Dry Running Pumps: What is it and Why is it Harmful?

August 18th, 2019

Hydraulic oils transmit and amplify actuator-controlled forces. They deliver those kinetic energies to mobile vehicle pistons and crane booms. In addition to that principal function, the fluid also cools and lubricates the fast-moving machine assemblies inside a hydraulic system. Hydraulic pumps, because they’re participants in this balanced fluid conveyance process, should never run dry. Regrettably, […]

Criteria for Hydraulic Filter Selection

August 4th, 2019

When choosing a hydraulic filter, the fluid sieving architecture is expected to satisfy a long list of performance requirements. There’s a brief pause while product parameters are pored over. With all possible selection criteria reservations finally settled, the contamination blocking component is installed. Two separate system stages have been reviewed during this process. First came […]

The Importance of Oil Coolers in Hydraulic Systems

July 15th, 2019

Whenever possible, complex hydraulic systems utilize hassle-free support systems. Take oil coolers, which are designed to prevent hydraulic fluids from overheating. While it’s true that cleverly engineered parts and superbly fabricated mechanisms help keep system oils temperature-controlled, such impeccably designed assemblies come with high price tags attached. Taking the route that doesn’t incur such high […]

Understanding the Functions of Manifold Valves in Hydraulic Systems

July 3rd, 2019

Whatever the circuit type, be it electrical or hydraulic, the interconnecting lines in that circuit can’t work without control elements. Switches and transistors take up this duty in voltage-regulated circuits. In hydraulic/pneumatic applications, valves take their place. This is fluid control technology, not electric current, but the ruling principles are similar. For valves, pressures and […]

Understanding Pressure Compensation in Hydraulic Systems

June 19th, 2019

Pressure compensation systems operate a little like feedback-based electronic systems. That’s not exactly a surprise, not when hydraulics circuits can become every bit as complex as any electronically based wiring. At any rate, the similarities are there for everyone to observe. When an output change occurs, a fraction of that change is sent back to […]

Why Bearing Alignment is Critical to Pump Life

June 3rd, 2019

Bearing alignment difficulties impact all shaft-driven systems to some degree. In a ventilation fan, a poorly aligned bearing will shorten the lifespan of the appliance, and then a cool room will fill up with stifling heat. Noise, screeching vibrations, all kinds of nasty headaches will crop up until the fan stops working. With pumps, though, […]

Key Components in Filtration and Conditioning of Hydraulic and Pneumatic Pumps

May 15th, 2019

Just like a healthy circulatory system, hydraulic fluids perform more efficiently when they’re cleaned and conditioned. A person feels weary if their kidneys aren’t doing their job. Likewise, an unresponsive mobile hydraulics system can probably blame a fouled-up fluid contaminant. Knowing this, a repair engineer checks the hydraulic oil. If that oily medium is fouled […]

Understanding Parker Pumps Medium Pressure Industrial Piston Pumps

May 6th, 2019

Parker provides a large range of medium pressure industrial piston pumps. Predictably, since this is one of the most recognized names in the hydraulics sector, each series packs a host of performance-tuned features. To achieve this feat, the Parker Pumps engineering chiefs have divided their medium pressure products into four groups of intermediate-strength piston pumps […]

What is Hydrostatic Leak Testing in Pumps?

April 15th, 2019

If fluid pressures power hydraulic components, the tests used to inspect those system parts should also be fluid-based. That’s just common sense. Accordingly, engineers employ their finest hydrostatic leak testing paraphernalia when they’re running fluid circuit punctures to ground. So far so good, then, but what is hydrostatic leak testing all about? From question to […]

Hydraulic Pressure Intensifiers: How Do They Work?

April 4th, 2019

Hydraulic systems are impressive constructs. Arguably speaking, they’re even more sophisticated than an electrical circuit. In point of fact, most modern fluid-based systems include electrical and electronic elements, which either add regulatory control or feedback signals to the equipment. Among that mass of performance-engineered components, hydraulic pressure intensifiers perform their own unique services; they provide […]
