Ingersoll Rand 247-510 Pressure-Lubricated Two-Stage Air Compressor Pump, Heavy Duty, 5-7.5HP

Ingersoll Rand 247-510 Pressure-Lubricated Two-Stage Air Compressor Pump, Heavy Duty, 5-7.5HP 

The Ingersoll Rand 247-510-IR pressure-lubricated air compressor pump is 5hp-7.5hp a high-performance, industrial-grade pump engineered for demanding applications where long duty cycles, high pressure, and maximum reliability are essential. Designed for use in stationary two-stage compressor systems, this pump delivers consistent airflow with minimal maintenance—making it a go-to replacement or upgrade for heavy-use environments such as manufacturing plants, body shops, maintenance facilities, and service fleets.

Unlike splash-lubricated pumps, the 247-510 uses a dedicated pressure lubrication system to ensure vital components like the crankshaft bearings and connecting rods are constantly fed with oil under pressure. This design significantly improves durability, especially in high-heat or high-load conditions. Combined with rugged cast-iron construction and precision-machined components, this pump is built for 24/7 performance.

With a high CFM output and a maximum pressure rating that supports a wide range of industrial air tools and machinery, the 247-510 is ideal for users who can’t afford downtime and need maximum performance from their air system.

The internal Ingersoll Rand part number for this pump is 247-510-IR. 

The 247-510 compressor pump is used with the Ingersoll Rand 5hp and 7.5hp pressure lube compressors that have model numbers which begin with "247P". The 247 pump was also extensively used by DevAir, Devilbiss, and DV Systems.
