Campbell Hausfeld VT490000, VT4923 Cast Iron Pump

Campbell Hausfeld VT490000 / VT4923 Cast Iron Air Compressor Pump is a 3 HP, single-stage replacement pump built around a rugged cast-iron body and a 10-inch flywheel. Designed to fit Campbell Hausfeld VT-series compressors rated at 3 HP and above, this pump head (VT4923) is used as a direct retrofit on compatible VT models to restore or improve air output. The 10-inch flywheel helps maintain smooth belt drive and stable rpm under typical load, while the cast-iron construction resists wear during repeated cycling in workshop environments. The VT4923 designation identifies the iron pump head used on these VT-series units, making it a common retrofit for older Campbell Hausfeld equipment, and installation should ensure proper belt alignment and compatibility with your specific VT-series model.
