Danfoss Adds 160-cc Displacement Pump to D1P Portfolio
Danfoss Power Solutions has added a 160-cc displacement option to its D1P line of open circuit high power axial piston pumps.
Key features of the hydraulic pump include:
- pressure ratings of 350 bar continuous and 400 bar intermittent
- flow capabilities of up to 400 lpm (106 gpm)
- angled piston bores and spherical valve plates for efficient operation
- low friction roller-element cradle bearings to improve durability
- integrated charge pump and advanced cylinder-block design for maximum speed rating of 2,500 rpm.
A Durable Hydraulic Pump with Multiple Control Options
Danfoss' latest addition to the D1P axial piston pump portfolio offers a durably designed option capable of meeting the needs of various heavy-duty mobile and industrial machinery applications.
Angled piston bores and spherical valve plates provide high efficiency performance in the rotating group while use of low friction roller-element cradle bearings, standard on all D1P pumps, provided increased durability versus traditional sliding frictional bearings. Per Danfoss, this robust rotating group ensures high reliability in tough applications.
To help better optimize machine performance, the D1P pump is available with various control options including a range of standard pressure compensation and load sensing controls. Mechanical torque control is among these options which prevents engine stall or electric motor overload. Another option is electronic displacement control with manual override to provide simple and precise work function speed control.
Mechanical control configurations are available with ATEX certifications as well to allow use of the pump in hazardous environments.
“The D1P open circuit pump family was designed to provide customers with flexible, robust, efficient solutions for demanding applications,” said Martin Blank, Senior Product Application Engineer, open circuit pumps, Danfoss Power Solutions. “The new size provides our customers with a wider range of choices to find the perfect match for their application. It also addresses a gap in the market for this size pump. As hydraulic pressures and flows trend upward, Danfoss will be there with solutions to meet the evolving needs of mobile and industrial machinery.”
Like other D1P pumps, the 160-cc version can be easily integrated with the PVG 128 and PVG 256 high-flow spool valves from Danfoss to provide OEMs with a full system solution, an increasingly desirable aspect for many. In addition, the 160-cc displacement pump shares the same envelope size as the 130- and 145-cc pumps in the D1P lineup, preventing additional design work for OEMs who may want to adjust the flow needs of their machine models based on varying applicaiton needs.
