620 Series Mobile Piston Pumps
The Danfoss X20 portfolio of open-circuit piston pumps is built to maximize machine performance and productivity. With sophisticated controls that enhance system efficiency and a compact design that delivers incredible power, the X20 portfolio empowers mobile machine operators to do more work in less time using less fuel.
Danfoss 620 Series is currently available in 74cc (4.54 in3/r) and 98cc (5.98 in3/r) displacements. It is rated at 310 bar and is capable of generating over 100 kW (134 hp), making it the ideal pump for an array of different mobile and stationary applications. The 620 design also incorporates many new advances in product reliability. Once equipment is in the field, failures can prove to be extremely expensive by causing costly downtime. The 620 blends Danfoss long tradition in providing quality pumps with the latest design and technology methods to ensure long lasting product reliability. The result is a very simple design with 25% fewer parts and a B-10 bearing life rated to over 80,000 hours at 2,000 psi far exceeding the requirements for most applications.
