Speedaire 2Z630 Air Compressor Pump Cast Iron

The Speedaire 2Z630 replacement pump is a cast-iron, two-cylinder air compressor pump designed to replace VT-series pumps on older Speedaire units and on compatible Campbell Hausfeld, Sears, and Wards equipment. It features a 3-inch bore and rugged cast-iron construction built to withstand the demands of shop use, and it is used in VT-style two-cylinder pumps that can employ either a single-head or a two-piece head assembly, depending on the original configuration. Rebuild kits exist for this bore size (for example 5Z185 and 2Z630 rebuild kits for a 3-inch bore VT pump), underscoring the part’s cross-brand compatibility and the importance of matching bore and head arrangement to your unit. When selecting this pump, confirm the bore, head configuration, and mounting pattern align with your compressor to restore airflow for general pneumatic tooling, automotive maintenance, woodworking, and other light-industrial tasks. Designed as a drop-in replacement for older VT pumps, the 2Z630 can help extend the life of legacy machines without upgrading other components.
