Roper pumps serve as lubrication pumps in the oil and gas markets by efficiently delivering lubricants to various components within machinery and equipment. These pumps are used to ensure proper lubrication of critical parts such as bearings, gears, and seals in pumps, compressors, engines, and other industrial machinery. By maintaining adequate lubrication levels, external gear pumps help reduce friction, heat, and wear, thereby prolonging the lifespan and enhancing the efficiency of equipment in the oil and gas industry.
