At OkayParts, we specialize in custom automotive pump solutions. Whether you need a replacement for a rare model, an upgrade for better performance, or a pump designed from scratch for a new vehicle line, we turn your requirements into a reliable, ready-to-install part—delivered in 60 days.
Water Pumps: OEM-matching or high-flow designs for engines from compact cars to luxury sedans.
No matter the make—Toyota, BMW, Ford, Hyundai, or beyond—we’ll build a pump that fits your car’s engine bay like it was factory-made.
We don’t just “modify” existing parts. We engineer from the ground up, with a focus on details that matter:
Aluminum Alloys (6061): Lightweight and corrosion-resistant, ideal for modern EVs and fuel-efficient cars.
Cast Iron: Durable for high-mileage vehicles or engines with steady heat output.
Reinforced Nylon: For impellers, balancing strength and weight to reduce engine load.
Seals: Viton® or EPDM rubber, tested to handle passenger car engine temps (-30°C to 120°C) without leaking.
Ensures tight tolerances: ±0.015mm for shafts, ±0.02mm for mounting holes—no misalignment, no leaks.
Automated assembly lines with in-line checks: every bearing, seal, and impeller is fitted to exact specs.
Post-production testing: each pump is pressure-tested (up to 12 bar) and spin-tested (1,500–6,000 RPM) to mimic real-world use.
Technical guidance including text, image documentation, and remote video support
Custom material selection and treatment for specialized applications
Support for multiple delivery modes: land, sea, and air logistics
Design optimization for cost, efficiency, and market competitiveness
Post-delivery support, maintenance recommendations, and troubleshooting
Flow rate: from low to high capacity systems
Operating pressure: low pressure to high pressure pumps
Power: ranging from fractional horsepower to industrial levels
Material: aluminum, cast iron, stainless steel, and specialized alloys
Structural customization: sealed, open, direct-drive, or belt-driven options
Tell Us What You Need: Share your car model, engine details, and any specs (or problems with existing pumps).
Design & Approve: We send a 3D design and quote within 5 days. Adjust as needed—we’ll refine until you’re happy.
Prototype & Test: We build one sample for you to check fit and performance. Approve, and we move to production.
Build & Ship: Your custom pumps are manufactured, tested, and shipped—all within 60 days of final approval.
