How do you select hydraulic pumps?
By Josh Cosford, Contributing Editor Hydraulic pumps convert mechanical energy into hydraulic energy, and it goes without saying every hydraulic system requires such a device to transmit controlled force to the actuators of your hydraulic machine. How you select a pump comes down to many factors but working through this guide will help you select […]

Taking hydraulic troubleshooting one step at a time
Contributed by Steve Skinner, on behalf of Webtec LLC It’s probably fair to say that modern machinery is less prone to unexpected breakdowns than its counterparts of 30 or 40 years ago. This is due mainly to an increased emphasis on reliability engineering together with the availability of low-cost sensors, monitoring devices and digital communications. […]
Series V16 variable-displacement, bent-axis motors for mining needs
The Hydraulic Pump and Power Systems Division of Parker Hannifin Corp., highlighted the Pump & Motor Division Europe’s new Series V16 motor at MINExpo earlier in the fall. Series V16 is a new generation of variable displacement, bent-axis motors and a further development of Parker’s V12 and V14 bent axis motor series. The Series V16 […]
How do directional seated valves operate?
In the most traditional sense, a directional control valve simply dictates the direction of hydraulic flow in some regard. The inline check valve is generally regarded as the most basic version of a directional valve, and simply allows flow in one direction while blocking flow in the opposing direction. Their advantage lies in their simple, […]
Komatsu expands its range of hydraulic breakers
Used in a variety of rock and concrete demolition applications from scaling a tunnel, to running a pedestal-boom on a quarry, or tearing out reinforced concrete abutments, breakers are essential tools. Designed and tested for compatibility with Komatsu excavators from the PC210 up to the PC490, Komatsu’s new JMHB-V breaker series helps customers achieve excellent […]
When can you use manual hydraulic valves?
By Josh Cosford, Contributing Editor Although many valves have a manual adjustment, as the knob on a flow control or the hex screw on a relief valve, we generally consider a manual valve to be a directional valve operated by a lever, button or knob. Many hydraulic systems run exclusively with manual valves, like your […]

AEM President, Dennis Slater, who announced earlier this year […]
How are ball valves used to ensure hydraulic safety?
By Josh Cosford, Contributing Editor In fluid power, safety is always a concern. Everyone understands the force capacity of hydraulic actuators (which explains why some YouTube hydraulic press channels have millions of subscribers). Indeed, a high-powered hydraulic press can make nearly any material appear no stronger than modelling clay. It’s wise to respect the power […]
