description

The K5V160 hydraulic pump adopts an ultra-heavy integrated swash plate variable structure, with core friction pairs such as plunger, cylinder block and valve plate processed by ultra-precision mirror grinding technology. The internal matching clearance is controlled at micron-level precision, minimizing friction loss during long-term extreme heavy-load operation and greatly improving overall wear resistance and pressure stability. The internal flow channel adopts upgraded fluid dynamic optimization design, which effectively reduces hydraulic circulation resistance and heat accumulation, ensuring gentle temperature rise even during 24-hour non-stop full-load operation. The pump body is integrally cast with high-strength forged ductile iron, featuring ultra-high compression resistance, vibration resistance and impact resistance, adapting to extreme harsh working environments such as quarry strong impact load, mud-water erosion and long-term high-frequency vibration.

advantages

160ml/r Large Displacement, Extreme Heavy-Load Power Reserve: Featuring large-flow 160ml/r standard displacement, the K5V160 main pump provides higher hydraulic pressure and flow output. It perfectly solves the power shortage problem of K5V140 pumps when facing hard rock breaking and ultra-deep excavation, maintaining strong and steady power output for full-load extreme operations of 35–40 ton heavy excavators.
Upgraded K5 Variable Control, Smoother Extreme Compound Action: Adopting upgraded heavy-duty dedicated variable logic, the pump can intelligently adjust flow and pressure according to drastic load changes. The switching between light load and extreme heavy load is smooth without stuttering, effectively improving jitter, slow response and uncoordinated linkage of aging heavy excavators under frequent impact loads.
Premium Full-Load Heat Dissipation, Non-Stop All-Weather Operation: The upgraded internal flow channel greatly reduces hydraulic energy loss and heat accumulation. Even after long-hour uninterrupted full-load mining and rock breaking operations, the oil temperature rises gently, avoiding equipment efficiency reduction and shutdown caused by hydraulic overheating protection.
Ultra-Hard Alloy Core, Long-Term Stable Pressure Holding: Core friction pairs adopt customized ultra-hard wear-resistant alloy and mirror grinding process, achieving extremely low internal wear rate. It fundamentally eliminates common faults such as internal leakage, pressure drop and arm drifting under long-term cyclic extreme load, keeping the hydraulic system in optimal working condition for a long time.
Forged Heavy-Duty Pump Body, Extreme Condition Resistance: The integral forged ductile iron pump body has super compression, vibration and impact resistance. It can stably cope with extreme working conditions such as violent quarry impact, strong muddy water corrosion and long-term high-frequency vibration, with no deformation, oil leakage or cracking after long-term use.

FAQ

Q1: What tonnage of excavators does the K5V160 hydraulic pump apply to?
A: The K5V160 hydraulic main pump is exclusively designed for 35–40 ton heavy excavators, focusing on high-intensity mining, super deep foundation and large-scale earthwork heavy-duty scenarios, with strong compatibility with mainstream 35-ton class heavy machinery.
Q2: What symptoms indicate the K5V160 pump needs replacement?
A: If the excavator has weak rock breaking power, slow full-machine compound actions, insufficient heavy-load traveling power, frequent pressure drop, abnormally high hydraulic oil temperature and jittery linkage during mining operations, the original main pump is severely worn and fails to hold pressure, requiring timely replacement.
Q3: Is equipment modification required for K5V160 pump replacement?
A: No modification is needed. The K5V160 pump is manufactured strictly according to original factory heavy-duty standards with fully consistent hole positions and high-pressure interfaces, supporting direct plug-and-play installation for rapid on-site maintenance.
Q4: What is the difference between K5V160 and K5V140 pumps?
A: The K5V160 has larger displacement, higher pressure grade and stronger extreme load resistance, suitable for 35–40 ton heavy excavators and mining extreme working conditions. The K5V140 is only applicable to 28–33 ton medium-heavy equipment, with insufficient power reserve for ultra-heavy rock breaking operations.
Q5: How to maintain the K5V160 main pump to extend service life?
A: Regularly replace genuine high-grade hydraulic oil and filter elements to ensure clean oil circulation. Avoid long-term extreme overload operation. Regularly check high-pressure pipeline leakage and blockage. Standard daily maintenance can effectively delay core wear and main pump aging.
