Product details
Rexroth A6VM215, structured with technical clarity and operational workflow:
 
I. Technical Parameter Verification
 
  • Displacement Range: 80–250 cc/rev (A6VM215 typically 215 cc/rev). Match displacement with the original system to avoid flow deficiency or overload.
 
  • Operating Pressure: Rated at 400 bar, peak at 450 bar. Confirm system maximum pressure does not exceed this limit.
 
  • Speed Limits: Maximum 3,900 rpm. Ensure compatibility with drive motor/engine speed.
 
  • Materials & Seals: Cast iron housing, compatible with hydraulic oil media. Temperature range 30–90°C; align with system oil temperature requirements.
 
II. Step-by-Step Replacement Procedure
 
  1. Safety Preparation
 
      • De-energize the system and drain hydraulic oil. Wear protective gear to prevent high-pressure oil splashes.
 
  2. Old Pump Removal
 
      • Disassemble mounting bolts, piping, and electrical connections using wrenches/screwdrivers. Label pipe routing.
 
      • Separate pump body from drive shaft; avoid damaging oil seals or bearings.
 
  3. Cleaning & Inspection
 
      • Remove contaminants from the mounting base. Inspect worn components (e.g., plungers, swashplate, port plate) of the old pump.
 
  4. New Pump Installation
 
      • Align with dowel pins and secure the new pump, tightening bolts evenly to specified torque (refer to Rexroth manual).
 
      • Reconnect piping, ensuring leak-free joints. Replace O-rings and seals.
 
  5. Commissioning & Testing
 
      • Fill with hydraulic oil meeting ISO 3448 standards (e.g., HLP46).
 
      • Start the system; monitor pressure, flow, and noise. Operate for 10 minutes without anomalies before full deployment.
