Heightened concerns over climate change and global warming are key reasons for the growing interest in zero-emission vehicles. Battery-electric mobile machines, while still mainly in the prototype stage, may require hydraulic-pumps and variable-speed drives to evolve to suit future applications. Hydraulic pumps are high-performance components. However, according to engineers at Bucher Hydraulics, Klettgau, Germany, they […]

Danfoss Power Solutions introduced the D1 High Power Open Circuit Axial Piston Pump to the North American market. The D1 pump is a high pressure, high flow variable displacement axial piston pump, developed specifically for open circuit systems in the most extreme application environments. Its design makes it a suitable solution for mining, heavy duty […]
Building a world-class hydraulic pump
Understanding what can go wrong ensures that hydraulic pumps get built right. Every OEM says it wants quality, but the reality is that machine builders can choose from countless hydraulic components that vary widely in performance and price—from cheap, “throw-away” parts to high-quality and, more-expensive, products that are built to last. How does an engineer […]
How do you calculate HPU pressure and flow requirements?
By Josh Cosford, Contributing Editor Before you select a pump for your HPU, you must calculate your pressure and flow requirements. To calculate flow required by your hydraulic pump, you must know the size and velocity of the actuators it will power. It is important to calculate the maximum flow required during simultaneous actuator operation, […]
What hydraulic pump type is best for my HPU design?
By Josh Cosford, Contributing Editor The type of pump you choose for your power unit affects the nature of the HPU build. Pump choice boils down to cost, complexity and performance. There are three major types of pumps: the gear pump, the vane pump and the piston pump. There are other, less common pumps, but […]
Hydraulic pumping system
New L7-000S120 pump features pressures to 12,800 with 100-psi air drive, flows of 2.9 gpm at no pressure and 1.1 gpm at 8,000 psi with 100-psi air drive. All wetted parts are stainless steel, and pump is compatible with most fluids. Air operated system needs no electricity. Can be used in numerous industrial applications, including […]
NFPE control option for MP1 pumps
Danfoss Power Solutions introduces a new Non-Feedback Proportional Electric (NFPE) control option for its MP1 closed circuit axial piston pumps. The MP1 already provides modular configuration for manufacturers seeking a reliable pump, and the NFPE control expands the MP1 control portfolio for further customization. The NFPE control will be available in the first quarter of […]
