 Sauer-Danfoss
offers a wide variety of open circuit products.
Our fixed and variable displacement pumps provide
power for work functions of on- and off-highway
vehicles and equipment in the fields of agriculture,
construction, material handling, many others.
Open Circuit Solutions
Fixed displacement gear pumps and motors and variable
displacement piston pumps are a perfect choice
when equipping applications like forklift trucks,
tractors and road rollers.
Our portfolio includes tailor made pump solutions,
in which several functions are integrated in one
body to optimize size and cost. By combining products
we can offer system solutions for buses, wheel
loaders and other heavy equipment.

 For
light vehicles
such as aerial lifts, greens and fairway mowers
and electric forklifts, Sauer-Danfoss offers SKP1
and SKP2. YCC pumps can be used where compact multisection
pumps are required. These pumps feature: integral
valves, pressure balanced design for high efficiency,
and extruded aluminum bodies for high strength.
For medium sized vehicles
such as tractors, internal combustion engine forklifts
and skid steer loaders, we offer the 25SP aluminum
pump, or where a heavier duty pump is required,
the cast iron D Series. Both pumps feature: SAE
A and B mounts, integral valves, and high-performance
DU bushings.
 For
larger off-highway vehicles
like tractors, backhoe loaders, dump trucks and
telescopic handlers, we offer the SNP3 as well as
the CP180 and CP222 heavy duty cast iron pumps.
Note: Many combinations of the pumps mentioned are
available as multiple units made to fit any need.

Series 45 open circuit pumps can be applied with
other products in a system to transfer and control
hydraulic power. They provide an infinitely variable
flow rate between zero and maximum. The pumps are
compact, high power density units, using the axial
piston concept in conjunction with a tiltable swashplate
to vary the pump displacement.

An integrated hydraulic package is a combination
of pumps, valves, filters, fittings, plumbing, ports,
P.T.O.s etc., designed especially to simplify hydraulic
system installations.
Integrated pumps can be:
|
| |
Simple: |
a) A
tandem gear pump with special inlet adapter
b) a single gear pump with filter and external drive
gear
|
| |
Intermediate: |
A tandem
gear pump with customized mounting, filter mount,
relief valve and external drive gear
|
| |
Complex: |
2 gear
pumps and 1 piston pump with 3 filter mounts, 6
valves, custom mounting flange, 24 ports, gear drive
train, internal galleries replacing plumbing, and
a mount for third party valve.

Cost
effective system integration
 Integrated
package pumps are ideal solutions for manufacturers
of agricultural and on-highway vehicles. Over the
last 12 years, Sauer-Danfoss has participated in
many in-depth studies on the cost effectiveness
of system integration, and it has consistently been
shown that savings of 30% are absolutely realistic
and achievable.
