Increasing reliability and reducing wear under high pressure

While other hydraulic motors include a case drain port as a third zone, the Delta motor architecture makes the third zone unnecessary. With fewer components and potential failure points, the Delta’s two-zone design improves reliability at the outset and offers more trouble-free operation throughout its life. Introducing Eaton’s Delta motor — a low-speed, high-torque motor that sets an entirely new standard for performance and durability. Reliability by Design Eaton’s tradition of innovative solutions and trustworthy performance under the toughest conditions continues with the Delta motor. Designed...

Increased drive life Common applications for the Delta motor: Turf care – traction drives Sweepers – brush drives Attachments – auger drives Utility – propel Delta motor accelerated life tests Due to their design, drive wear on most two-zone motors creates contaminants that travel back to the pump. And because pumps are highly sensitive, they fail prematurely due to excessive contamination and require costly replacement. The Delta motor’s robust, proprietary drive was designed with one goal in mind: enhance reliability to eliminate failure. This low-speed, high-torque motor sets the new standard...

Testing included the following conditions: • DTE-24 @ 67°C (~12 cSt) • CCW Direction - 95% of the time* • 1000 psig (69 bar) on shaft seal @ 200 rpm • CW Direction - 5% of the time • 2000 psig (138 bar) on shaft seal @ 200 rpm Note: *Since backing up (reverse direction) challenges motor operation, thorough testing was performed in the CCW direction.
