VEVOR 3-Cylinder 10HP Dual-Stage Head
VEVOR’s 10HP air compressor pump head features a 3-cylinder, oil-lubricated design that delivers 17.5 CFM at 90 PSI with a maximum working pressure of 185 PSI. This dual-stage V-type pump is built for demanding workloads, providing sustained airflow for tire inflation, spray painting, woodworking, and more. Note that a motor is not included. The belt-driven configuration helps minimize bearing displacement and reduce vibration when properly aligned. Key design elements include a precision cylinder, robust intake and exhaust valves, efficient heat dissipation fins, and an oil observation mirror for easy oil level monitoring.
VEVOR 10HP, 3-Cylinder Dual-Stage Head
This 3-cylinder, dual-stage head is designed for high-demand setups with rapid air delivery and elevated working pressure. The oil-lubricated pump head uses a belt-driven system to optimize performance and reduce vibration with correct alignment. Its cast-iron construction and heat-dissipation features support longer service life in workshop environments where multi-stage compression is needed.
3HP Cast Iron Pump Replacement
Designed as a heavy-duty single-stage, two-cylinder pump for Campbell Hausfeld VT4923 and similar models, this head delivers up to 12 SCFM at 90 PSI—well-suited for 60-gallon tanks. It fits a broad range of brands with standard mounting patterns (6.5″ x 5.875″ center-to-center). A 3HP motor (15A at 220V or higher) is typically required for optimal operation, making it a versatile retrofit option in multi-stage systems that still rely on a higher-output head.
CS2065A 2–3 HP Replacement Head
CS2065A is a versatile single-stage, two-cylinder pump designed for 2–3 horsepower motors. It outputs about 7 CFM at 1180 RPM with a peak RPM near 1200, making it a practical choice for compressors under 40 gallons. It supports both 110V and 220V configurations, enabling compatibility with common workshop electrical setups while serving as a bridge between smaller, multi-purpose heads and larger, multi-stage systems.
2HP Cast Iron Pump Replacement for Various Brands
This heavy-duty two-cylinder, single-stage pump is designed for compressors with tanks up to 40 gallons. It delivers up to 5.5 SCFM at 90 PSI and serves as a reliable replacement for Campbell Hausfeld VT4823 and several other popular models. The cast-iron construction with an aluminum head aids heat dissipation, while an oil sight glass allows easy monitoring and maintenance of oil levels for longer life in demanding setups.
InSyoForeverEC 21CFM Double Stage Head
Featuring a 4 kW motor equivalent drive, this twin-cylinder head is rated for 21 CFM at 0.6 m³/h and operates up to 175 PSI. The iron construction and complete accessories support robust performance with faster inflation and lower noise levels. It emphasizes a dedicated cooling design and a reinforced valve system to maintain performance under sustained multi-stage cycles.
Buying Guide: Key Considerations for 3 Stage and Multi-Stage Pump Heads
- Stage configuration and max pressure: Multi-stage heads are designed to deliver higher pressures with efficient air compression. Verify whether the pump is labeled as single-stage, dual-stage (two-stage), or triple-stage to ensure compatibility with your system’s tank size and required output.
- Material and build quality: Cast iron bodies with brass or steel components offer durability and heat resistance, which matter in prolonged use. Oil-lubricated designs can improve efficiency and longevity but require regular oil maintenance.
- Motor compatibility: Confirm the motor horsepower, voltage, and amperage needed to drive the pump. Many heads specify motor requirements (e.g., 3HP, 5HP, 10HP) and voltage (110V vs 220V). Ensure your compressor frame and electrical circuit match.
- Belt-driven vs direct-drive: Belt-driven designs reduce vibration and wear but require proper alignment and tension. Direct-drive heads are simpler but may transmit more vibration. Choose based on installation space and tolerance for vibration.
- Oil monitoring and maintenance: Look for an oil observation mirror or clear sight glass and easy maintenance features. Regular oil changes and level checks help sustain performance and extend life, especially in high-cycle multi-stage systems.
- Mounting pattern and compatibility: Check mounting dimensions (center-to-center, bolt pattern) to ensure a proper fit with your existing tank and frame. Universal mounting compatibility can simplify retrofits across brands.
- Noise and cooling: High-stage heads generate more heat and noise. Features such as cooling fins, cast-iron construction, and effective exhaust paths improve reliability in workshop environments.
- Repairability and availability of parts: Consider whether replacement valves, rings, and gaskets are readily available for the chosen head. This can significantly affect downtime and total cost of ownership.
- Application fit: For tasks like tire inflation, spray painting, or woodworking, match the head’s CFM at the target pressure to your tool requirements. Higher CFM at relevant PSI leads to smoother operation and less cycling.
