How to choose
Selecting the right high pressure pump involves more than matching the OEM reference; it requires evaluating condition, packaging, and supplier reliability to avoid costly mistakes.
- Condition: Opt for a remanufactured pump with a core deposit system to ensure traceability and environmental compliance.
- Packaging: Choose pumps shipped in protective, anti-static containers to prevent damage during transit and storage.
- Consistency: Prioritize suppliers with a proven track record of delivering pumps that meet pressure and flow rate specifications.
- Rotation: Select a wholesaler with frequent stock turnover to minimize the risk of receiving outdated or improperly stored components.
- Compatibility: Verify the pump’s fitment with your specific engine code and model year to avoid installation issues.
- Supplier reliability: Work with a distributor who offers transparent lead times and responsive customer support for urgent orders.
- Warranty terms: Review the warranty coverage provided by the remanufacturer to protect against premature failures.
Storage & logistics
For workshops and garages, proper storage of high pressure pumps is essential to maintain their performance and longevity. Store pumps in a dry, temperature-controlled environment away from direct sunlight and contaminants. Avoid stacking heavy items on top of the packaging to prevent deformation of the pump body or internal components. Regularly inspect stored pumps for signs of corrosion or seal degradation, and rotate stock based on the first-in, first-out principle to ensure freshness. When handling, use gloves to prevent contamination from skin oils, and always store pumps in their original packaging until installation to preserve protective coatings and labels.
