Frequently Asked Questions
Q: What is the primary difference between the N4000R-S15 and other Oberdorfer gear pump models?
The N4000R-S15 stands out due to its integrated relief valve assembly and Viton lip seal combination, which eliminates the need for external relief components while providing superior chemical resistance for specialty applications and marine environments.
Q: Can the N4000R-S15 be used with different types of fluids beyond standard mineral oils?
Yes, the Viton lip seal makes this pump particularly suitable for specialty fluids, including synthetic oils, biodegradable fluids, and chemical-resistant applications where standard elastomer seals would fail or degrade.
Q: Is the relief valve setting adjustable on the N4000R-S15 pump?
The integrated relief valve is factory-set to specific pressure parameters. For applications requiring pressure adjustment, consult Oberdorfer technical specifications or contact an authorized distributor for customization options.
Q: What maintenance requirements does the N4000R-S15 require during normal operation?
Regular fluid level checks, periodic filter inspection, and adherence to recommended maintenance intervals ensure optimal performance and extended pump service life. Refer to the manufacturer's maintenance guide for specific procedures.
Q: How does the bronze construction benefit the N4000R-S15 in marine and saltwater applications?
Bronze provides natural corrosion resistance in saltwater environments and resists rust formation better than ferrous materials, making the N4000R-S15 ideal for marine vessel systems, coastal equipment, and chemically aggressive industrial settings.
