Description & Features

The Danfoss Series 26 Gear Pump is designed to meet the demands of industrial applications such as tractors machine tools and compactors. This single hydraulic gear pump features a 2-bolt SAE A mounting flange with a 9-tooth SAE A splined shaft and a displacement of 0.58 cu in/rev. It supports a clockwise rotation and has SAE-12 side inlet and SAE-10 side outlet ports.

Rated at 3600 RPM this gear pump ensures optimal performance in the operating temperature range of -20deg;F to 220deg;F. The pressure rating reaches up to 3000 PSI and internal configuration changes easily allow for rotation reversal without additional parts. The standard identification and innovative wear plate further facilitate ease of use and maintenance.

Key features include reduced noise and vibration due to 13-tooth gears improved volumetric efficiency from the bearing lubrication system and a field-reversible pump direction. This configuration makes it suitable for steering circuits sweepers rotary mowers lift trucks and auxiliary work circuits.

Product Questions & Answers (1)

Question by: Brett B on Jan 29, 2026, 6:58 PM
Will this gear pump bolt right up to anything that uses a standard 2-bolt SAE A flange?
Answer by: Customer Support on Jan 31, 2026, 7:46 AM
Yes, this Series 26 gear pump uses the common 2-bolt SAE A mounting flange, so it should fit any application designed for that standard. The 9-tooth SAE A splined shaft also needs to be compatible with your setup.
