ACL Series 2 Variable Displacement Piston Pump

With decades of proven reliability, you can rely on Danfoss high-pressure closed-circuit variable piston pumps for all your mobile needs. These heavy-duty hydrostatic pumps are optimized for the most demanding applications. With a peak pressure rating of 500 bar, the Series 2 pump is the go-to variable piston pump for all propel, work, and auxiliary function needs.

With a competitive package and broad control offering, the Series 2 pump meets expectations of a highly accurate, efficient and reliable product in the field. Danfoss Series 2 high-pressure variable piston pump is smaller in size but offers the same product value as the Danfoss Series 1 variable piston pump.

Danfoss Series 2 pump offers a variety of control options including:

• Electronic proportional control
• Manual displacement control
• Forward-neutral-reverse control
• Hydraulic remote control
• Proportional solenoid control

Displacements:

054 - 34 cm3/r (3.316 in3/r)
064 - 66 cm3/r (3.885 in3/r)
075 - 28 cm3/r (4.594 in3/r)
089 - 13 cm3/r (5.439 in3/r)
105 - 4 cm3/r (6.431 in3/r)

Features and Benefits:

• The Series 2 single piece pump housing provides exceptional strength and soundproofing. Danfoss’s cast iron housing has only one major opening versus two openings for competitive pumps. This provides a stronger, more rigid pump housing and reduces the number of gasketed joints.
• The high-strength, one piece swashplate has the swash lever and servo-pin integrated into the swashplate, delivering increased reliability without adding extra weight.
• A large diameter single servo piston permits pump operation at lower charge pressures, minimizing parasitic charge pump losses for increased overall pump efficiency. A large centering spring, housed within the servo piston, returns the pump to neutral in the event of control pressure loss.
• The new integral gerotor type charge pump combines excellent suction/ speed capabilities in a compact design. Several displacement options are available to suit the needs of every application, including tandem pumps.
• A variety of available drive shaft configurations - straight keyed, splined, or tapered - ensures the proper shaft for your application.
• The serviceable bi-metal bearing plate has steel for high pressure capability and a bronze bearing face for high speed capabilities.
• SAE auxiliary mounts: A, B, B-B and C are available with and without charge pump. Excellent torque capability allows high horsepower to work circuits without multiple pump drives.
• The main system ports - SAE code 61 and code 62 - are available with SAE or Metric threads. Opposite side and same side configurations are now available to accommodate a wide range of installations.
