GRM41 Dry Vacuum Pump System 600 L/min KF40 PMSM Energy Efficient Drive for Semiconductor Vacuum Coating
GRM41 Dry Vacuum Pump System
The GRM41 is a high-performance oil-free dry vacuum pump system engineered for demanding high-purity vacuum processes in semiconductor manufacturing, photovoltaic cell production, and flat panel display fabrication. Equipped with a PMSM (Permanent Magnet Synchronous Motor) energy-efficient drive delivering 0.75 kW output, this compact system achieves an impressive 600 L/min (36 m³/h) maximum pumping speed with an ultimate pressure of ≤1 Pa. The integrated RS485 remote monitoring interface enables seamless integration into automated production environments.
Key Features
- PMSM Energy Efficient Drive: Permanent magnet synchronous motor technology delivers superior energy efficiency with 0.75 kW power consumption, reducing operational costs while maintaining high performance.
- Oil-Free Dry Operation: No oil contamination risk in process chambers, ensuring ultra-clean vacuum conditions essential for semiconductor and photovoltaic manufacturing.
- High Vacuum Performance: Achieves ultimate pressure of ≤1 Pa (gas ballast closed) and ≤10 Pa (gas ballast open), suitable for demanding high-vacuum applications.
- Integrated Gas Ballast System: Built-in gas ballast valve with PT1/4 connection handles water vapor up to 350 g/h, preventing condensation and extending pump service life.
- RS485 Remote Monitoring: Intelligent control interface supports remote operation, parameter monitoring, and diagnostic capabilities for Industry 4.0 integration.
- Compact Lightweight Design: Dimensions of 630*347*400mm and weight of only 54 kg allow easy installation in space-constrained cleanroom environments.
- Low Noise Operation: Noise level ≤65 dB with integrated silencer and check valve, ensuring comfortable working environments.
- Robust Construction: Aluminum alloy and cast iron housing with fluoroelastomer (FKM) seals ensure long-term reliability and chemical compatibility.
- KF Standard Interfaces: KF40 inlet and KF25 exhaust connections for quick, tool-free assembly with standard vacuum components.
