Moroso 22644 4-Vane Vacuum Pump Enhanced Design Natural Aluminum

The Moroso 22644 is an enhanced design 4-vane vacuum pump engineered for high-performance racing engines. Designed to outperform traditional vacuum pump styles, the 22644 achieves greater vacuum levels more quickly, helping to reduce crankcase pressure and improve ring seal for increased power output.

Key Features:

• Enhanced 4-Vane Design – Pulls vacuum faster and more efficiently than original-style pumps
• 13.9% Vacuum Pull – High-efficiency vacuum output for superior crankcase evacuation
• Interior Hard Coating – Hard-coated interior surfaces provide exceptional wear resistance and extended service life
• Lightweight Construction – Weighs less than original-style vacuum pumps for reduced parasitic loss
• Wet or Dry Sump Compatible – Versatile design works with both wet sump and dry sump engine setups
• Virtually Maintenance-Free – Designed for long service intervals with minimal upkeep required
• Natural Aluminum Finish – Clean, corrosion-resistant natural aluminum housing

The Moroso 22644 vacuum pump is an ideal upgrade for circle track, drag racing, and road racing applications where maximum crankcase vacuum and reduced windage are critical to engine performance and longevity.
