PERMCO Gear Pump 5527497 Dedicated Working Hydraulic Pump for SEM 660D Wheel Loader
Hydraulic Working Pump Assembly BOM (Peripheral Linked Parts)
| No. | Part Name (EN) | Recommended Part No. / Ref. | Qty | Function & Maintenance Notes |
|---|---|---|---|---|
| 1 | Hydraulic Gear Working Pump | 5527497 (PERMCO) | 1 | The main core actuator. Must be replaced as a whole unit if internal galling, pressure drop, or casing wear occurs. |
| 2 | Flange O-Ring Seals | Match standard flange size | 2 | One-time use item. Must be replaced to prevent high-pressure hydraulic oil leaks at the suction and delivery ports. |
| 3 | Split Flange Clamps | Match pump port specifications | 2 | Secures the high-pressure steel lines to the pump body; prevents loosening caused by continuous pressure pulsations. |
| 4 | Hydraulic Return Filter Element | SEM 660D Dedicated Filter | 1-2 | Mandatory Replacement. Essential to trap any residual metallic debris generated by the old failed pump. |
| 5 | Pilot Hydraulic Filter Element | SEM Hydraulic System Std | 1 | Protects the pilot control valves and main multi-way valve spools from tiny particles during initial startup. |
| 6 | Anti-Wear Hydraulic Oil (46# / 68#) | Grade depends on ambient temp | Var. | The hydraulic tank must be drained and flushed. Running a new pump with contaminated or emulsified old oil will void the warranty. |
Application Scenarios
1. Open-pit mines and quarries: Delivers ultra-high hydraulic pressure to provide powerful breakout force for the bucket, enabling the prying and excavation of compacted soil, rock, and blasted ore.
2. High-tonnage bulk material handling: Supplies constant, high flow rates in steel mills, power plants, or large coal yards to drive boom cylinders, rapidly lifting loads exceeding 6 tons to heights over 3.1 meters for dumping.
3. Ports and logistics hubs: Achieves exceptional volumetric efficiency to significantly reduce boom lifting and unloading cycle times, meeting the rigorous demands for high-frequency, high-efficiency bulk cargo handling at terminals.
4. Specialized operations requiring extreme weather resilience: Utilizes unique internal sleeve bearings and pressure-compensating side plates to ensure continuous, heavy-load operation in harsh environments-ranging from extreme cold (enabling startup with high-viscosity fluid at low temperatures) to scorching heat (maintaining pressure without leakage despite high temperatures and low fluid viscosity).
