Frequently asked Questions

A Dry Claw Vacuum Pump generates vacuum using non-contacting claw rotors that compress gas without oil or sealing liquids. This dry compression design ensures clean, contamination-free vacuum performance and low maintenance operation in modern industrial processes.

The pump uses two synchronised claw-shaped rotors that rotate without touching each other or the casing. Gas is drawn in, compressed, and discharged without internal friction, resulting in minimal wear, stable vacuum levels, and long service life.

Two stage pumps provide lower achievable vacuum levels, better stability at higher vacuum ranges, and improved energy efficiency under demanding conditions. They are better suited for critical processes where single-stage pumps struggle to maintain performance or experience efficiency drop-offs.

Dry claw pumps eliminate the risk of oil contamination, reduce maintenance related to oil handling, and offer higher energy efficiency in many applications. They are ideal for clean processes where product quality, environmental compliance, and low operating costs are important.

Yes. JOYAM’s Dry Claw Vacuum Pumps are designed for continuous industrial duty. Robust construction, precise rotor synchronization, and efficient cooling allow reliable operation with stable vacuum performance over extended operating hours.

Dry claw pumps are best suited for handling dry gases. For applications involving high moisture or condensable vapors, appropriate system design or alternative vacuum technologies may be recommended to ensure optimal performance and reliability.

Pump selection depends on required vacuum level, gas type, process conditions, duty cycle, and system configuration. JOYAM’s engineering team evaluates these parameters to recommend a Dry Claw Vacuum Pump solution that delivers efficient, clean, and reliable operation.
