High Vacuum Diffusion Pumping System
NST Based High Vacuum Pumping system are used in both laboratory and industrial applications. The standard Vacuum Pumping Systems consists of Rotary Vacuum Pump, Diffusion pumps and other hardware like valves, baffles, collar, gauge and plumbing lines etc., fully integrated and wired. Special Vacuum Pumping Systems are offered with Rotary Pumps, Root Pumps & Diffusion pumps or combination as per customer requirements, Auto Manual Valves, Modular Structure etc The Vacuum Pumping Systems, are trolley mounted with castor wheel for easy movement, and are capable of achieving an ultimate vacuum of 10-6 m.bar. Liquid nitrogen trap given as optional is to minimize the back-streaming of oil vapors, and ensures clean and better ultimate vacuum of 10-6m.bar range. The vacuum pumping systems are fitted with Pirani Gauge to measure the roughing and backing vacuum & Penning gauge for measuring the high vacuum. Option is available for Digital & Analogue type of gauges.
