Abstract: A vacuum system configured to mitigate damage or risk associated with a pump malfunction (e.g., an imbalance, a catastrophic failure, etc.). An exemplary vacuum pump includes a housing; a vibration isolator coupled to the vacuum pump housing and configured to isolate vibrations generated by the vacuum pump during operation; and a stop structure disposed between the vacuum pump housing and an adjacent fixture. The stop structure configured to prevent displacement of the vacuum pump housing relative to the fixture above a threshold amount, wherein the displacement of the vacuum pump housing is configured to be within the threshold amount during normal operation. The vacuum system may further include a collar configured to limit an axial displacement of the pump.
