Frequently Asked Questions

▶️ Question: What is a bare pump?

Answer: A bare pump is the core compressor assembly without a motor or tank. It’s used to replace the failed pump on an existing air compressor or as the foundation for a custom-built unit.

▶️ Question: Can I replace only the pump on my air compressor?

Answer: Yes. If your motor and tank are still in good condition, replacing just the bare pump restores performance and saves the cost of buying a complete compressor package.

▶️ Question: What’s the difference between oil-less and lubricated pumps?

Answer: Oil-less pumps, like those from Anest Iwata, deliver clean, oil-free air for sensitive applications, while lubricated two-stage pumps from Ingersoll Rand provide higher CFM and durability for industrial use.
