Single Cylinder Rexroth Hydraulic Pump A10VSO71DFLR/31R-PPA42N00 A10VSO71DR/31R-PPA12N00

Storage guidelines to prevent damage:

• Environment: Store in a dry, dust-free warehouse (temperature 0-40°C, humidity <60%); avoid direct sunlight or proximity to heat sources
• Sealing: Plug all ports (P, S, T, X, Y) with Rexroth original plastic caps (part number R900021345) to prevent contamination; wrap the pump in moisture-proof film
• Preservation: Fill the housing with preservative oil (Rexroth RC 90220) and rotate the shaft 10 turns monthly to lubricate internal components
• Handling: Place the pump on a wooden pallet (avoid metal contact) and do not stack heavy objects (≤50 kg) on top
• Pre-installation: Drain preservative oil and flush with new oil before use

Authentication methods:

• Packaging: Genuine parts have Rexroth's holographic label (changes color when tilted) and batch number (10-digit alphanumeric code); counterfeits often have blurry labels
• Part markings: Genuine piston shoes have laser-etched part numbers (R900...) with clear, non-fading characters; counterfeits use printed markings
• Quality inspection: Genuine seals have uniform texture and Rexroth logos; counterfeits are brittle and lack logos
• Official verification: Use Rexroth's online verification tool
