Most users of fluid power technology know that water in a hydraulic system can wreak havoc to the system and components, resulting in possible failure. This is why Wix Filters, a global manufacturer of filtration products, has launched what it calls the world’s first proactive molecular hydraulic oil water absorber. The hydraulic oil water absorber […]

Not your grandfather’s gear pump, part 2
Continuing the discussion from last week, the past fifty years saw a continued evolution of the gear pump, which has resulted in higher efficiency, higher pressure and more versatility than was ever previously available. Aluminum alloys are now the most common construction material for the gear pump housing, and hardened steel is used for the […]
Not your grandfather’s gear pump, part 1
The venerable gear pump is so strongly associated with hydraulics that perhaps only cylinders are more prominent in this industry. There is good reason for the popularity of the hydraulic gear pump; they are simple, inexpensive, durable and interminable. I’ve seen them made from about five pieces if you don’t count seals and bolts, and […]
Bosch Rexroth’s largest hydraulics production facility in the Americas celebrates 25 years of operation
Opened in 1989, the facility was originally made up of a single 250,000 sq. ft. building and specialized in manufacturing hydraulic pumps. Now, the Fountain Inn facility is more than double its original size in order to better serve its customers in the region and beyond. Rexroth last year converted an existing industrial warehouse into […]
Beta ratio: Identifying the quality of a hydraulic filter element
I wrote about the ISO 4406 cleanliness code in my last two blogs here and here, and today I’d like to take it a bit further and discuss beta ratios. Beta ratios are important to help us identify the quality of a hydraulic filter element. If using the ISO Code to help identify and specify […]
One valve, three functions
Comatrol, a global leader in the design, manufacture and sale of engineered hydraulic cartridge valves and hydraulic integrated circuits (HICs), today introduces the new SVP08-NCF solenoid valve. Recognizing the market need for single acting cylinder control with a focus on customization and flexibility, Comatrol developed this new solenoid with the intent to deliver three valve […]
Linear sensors to be embedded in hydraulic cylinders
Alliance Sensors Group is pleased to announce the ME Series Linear Position Sensors for embedded use in measuring the ram position of hydraulic and pneumatic cylinders in industrial, mobile, or subsea applications. The ME Series is designed to be drop-in form, fit, and function replacements for embedded magnetostrictive sensors but with much more robust construction […]
Explosion proof pressure transmitters for Zone 1 environments
American Sensor Technologies, Inc. has achieved ATEX certification of its Explosion Proof Pressure Transmitters for Class I Zone 0 Exd hazardous locations. The added approvals enhance the ability for equipment manufacturers to specify AST pressure transducers as the sensors can now operate in both North America and Europe. AST Explosion Proof Pressure Transducers are commonly […]
Rexroth Sytronix SVP 7010 variable-speed pump drive
The new SVP 7010 expands the Sytronix family of ready-to-install variable-speed pump drives offered by Rexroth. With a comprehensive selection of hydraulic-specific functions, it is suited to a broad range of applications. Rexroth has integrated functionality, which in the past required proportional or servo valve technology, into a servo-drive to provide high control accuracy and […]
Accumulator fundamentals … without the math
I’m going to attempt the impossible: I am going to explain the fundamentals of hydro-pneumatic accumulators without using any mathematics. I will use some numbers where needed, but the unfortunate reality is that the proper application of accumulators does require the manipulation of equations. Accumulators are a versatile and valuable tool, but because of the […]
