Open Circuit Pumps
Series 45
For more than 40 years, Danfoss has been developing state-of-the-art components and systems for mobile machinery used in off-highway operations around the world. We have become a preferred supplier by offering the best of what really matters: The hardware inside your vehicle application.
Series 45 pumps are a high efficiency alternative to traditional open circuit pumps. Each frame size is uniquely designed to optimize performance, size, and cost, while matching the demanding requirements of the mobile equipment market.
Series 45 pumps are designed to fit the needs of open circuit systems capable of speeds up to 3600 rpm, maximum pressures up to 400 bar, continuous pressures up to 310 bar [4500 psi]. Series 45 pumps offer a wide variety of control options such as Electronic Torque Limiting (ETL).
Series 45 pumps are PLUS+1® compliant. With robust designs and proven reliability in the test lab and the field, Series 45 pumps set the standard for market quality. Danfoss pumps are supported by a global network of authorized service centers.
