Campbell Hausfeld VT490000, VT4923 Cast Iron Pump

Campbell Hausfeld VT4923 VT490000 Cast Iron Pump is a 3 HP, twin‑cylinder, single‑stage replacement pump designed for Campbell Hausfeld VTXXX air compressors. Built with solid cast‑iron cylinders, this pump delivers durable performance and efficient heat management in demanding shop settings. It is a direct replacement for VT490000 and VT4923 units and is compatible with VT‑series models rated at 3 HP or higher (VT4923SJ variants included) and ships with a flywheel. The rugged two‑cylinder cast‑iron block and sleeves provide longevity in continuous use, and retailers note this design runs quieter and cooler than aluminum pumps with iron sleeves—claims cited as up to about 35% quieter and around 60°F cooler. This makes it a reliable upgrade for aging VT series compressors that rely on a cast‑iron pumping block.
