Precise tolerances are key to the performance of Sundyne pumps or compressors. Even the smallest variance can generate inefficiencies within a process flow. Using non-OEM components increases the risk of equipment failure, but these risks can be avoided by using Sundyne Genuine Parts. Sundyne parts are machined accurately using advanced metallurgies and they are custom engineered to fit each specific machine. These precise tolerances are backed by decades of testing and development.
