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Opened in 1989, the facility was originally made up of a single 250,000 sq.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 […]
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 […]
Sensor Monitoring Unit – SMU and New Version of TPM
Schroeder Industries, recognized in filtration and fluid conditioning products, introduces a new version of our TestMate® Particle Counter, TPM and the new Sensor Monitoring Unit, SMU. The new SMU allows live display of the TCM ISO code, TWS water concentration and fluid temperature. Besides displaying the key contamination data the SMU will also store the […]

Muncie’s Optimum Series high performance gear pumps/motors offer high pressure capabilities, and are designed for durability and long life for numerous truck and mobile equipment applications. The Optimum Series offers superior benefits and added value in a cost competitive package unmatched by the competition. Why the Optimum Pump? Patented Opti-Grip technology resists casting separation by […]
Hydraulic gear pump features all-aluminum construction
Dynamic Fluid Components, Inc.’s hydraulic gear pumps have an all aluminum construction gear body with cast iron flange and end plate construction. Displacements range from 0.009 (mini gear pump all aluminum construction) up to 5.43 in³/rev, with different drive shaft options available. Clockwise as well as counter clockwise rotation is available. Dynamic Fluid Components also […]
Pump cavitation: 7 ways to avoid in mobile hydraulic systems
Pump cavitation is one of the most searched topics on fluid power, which is justified, because cavitation is unfortunately an all-too-common cause of pump failure on mobile equipment. Liquids are able to hold dissolved gasses in solution, and the gas saturation level within any liquid is dependent upon the pressure, the temperature and the type […]
New A15VSO high-pressure axial-piston pump from Rexroth
Rexroth developers used state-of-the-art simulation tools in all design stages. The one-piece housing eliminates numerous sealed oil paths, allowing designers to move closer to the goal of a leak-free design. The housing structure, optimized for minimum sound emissions, reduces noise considerably. Subsequently, the airborne noise level has been reduced in average by up to two […]
Smart honing technology puts lift in business for aerospace hydraulic pumps
“We don’t believe it!” – that’s how experienced machinists at Waltz Brothers Inc., a precision grinding and machining operation producing flight-critical hydraulic pumps, reacted to their first encounter with the Sunnen SV-1015, a honing systems that had produced nine bores per part with only 0.000020 in. (0.5 µm) variation, all day long, with essentially no […]
Low-speed, high-torque motor for stationary applications
Eaton Corp., Eden Prairie, Minn., will highlight its latest hydraulic motor technology at its IFPE booth 80230 March 4-8, with the launch of Hydre-MAC,a low-speed, high torque (LSHT) direct drive, radial piston motor. Featuring a cam lobe design—which is a unique design for this type of motor—it is designed for variable speed applications that uses […]
