We Can Provide You with OEM/ODM Solutions
As a professional automotive pump manufacturer, KITAKI Pump provides OEM/ODM services for you.
Obtain SolutionsOKAYPARTS is one of the leading manufacturers, suppliers and exporters of automotive engine water pumps in China, specializing in automotive water pumps since 2006. We manufacture and supply engine water pumps with the latest equipment and technology for various brands of passenger cars at market leading prices to our valuable customers across the globe.
OEM support: Covering the water pump mold database of Volkswagen MQB, Toyota TNGA and other platforms
After-sales market: 2000+ models support accurate matching of VIN codes (including JIS/SAE standard threads)
Special customization: Desert version (anti-sand filter), high-cold version (low-temperature starting torque optimization)
Impeller innovation:
Carbon fiber reinforced PPA impeller: 60% lighter than traditional steel, resistant to ethylene glycol corrosion
Magnetic drive sealing technology: eliminate shaft seal friction, leakage rate <0.01ml/h (surpassing IP67)
Fast delivery:
Reverse mapping of new model water pumps completed in 15 days (including 3D printing trial installation verification)
Inventory spare parts barcode traceability system
Each water pump adopts a five-dimensional precision structural system to ensure reliability and life under extreme working conditions:
Heavy-duty combined bearing system
Including deep groove ball bearing and thrust bearing composite structure, preload accurate to ±0.01mm
Nano-ceramic rolling element + self-lubricating coating, through DIN 51524 standard 10,000-hour durability test
Press-fit hub assembly
Interference fit tolerance is controlled at H7/p6 level (IT5 precision), eliminating the risk of axial movement of the pulley
Surface phosphating treatment + micro-arc oxidation, salt spray corrosion resistance up to 1,200 hours (exceeding ASTM B117 requirements)
Precision machined housing
Ductile iron QT500-7 material, CNC five-axis machining center molding, wall thickness tolerance ≤±0.2mm
Integrated labyrinth seal groove design, with triple radial seal ring to achieve IP67 protection level
Combined dynamic seal assembly
Silicon carbide ceramic dynamic ring + fluororubber static ring constitute the main seal, leakage rate <0.001ml/h
Magnetic fluid auxiliary sealing system, compensates for material deformation at extreme temperatures (-40℃~150℃ working condition verification)
Optimal impeller clearance control
CFD fluid dynamics optimizes blade angle (adjustable from 12° to 35°), flow wave Dynamic rate ≤2.5%
Laser measurement and calibration of the impeller-pump casing clearance to ensure the golden efficiency range of 0.15-0.25mm
100% factory test procedures:
3D scanning comparison (deviation from OE parts <0.05mm)
6,000rpm overspeed dynamic balance test (residual imbalance <1.0g·mm/kg)
Burst pressure test (≥8bar pressure maintenance for 30 minutes without leakage)
Original specifications beyond design:
Reverse engineering is used to crack the patented structure of Bosch/Aisin, etc., and the flow head index is increased by 5-8%
Impeller anti-cavitation performance has passed SAE J2527 standard verification, life is 30% longer than the industry benchmark
Adaptability verification technology:
Digital fitting based on VIN code database (covering 92% of mainstream models worldwide)
Provide 3D model (STEP/IGS format) and real vehicle interference analysis report (accuracy 0.1mm level)
High temperature desert version: Add centrifugal sand and dust filter (interception efficiency > 95%)
Extreme cold start version: low temperature pre-lubricated bearing system (-45℃ starting torque ≤3.2N·m)
Hybrid dedicated: CAN bus compatible interface, support PWM precise flow control
Dimensions | Mechanical water pumps | ||
Drive mode | Belt drive (energy consumption accounts for 1.5% of engine power) | Motor direct drive (independent control) | Provide low friction pulley (reducing energy consumption by 0.8%) |
Control accuracy | Speed is linearly bound to engine | PWM stepless speed regulation (±2% flow error) | Optional electronic bypass valve to achieve flow fine-tuning |
Failure mode | Water seal leakage (accounting for 63%) | Circuit board overheating/impeller slippage | Triple redundant seal + vibration monitoring sensor |
Cost structure | Unit price $18-35 (scale advantage) | Unit price $80-200 (including controller) | Compatible with original factory interface, replacement cost reduced by 40% |
