Key Technical Advantages:

• Vacuum-Hardened Valve Plates: The critical valve plate-to-cylinder interface undergoes rigid vacuum heat treatment and anti-friction coating, immensely fortifying resistance against cavitation erosions and micro-particle score damage.

• Hydrostatically Balanced Piston Shoes: Piston shoes incorporate advanced hydrostatic fluid balance routing, maintaining a precise, microscopic fluid film between the shoe face and swashplate under ultra-high pressures, driving mechanical friction losses down to zero.

• Advanced Modular Electro-Hydraulic Controls: Perfectly mirroring OEM electro-hydraulic control mechanics (such as the EC series code), the electronic interfaces pair effortlessly with industrial PLCs to deliver millisecond-level dynamic responsiveness for pressure and displacement adjustment.

• Ductile Iron Monoblock Housing: Built using heavy-gauge ductile iron cast monoblocks optimized through FEA (Finite Element Analysis) flow profiling, which significantly dampens fluid ripples and mechanical resonances, yielding a noticeably lower acoustic decibel output than generic heavy pumps.

Application Areas:

• Heavy Forging & Forming Presses: Main fluid supply for massive open-die hydraulic forging presses, four-column deep-drawing machinery, and powder metal compacting presses.

• Non-Ferrous Extrusion Metallurgy: Primary hydraulic power for aluminum and copper extrusion profiles.

• Heavy Machine Tools & Transmissions: Large-scale heavy industrial power units (HPUs), gantry planer drives, and closed-loop heavy industrial transmission networks.

• Iron & Steel Mills: Blast furnace clay guns and heavy electric arc furnace (EAF) tilting systems.

Expert Maintenance Tips:

• Pre-commissioning Housing Priming: Prior to initial startup or restarting after extended storage, the pump housing must be fully filled with clean system fluid via the designated filling plug. The case drain line must be attached to the highest physical drain port on the housing and piped directly to the reservoir without obstructions; case internal pressure must never exceed 0.1-0.2 MPa.

• Strict Fluid Cleanliness Integrity: High-pressure axial piston pumps require excellent oil hygiene. The system must be safeguarded with 10μm high-efficiency suction and return filters, strictly maintaining fluid cleanliness indices at ISO 4406 17/14/11 or finer.

• Suction Inlet Vacuum Safeguards: Due to the substantial displacement and high operational speed thresholds of this series, intake lines must be free of restriction or air ingress. Absolute pressure at the suction port must remain above 0.85 bar to eliminate cavitation risks, which will otherwise quickly destroy the piston shoes and swashplate.
