Open-circuit axial piston pump

Electrohydraulic pump drive motors

Now available in North
America, Danfoss Power
Solutions' (Ames, Iowa) D1 high
power open-circuit axial piston
pump is a high-pressure, highflow variable displacement axial
piston pump developed specifically for open-circuit systems in
the most extreme application
environments. Its robust design
makes it a suitable solution for
mining, heavy-duty construction, forestry, material handling
and marine, oil and gas markets. The addition of the D1
pump expands the Danfoss open-circuit portfolio to include
higher hydraulic power options-up to 160 gpm (600 lpm)-
for OEM customers. Working seamlessly with the new PVG
128/256 high flow valves, OEMs have the ability to extend
hydraulic support for all their high-flow system needs. The
pump's advanced open-circuit control options make it suitable for drill rigs, artificial lift systems, harvesters, mulchers,
wheel loaders, dumpers, pipe-handling systems and more.
The D1 pump is offered with four displacement options from
130-260cc.

The new EHS series compact brushless hydraulic
pump motors with integrated drive electronics from
Allied Motion Technologies
(Amherst, N.Y.) are designed
to directly drive electrohydraulic pumps on large
trucks, buses and other commercial vehicles. Available in
two frame sizes, there are seven models in the series to
meet the requirements of a wide range of vehicle sizes. They
can be optionally supplied with an integrated hydraulic
pump. According to Allied Motion Technologies, EHS series
motors provide vehicle OEMs or their second-tier suppliers
with a fully integrated electric power steering system that
substantially improves vehicle fuel efficiency over all-hydraulic solutions, offers more design flexibility, and reduces
lifetime maintenance and repair costs. The EHS's on-board
electronics enable the motor to serve as an intelligent node
in modern vehicle networks. Thus, the EHS provides an important component of an intelligent motion solution for
electrohydraulic power steering and auxiliary power systems
for heavy trucks and commercial buses.

Bluetooth-configurable electrohydraulic driver

Position sensor

Built to stand up to extreme environmental conditions in mobile and industrial
applications, Sun Hydraulics' (Sarasota,
Fla.) XMD is a high-powered, electronic
control device for electrically operated
hydraulic actuators. The Bluetoothconfigurable, electrohydraulic driver is
both CE and E-Mark rated and serves actuators used in onand off-highway equipment in numerous applications including agriculture, forestry, construction, marine, earth moving
and material handling. The XMD is offered in two models: the
XMD-01 with a single universal input and PWM output and the
XMD-02 with two universal inputs and two PWM outputs.
Sun's mobile driver has the ability to output 0-3000 mA with
±1-mA resolution, which allows it to maintain precision control
when used with pumps, valves, motors or cylinders. In addition to its sleek, compact design, the new XMDs offer a range
of advanced features: simplified configuration via Sun's XMD
mobile phone app; SAE J1939 CAN communication capabilities; and pre-programmed profiles for common tasks.

Representing the latest generation of the SGH wireactuated encoder family,
SIKO's (Buchenbach,
Germany) SGH50 sensor
uses a cable mechanism for
absolute measurement of
hydraulic or telescopic cylinders. The SGH50 now makes it possible to measure distances
up to 5 m (16 ft). Target applications include agricultural machinery, construction machines, municipal vehicles, forestry
machines, piston accumulators and other industrial applications. According to SIKO, the SGH50 performance features
include a significant extension of measurement length and
above-average durability, wide compatibility with various interface protocol-even for applications in which maximum
safety is paramount. Unlike rod-based sensors, the SGH50's
flexible cable completely absorbs vibrations. The hydraulic
medium provides additional damping of any vibration. The
SGH50 is designed in particular for the highest requirements
of mobile hydraulics. The wire-actuated sensor must meet the
prerequisite of an extremely long service life in this context.
