VACUUBRAND VACUU-PURE 10 Screw Pump Ultimate Vacuum 0.005 mbar (0.0038 Torr) Maximum Pumping Speed  (more)5.9 CFM Inlet/Outlet Connection Small Flange KF DN 25 Features - 10-3 mbar vacuum range - 100% oil-free - No abrasion - No wear parts The dry screw pump VACUU-PURE 10 reliably delivers the benefits of oil-free vacuum technology in the pressure range down to 10-3 mbar. VACUU-PURE 10 combines three important benefits for the user: 100% oil-free, no abrasion, and no wear parts. VACUU-PURE 10 is ideal for clean processes which require a dry and hydrocarbon-free vacuum. The spindles of the screw pump run contact-free and are thus free of abrasion and wear. The screw pump is especially designed for processes in the vacuum range down to 10-3 mbar, however unlike other fine vacuum technologies it can be used across the entire pressure range from atmospheric pressure to its ultimate vacuum. The evacuation of even larger systems from atmospheric pressure down to the 10-3 mbar vacuum range can be done without changing the vacuum pump. VACUU·PURE easily handles high levels of vapor accumulation through its extraordinary condensate compatibility. Thanks to this capability, a gas ballast is unnecessary, avoiding associated disadvantages like the reduction in pumping speed and an increase in noise levels. The integrated regeneration mode enables rapid drying of the pump at the end of the process. This allows sample throughput to be increased significantly as compared to other pump technologies. INCLUDED: The VACUUBRAND VACUU-PURE 10 Screw Pump includes: - 2 x Centering Rings - 2 x Clamping Rings - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
