Description du produit

GRM4201 Large Multi-Stage Roots Dry Vacuum Pump — 4200 m³/h High-Capacity Solution

The GRM4201 is a large-scale multi-stage roots dry vacuum pump specifically designed for Load-Lock chambers, transfer chambers, and fast pump-down applications. With 4200 m³/h pumping speed and 13+10 kW dual motor configuration, it meets the demands of heterojunction solar cell manufacturing and lithium battery gigafactories where rapid cycling and high vacuum integrity are critical.

Key Features

Ultra-High Capacity: 4200 m³/h for rapid Load-Lock pump-down cycles
Multi-Stage Roots + Booster: High vacuum with wide working pressure range
Powerful Dual Motor: 13+10 kW permanent magnet synchronous motors
Unique Rotor Design: Optimized for low energy consumption with high efficiency
Oil-Free Clean Vacuum: No oil contamination — ideal for semiconductor and solar
Precision Manufacturing: Advanced CNC-machined rotors with full interchangeability
Dual-End Bearing Support: Ultra-reliable rotor support with minimal vibration
Superior Start-Up Reliability: Engineered for demanding process cycling
Advanced Sealing: Lip seal + labyrinth oil barrier + nitrogen purge — truly oil-free
Water-Cooled Sealed Motor: Eliminates oil leak risk, extends service life
Intelligent Control: One-touch start/stop with I/O and RS485 (Modbus-RTU)
