The OBN992R is a bronze close-coupled rotary gear pump designed for compact, corrosion-resistant fluid transfer with built-in overpressure protection. Featuring 3/8" NPT ports and a Buna (NBR) lip seal, this positive displacement pump includes a factory-set relief valve (50 PSI) for intermittent pressure relief. It is constructed with stainless steel shafts, bronze helical gears for quiet operation, and self-lubricating carbon graphite bearings.
The pump is ideal for water, oils, and mild chemicals compatible with bronze, operating at speeds up to 1750 RPM and pressures up to 150 PSI for lubricants. It supports suction lifts up to 20 feet and is compatible with various motor frames via adapter kits.
Recommended Applications:
Ideal for transferring lubricants, oils, and compatible chemicals in OEM, marine, and industrial systems requiring compact, corrosion-resistant, and pressure-protected performance.
