Replacement Air Compressor Pumps | Single & Two Stage

An exact lifespan isn't specified, but the R-Series and PL-Series pumps are engineered with rugged cast iron construction, corrosion-resistant valves, and oversized bearings specifically for long service life. This durability is further reflected in the 5-year extended warranty, which provides 100% coverage in Year One and remains prorated down to 60% coverage by Year Five, demonstrating confidence in sustained performance under continuous industrial and field service use.

The R-Series is splash-lubricated, ideal for standard industrial applications up to 175 PSIG, featuring multi-finned cylinders and tapered roller bearings. The PL-Series is pressure-lubricated for extreme-duty use up to 250 PSIG, with a positive displacement oil pump and hydraulic unloader for reliable performance under continuous, high-pressure operation.

Gardner Denver's R-Series and PL-Series replacement pumps cover a horsepower range of 1.5 to 30 HP, with flow capacities from 5.3 to 102.1 CFM, making them suitable for small shop compressors up to larger industrial and OEM compressed air systems.

Yes, both the R-Series and PL-Series pumps are engineered for OEM integration as well as replacement use in existing compressor systems, offering equipment manufacturers a proven, rugged pump platform backed by Gardner Denver's engineering standards and nationwide distributor support.

Pumps include a 5-year extended warranty on parts and labor, prorated from 100% coverage in Year One down to 60% in Year Five. Head valves are covered for Year One only, while the full package warranty runs one year from installation or 15 months from shipment.

Routine maintenance includes monitoring oil levels (2 to 6.5 quarts depending on model), inspecting disc-type valves, and checking bearings. The R-Series' gasketless cylinder/head design and PL-Series' positive displacement oil pump help extend service intervals and reduce unplanned downtime.

The PL-Series pressure-lubricated pumps are specifically designed for extreme-duty applications, operating reliably up to 250 PSI even in off-level conditions. They include a hydraulic unloader for easy loadless starts, making them ideal for demanding continuous-duty industrial and field service environments.
