220 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.
The 220 series is currently available in 18cc (1.09 cu. inch) and 28cc (1.71 cu. inch) displacement. It is rated for 280 bar and up to 3,600 rpm and is capable of generating up to 52.6 horsepower (39.2kW), making it the ideal pump for an array of different mobile and stationary applications. The combination of high load capacity bearings and a stiff drive shaft help provide a pump B10 bearing life of up to 5,850 hours at rated mobile conditions, reducing operating costs and extending operating life.
