2. Compact Tandem Dual-Pump Design: Saves installation space and provides stable flow output, ensuring efficient multi-function coordinated operation.
3. OEM Standard Mounting Dimensions: Direct replacement for the original SPV10/10 pump; allows for easy installation without piping modifications.
4. Factory Pressure Testing: Strict control over internal leakage; effectively resolves issues such as engine stalling under load, sluggish response, pressure drops, and excessive oil temperature.
5. In-Stock Availability: Complete pump assemblies and repair kits (including pump cores, pistons, valve plates, etc.) are available.

• Replace hydraulic oil, oil return filter element, and pilot filter element according to prescribed maintenance periods
• Check for iron filings or copper filings on filter elements during maintenance
• Shorten replacement cycles when using breakers due to accelerated hydraulic oil deterioration
• Avoid prolonged operation without oil and ensure proper air bleeding after component replacement
• Maintain waterproofing - avoid deep water operation and direct water contact with electrical components
• Periodically replace gear oil in slewing reducer and traveling reducer
• Daily inspection of structure for cracks and deformation
• Park excavator on solid, stable, hard surfaces away from rivers, cliffs, or hillsides
• When parking, fully retract bucket cylinder and lower bucket to ground to prevent cylinder damage
