Controlling the tire pressure of crop harvesters has numerous advantages, due to different vehicle handling characteristics whether operating on roads or in fields. To address the need, Bosch Rexroth introduced the GFT 8150 TIS (Tire Inflation System), which enables dynamically optimized tire pressure in machines, at Agritechnica 2019 in Hannover, Germany. The new GFT 8150 […]
What are PTO through-drive motors?
By Josh Cosford, Contributing Editor If you’ve spent any reasonable amount of time working on or around mobile machinery, you’re very familiar with PTO-driven machinery, including the hydraulic pump. The PTO shaft exiting the rear of a farm tractor is used to power mechanical implements through a drive shaft, such as bailers or mowers, themselves […]
Closed-circuit variable displacement pump for medium-duty applications
One of the new product highlights at ICUEE this week from the Hydraulic Pump and Power Systems Division of Parker Hannifin Corp., was its new PC3, a variable displacement axial piston pump designed to excel in medium duty applications. The PC3 was launched earlier this year. This high performing, robust compact solution was built to […]
Liebherr’s strategy for electric mobile machines
Among mobile-equipment manufacturers, electrification — the concept of replacing diesel engines and traditional hydraulics with electric drives and batteries — is without a doubt a hot topic. But OEMs should consider both the financial and engineering ramifications before jumping in head first, according to Thomas Schulze, Drive System Application Engineer with Liebherr Components in Biberach, […]
Report: Shift toward mechanization increases demand for hydraulic gear pumps
Worldwide sales of hydraulic gear pumps are likely to surpass 55,000 thousand units by end of 2020, according to a recent research study. Rising demand from a wide-range of industries, including agriculture and construction, continues to work in the favor of hydraulic gear pump manufacturers. A report on Hydraulic Gear Pump Market by Fact.MR claims […]
Simplified hydraulic pumps for the low speed, high torque market
Using mechanical energy produced by a machine’s engine, a hydraulic pump can move hydraulic fluid from the pump’s own reservoir to a connected hydraulic motor, converting the mechanical energy to hydraulic energy. The incoming fluid/energy triggers the hydraulic motor to begin rotation, which can be used to actuate a component outside the system, such as […]
Bucher Hydraulics announces “revolutionary” new pump design
The performance of traditional hydraulic pumps has not kept up with increasingly stringent customer demands and new application requirements, according to officials at Bucher Hydraulics, Klettgau, Germany. They’re tackling such concerns with a new design for piston pumps and motors called the AX series. The AX is not an evolutionary improvement over existing products, said […]
What is the difference between fixed and variable pumps?
For novices in the fluid power industry, lack of understanding between the fixed flow and variable flow pumping concepts is quite common. A hydraulic pump has one mission, and that is to transform incoming mechanical energy at its shaft into hydraulic energy capable of transferring force to actuators somewhere downstream. This transfer of force is […]
Electrification exposes hydraulic-pump shortcomings
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 launches the D1 pump in North America
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 […]
