A10VSO71DG/32L-PPB32U00 A10VSO45DG/32L-PPB22U00 A10VSO71DR/32L-PPB22U99 German original Dr. Rexroth imported mechanical equipment, efficient and powerful hydraulic pump

A1: Implement a tiered maintenance system:

① Daily: Check oil level (maintain between 1/2-3/4 of the tank), case temperature (<90°C), and listen for abnormal sounds.

② Monthly: Inspect pressure/flow stability via the pump's built-in indicator; retighten all hydraulic connections.

③ 6-month: Replace the 25μm return filter and send oil samples for analysis (check moisture <0.1% and particle count).

④ 12-24-month: Full disassembly--replace seals, bearings, and valve plates; measure piston-cylinder clearance and swashplate wear.

A2: Storage conditions directly affect service life:

① Environment: Keep in a dry, dust-free warehouse (0-40°C, humidity <60%).

② Sealing: Plug all oil ports with Rexroth's original plastic caps to prevent contamination.

③ Preservative treatment: For storage over 3 months, fill the housing with preservative oil (RC 90220) and rotate the shaft monthly to lubricate internal parts.

④ Handling: Avoid stacking heavy objects on the pump; use wooden pallets to prevent mechanical impact.
