This depends entirely on the application and can vary case by case. The life of the hose is affected mainly by the abrasiveness of the product being pumped, the pump speed (RPM) and how many hours a day the pump is operating. Hose life can be optimized by making the correct pump selection at the beginning of the process. For example, we recommend installing a larger pump running at a very low RPM if the fluid is abrasive and the pump is running 24 hours a day. By using a larger pump at a slower speed, the hose will wear far less, and the life will be extended significantly.
