Истории успеха
End Equipment Manufacturers (OEM Customers) Wind power equipment manufacturers: Mainly customers for DKF dedicated wind power pumps, including wind turbine gearbox makers like Vision Energy, Dalian Heavy Industry, Taiyuan Heavy Industry, Weili Transmission. DK-F version is customized to resist alternating vibration and frequent variable speed of wind turbines. Heavy machinery & reducer manufacturers: Manufacturers of large industrial reducers, metallurgical rolling mills, mining equipment, const
Technical & Operational Effects
Ultra-low noise performance
Adopted helical gear meshing structure, running noise is 3dB lower than traditional straight gear pumps, greatly improving workshop and wind turbine cabin working environment, meeting low-noise factory standards.
High volumetric efficiency & energy saving
Volumetric efficiency ≥95, minimal internal leakage. Under the same flow demand, matching motor power is reduced, cutting long-term power consumption for continuous-operation equipment.
Strong medium adaptability
Covers kinematic viscosity range 12–20000 cSt, compatible with thin hydraulic oil and high-viscosity heavy lubricating grease; works steadily at fluid temperature -40℃ ~ 100℃.
Outstanding durability & low wear
Precision-machined helical gears and copper bushings reduce friction loss; component wear is reduced by 40% vs ordinary gear pumps, extending pump service life and lowering replacement frequency.
Built-in integrated safety protection
Standard built-in relief valve (adjustable 5–25 bar) provides instantaneous overpressure protection, preventing pipeline and gearbox damage caused by pressure spikes. No extra separate relief valve needed for basic circuits.
Wind power customized upgrade (DKF model)
Enhanced anti-fatigue and anti-vibration structure, adapts wind turbine frequent alternating loads; wind farm operation data shows gearbox lubrication failure rate drops significantly after replacing with DKF pumps.
Complete matching compatibility
Perfectly matched with DEO self-circulation coolers, plate water coolers, forming one-stop lubrication & cooling system solutions for customers, simplifying system design and procurement.
2. Commercial & Customer Value Achievements
Cost advantage vs imported pumps
Performance matches European KRACHT/NOP imported gear pumps, while overall procurement cost is about 30% lower; overall system operation and maintenance cost reduced for end customers.
Full industrial chain delivery capacity
Self-owned pump produc
Stable product performance and high cost-effectiveness
