PFE-21005/1DT Hydraulic Piston Pump
| Hydraulic Oil Change | Every 1,500 ชั่วโมง | Use ISO VG 46 AW mineral oil (or synthetic oil for FKM seals); drain completely to remove sludge and contaminants. |
| Filter Replacement (Suction/Return) | Every 400 ชั่วโมง | Replace 10 μm suction filters and 5 μm return filters—contamination is the #1 cause of piston pump failure. |
| Oil Temperature Monitoring | Continuous | Keep oil temperature ≤70°C (standard NBR seals) or ≤100°C (ซีล FKM). Install an oil cooler if temps exceed limits (high temps degrade oil and seals). |
| Leak Inspection | Monthly | Check shaft seals, flange gaskets, and port connections for leaks. Replace NBR/FKM seals if hardening, cracking, or leakage is visible. |
| Pressure Verification | Every 800 ชั่วโมง | Use a calibrated pressure gauge to confirm system pressure stays ≤21 MPa (ต่อเนื่อง) / 25 MPA (intermittent). Adjust the integrated relief valve if needed. |
