The OBN970R is a bronze close-coupled rotary gear pump with an integrated relief valve, designed for quiet and efficient fluid transfer in industrial and marine applications. Featuring 3/4" NPT ports and a positive displacement design, this pump ensures consistent flow and pressure with excellent corrosion resistance.
Equipped with helical bronze gears, stainless steel shafts, and carbon graphite bearings, the OBN970R offers smooth, low-noise operation and long service life. The integrated relief valve protects against overpressure, making it ideal for systems with throttling devices.
Recommended Applications:
Ideal for transferring oils, lubricants, and compatible chemicals in marine, industrial, and OEM systems requiring compact, corrosion-resistant, and pressure-stable performance. Not suitable for abrasive or solid-laden fluids.
