6. Brand reputation: Select pumps from established manufacturers to benefit from proven reliability and widespread availability of support.
7. Warranty terms: Review the warranty provided by the supplier, as longer coverage periods can offer added peace of mind for professional use.

Storage & logistics

Storing high pressure pumps requires careful handling to preserve their precision and functionality. Keep units in a dry, temperature-controlled environment away from direct sunlight and contaminants. For bulk orders, use sturdy shelving and label each batch with the OEM reference and remanufacturing date. Avoid stacking heavy items on top of the pumps, as this could deform seals or housing. Regularly inspect stored units for signs of corrosion or damage, and rotate stock to ensure older batches are used first. This approach minimizes waste and ensures you always have access to reliable components when needed.
