Mobile Hydraulic Products

Bosch Rexroth’s new mobile hydraulic product lineup for 2022.

BOSCH REXROTH TARGETS ELECTRIC

Bosch Rexroth has introduced a variety of new mobile hydraulic products in 2022, including the eOC electrohydraulic solution, which moves control functions from the hydromechanical controller to the software – electronically controlling hydraulic pumps in open circuits to make mobile machines more flexible and productive.

The modular and scalable Rexroth

K AWASAKI CLOSED LOOP PUMP

eLION platform for the electrification of mobile machinery includes motorgenerators, inverters, gearboxes, software and accessories as well as matching hydraulics.

As part of the eLION platform, the eGFZ spur gearboxes were developed to enable vehicle manufacturers to unlock the full potential of new electric motors, the company said. They are available in two-speed and one-speed versions for a range of applications.

Bosch Rexroth also produces a load sensing valve platform that the company

AEROQUIP BY DANFOSS BRAIDED HOSE

The Aeroquip by Danfoss EC881 Dynamax two-wire braided hose from Danfoss Power Systems features DuraPulse inner tube technology, hybrid wire braid reinforcement and a Dura-Tuff cover. The company said these features enable the hose to outperform standard EN 857 type 2SC hose specifications with a 35% higher pressure rating, 26% higher operating temperature, eight times more abrasion resistance, 67% greater flexibility (1/3 SAE bend radius) and five times more impulse life (1 million qualified impulse cycles). With its higher pressure capabilities, the hose can replace heavy, rigid, four-wire spiral hose in certain applications.

EC881 Dynamax hose is available in -4 through -24 sizes (0.25 to 1.5 in. inner diameter). It is suited for compact construction equipment, agricultural equipment, forestry equipment, mining, oil and gas, refuse truck, aerial lift, railway applications and more.

said is easy to apply to today’s functional demands. The RM10-MPP and RM15MPP (medium pressure platform) are compact, general-purpose, multiapplication load sense directional control valves. ■

The K8V71DT closed loop, tandem, 71cc pump from Kawasaki Precision Machinery (USA) Inc. is designed for compact installations with the outlet ports configured on the same side of the pump for efficient piping layout. It is suited for two-pump, two-motor applications.

The pump is rated for 6000 psi (420 bar) pressure and has a maximum inlet speed of 3300 rpm. Electric and hydraulic displacement controls are available.

SAL AMI LOW-NOISE GEAR PUMP

The 2PSE low noise gear pump from Salami SpA is available with displacements from 4.6 to 26 cm3/rev (0.27 to 1.62 cu. in./rev). Intermittent pressure is up to 280 bar.

The compact, modular pump is suited for applications such as forklifts, agricultural vehicles, municipal vehicles, earthmoving equipment and more. Advantages include an 80% reduction of flow pulsations and noise emissions reductions by up to 7 to 9 dB(A), on average, compared to standard gear pumps, said Salami. In addition, it is designed for vibration reduction and longer pump life.

The unit’s low-noise design includes double flank engagement and tooth profile optimization designed to reduce relative sliding. Specific heat treatment minimizes gear deformation. Axial balancing bushings are optimized to minimize the volume trapped during teeth engagement. ■
