Frequently Asked Questions
Q: What is the purpose of the integrated relief valve in the N4000R?
The integrated relief valve automatically protects the pump and connected system from excessive pressure by diverting fluid flow when pressure exceeds the valve setting. This built-in protection eliminates the need for external relief valves and provides automatic overpressure protection during operation.
Q: How does the carbon seal enhance pump performance?
The carbon seal technology in the N4000R significantly reduces internal leakage and extends pump service life compared to conventional mechanical seals. This advanced seal design provides reliable sealing under varying pressure and temperature conditions common in industrial applications.
Q: Is the N4000R suitable for continuous duty operations?
Yes, the Oberdorfer N4000R is engineered specifically for continuous duty applications in industrial settings. The bronze construction, integrated relief valve, and carbon seal design handle sustained operation with minimal maintenance requirements and built-in system protection.
Q: What fluids is the N4000R pump compatible with?
The N4000R's bronze construction makes it suitable for use with various industrial fluids including oils, coolants, and standard transfer liquids. Always verify specific fluid compatibility with technical specifications and the relief valve setting requirements.
