Product Description
All high vacuum pumps rebuilt and sold through FLUIDX have been completely disassembled, cleaned, re-machined and carefully inspected for wear by our factory trained technicians. Units are assembled with new vanes, shaft seals, exhaust valves, gaskets, springs, oil distribution valves and bearings prior to undergoing an extended performance test to meet or exceed OEM specifications. All pumps are then painted, detailed, and pass a final quality assurance inspection prior to shipping.
The Pfeiffer UNO 30M Rotary Vane Vacuum Pump is a single-stage, oil-lubricated pump designed for reliable performance in low to medium vacuum applications. As an upgraded replacement for the discontinued UNO 2.5, it offers a compact design, 30 m³/h at 50 Hz or 35 m³/h at 60 Hz pumping speed, a magnetically coupled single-phase motor, integrated gas ballast, and a built-in high-vacuum safety valve. Compatible with multiple motor voltages, it’s well-suited for global use in lab, industrial, and research settings.
