Variable Axial Piston Pumps for Open Circuit C series

Variable Axial Piston Pumps for Open Circuit C series

Product catalog summary

Specifications:
The document specifies that variable axial piston pumps have a maximum operating pressure of 25 bar. It details the adjustment range and specifies connections for pressure, suction, and control ports.

Temperature and Fluid Selection:
The operating temperature range for hydraulic fluids is from -40°C to +100°C. It recommends selecting high-class hydraulic fluids, such as VG 68, to ensure optimal performance within the specified temperature and viscosity range.

Hydraulic Fluids:
High-quality hydraulic fluids with anti-corrosion, anti-oxidation, and anti-foaming properties are recommended. The use of mineral oil group HLP according to DIN51524 is advised, with any deviations requiring consultation with the manufacturer.

Fluid Viscosity Parameters:
Optimal viscosity is between 20-30 mm²/s, with a maximum starting viscosity of 1500 mm²/s and a minimum short-term viscosity of 10 mm²/s.

Filtration Requirements:
Filtration is crucial to maintain fluid purity according to ISO 4406 standards, with a required purity grade of at least 19/17/14 at high temperatures.

Shaft Seal:
The shaft seal's lifespan depends on axial velocity and pressure drainage, with short-term pressures up to 10 bar permissible. Increased pressure pulsations can reduce seal life.

Installation Recommendations:
The axial piston unit must be filled with hydraulic fluid and air bled during installation. Guidelines are provided for installation positions, both below and above the reservoir, with a maximum permissible suction height of 800 mm.

Mounting Options:
Various mounting options are detailed, including below-reservoir and above-reservoir installations, with advice on necessary distances and heights to prevent fluid drainage and ensure proper operation.

Installation Guidelines for Axial Piston Units:
Specifications: The unit must be installed below the minimum fluid level in the tank, ensuring it is completely submerged. Units with electrical components should not be installed below the liquid level.

Mounting Options: Various configurations are available, including options for air tackling and filling, denoted by codes such as L, L1, S, and SB.

Installation in the Tank:

Suction Line (S): Ensure proper connection to avoid direct suction of heated fluid.
Filling and Air Removal (F): Follow proper procedures to ensure system integrity.
Drain Line Connection (L, L1): Properly connect to facilitate fluid drainage.
Damping Wall (SB): Use to minimize vibrations and noise.

Minimum Requirements:

Loading Depth: Minimum 200 mm.
Distance to Tank Bottom: Minimum 100 mm.
Height to Prevent Fluid Drainage: Minimum 25 mm.
Maximum Suction Height: 800 mm.

Design Considerations: Ensure sufficient distance between the suction and drain lines to prevent the direct absorption of heated fluid back into the suction line.
