Parker Hydraulics News and Insights
Six things you never knew about Heavy-Duty Hydrostatic Piston Pumps and Motors
Parker Gold Cup heavy-duty pumps and motors have long been respected in the industry for technical excellence in hydrostatic transmission applications in marine, drilling, and shredding applications, among others.
You are also probably aware that the heavy-duty Gold Cup series of pumps and motors represent Parker’s and Denison’s combined expertise in hydrostatic transmission applications.
But you may not be aware of Gold Cup’s, heavy-duty hydrostatic piston pump and motor value-added features and benefits…
10 Frequently asked Questions you should know about Power Take-Offs
A Power Take-Off, or PTO, gives a truck versatility beyond its usual function of providing transportation for materials. It directs power to the auxiliary equipment to perform work at the site and/or enroute.
A PTO can eliminate the need for a second, or auxiliary, engine to power the equipment. Efficiency is gained through a PTO being applied to any form of vehicle transportation application including dump trucks, garbage trucks, snow trucks and many more.
Three reasons to choose the Parker V16 Variable Displacement Hydraulic Motor for your Mobile Application
Parker’s Series V16 is the next generation of variable displacement, bent-axis motors. It further develops their well-known V12 and V14 hydraulic motor series.
It is designed for both open and closed circuit transmissions focusing on high-performance machines and demanding mobile applications. Rigorous product testing and continuous product development help to ensure our hydraulic motors operate at optimum efficiency and outperform in the most demanding environments.
Advantages of Helical Hydraulic Actuators in Heavy-Duty Applications
Hydraulic actuators cause engineered equipment to move, slide, rotate and lift by converting energy from pressurized fluid and hydraulic power units.
Depending on the type of machinery involved and the desired movement needed, there are a variety of linear and rotary actuators available to best match the needs of the designer.
Rayco Stump Cutter uses Parker Pump and Motor Combination
Following the introduction of more stringent Tier IV diesel engine emissions regulations, Rayco, an environmental equipment designer for the tree care and landscape industries, developed a more efficient, powerful and compact stump cutter, the RG165T-R, centered around a powerful 165 HP gasoline engine.
Check Valves are the Unsung Heroes of Fluid Power
Check valves are unseen and undervalued – despite the fact that these valves are found in just about every mobile and industrial hydraulic system on the planet. Simply put, if there’s a pump, most likely you will find a check valve. Check valves keep the fluids flowing in the desired direction to prevent damaging flow or pressure in the reverse direction.
