Campbell Hausfeld VT490000, VT4923 Cast Iron Pump

The Campbell Hausfeld VT490000 / VT4923 cast-iron pump is a 3-horsepower, single-stage replacement pump head designed for Campbell Hausfeld VT-series compressors and other 3 HP+ models, shipped without a flywheel. It features solid cast-iron cylinders for durable shop performance and is built to retrofit VTXXX units that require a 3 HP or higher pump. The VT4923 family is noted for quieter operation and cooler running compared with aluminum pumps with cast-iron sleeves, with claims of up to 35% lower noise and up to 60°F cooler temperatures under typical use. This version is expressly sold without a flywheel; if you need a flywheel-equipped option, look for the VT4923SJ variant. Suitable applications include replacing a failing or worn pump on Campbell Hausfeld 3 HP+ air compressors in general workshop environments, automotive and woodworking setups, where a durable, cast-iron single-stage pump is appropriate for continued reliable operation.
