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.
