offers reliable performance. The innovative wear plate allows for easy rotation changes by switching the drive and idler gears. The robust temperature range of -20deg;F to 220deg;F ensures adaptability in diverse environments.

Product Questions & Answers (3)

Question by: Wade M on May 23, 2025, 1:53 PM
trying to match up ports on my setup. what size are the inlet and outlet on this pump?
Answer by: Customer Support on May 24, 2025, 2:09 PM
Porting on this one is set up with an SAE-16 side inlet and an SAE-10 side outlet, both on the side of the housing.
Question by: Hank P on Sep 8, 2025, 4:50 PM
Hey, I'm trying to figure out if this pump can handle the kind of heat my tractor throws off during the summer. What's the highest temp it can take?
Answer by: Customer Support on Sep 10, 2025, 4:26 PM
This gear pump is rated to handle continuous oil temperatures up to 220°F, so it should hold up even on hot days. Just make sure your system's overall cooling is in good shape.
Question by: Dwayne E on Dec 31, 2025, 5:33 PM
got a little tractor project going. what’s the mounting and shaft size on this pump?
Answer by: Customer Support on Jan 2, 2026, 12:44 PM
For fit-up, it uses a 2-bolt SAE A mounting flange and a 3/4 straight keyed shaft that’s 1-1/4 inches long.
