مضخة هيدروليكية 708-1S-00262 لـ حفارة صغيرة Komatsu PC27MR-2

1. Product Specifications & Compatibility
This pump is a direct "bolt-on" replacement engineered specifically for the following Komatsu models:

OEM Part Numbers: 708-1S-00262, 708-1S-00261, 708-1S-00161

Machine Fitment: * Komatsu PC27MR-2

Komatsu PC30MR-2 (Verify via serial number)

Komatsu PC35MR-2 (Verify via serial number)

Pump Type: Variable Displacement Axial Piston Pump

System Integration: Designed for Komatsu’s CLSS (Closed-center Load Sensing System), ensuring power is only delivered when the joysticks are engaged, which optimizes fuel efficiency.

2. Technical Features
High Power Density: Compact design allows the pump to fit within the restricted engine compartment of the "Minimum Radius" (MR) chassis.

Integrated Regulator: Features built-in pressure and flow compensators (LS and PC valves) to prevent engine stalling under heavy loads.

Durability: Constructed with hardened cylinder blocks and precision-lapped valve plates to withstand the high-cycle demands of excavation and demolition.

3. Professional Installation Protocol
To prevent premature failure and protect your investment, the following steps are critical during installation:

Case Priming (Mandatory): Before starting the engine, fill the pump housing with clean hydraulic oil through the highest case drain port. Running a piston pump "dry"—even for a few seconds—will cause catastrophic internal damage.

System Decontamination: If the previous pump failed due to internal breakage, you must flush the hydraulic tank, lines, and oil cooler. Metal debris left in the system will destroy a new pump almost immediately.

Filter & Oil Change: Always install a new suction strainer and return filter. Use high-quality ISO VG46 hydraulic oil to ensure proper lubrication and heat dissipation.

Air Purging: After installation, run the engine at low idle and cycle all cylinders (boom, arm, bucket) several times to their full stroke to purge air from the circuit.

4. Why Partner with an Industry Expert?
With over 13 years of experience in Komatsu hydraulic systems, we provide:

Bench-Tested Reliability: Every pump is tested on a hydraulic dynamometer to verify flow, pressure, and response time before shipment.

OEM Quality: We offer Original New or Premium OEM-spec units that match factory tolerances.

Rapid Logistics: Units are secured in shock-proof, export-grade crates and shipped via express carriers (DHL/FedEx/UPS) to minimize machine downtime.
