Product Descriptio

Compatible with Kobelco SK75UR and SK75UR-2 PVD-38-56P hydraulic main pumps, featuring an original dual-plunger structure, integrating the main pump and gear pump into one unit, specifically designed for 7-ton mini excavators. Capable of handling high-frequency heavy-duty conditions such as earthmoving, landscaping, and indoor demolition.

1. Precision plunger distribution plate technology ensures stable pressure output and flow matching the original vehicle's control system, perfectly meeting the original vehicle's travel, swing, and boom composite movement requirements, resolving issues such as stalling, slow movement, and internal leakage.

2. Thickened cast iron pump body resists impact and oil corrosion; the plunger pair uses a high-wear-resistant alloy material, significantly reducing internal leakage losses during long-term high-intensity operation.

3. High and low pressure flow separation design ensures smooth, uninterrupted composite movements, effectively reducing excavator idling vibration, weak boom lifting, and weak breaker hammer.
