Vacuum pumping System : Vacuum Pumping systems are the most reliable and cost-effective means for producing high vacuum. The vacuum pumping systems are trolley mounted for easy movement and has capable of achieving an ultimate vacuum of10 -6 m.bar with Liquid nitrogen trap. DHVE offers many choices of vacuum pumping system, with different pumping speeds for various application, ranges from DHVE-65D, DHVE-75D, DHVE-114D, DHVE- 150D, DHVE-225F , DHVE300F and Custom built suitable for the most of the vacuum applications. The standard Vacuum Pumping Systems consists of DHVE Rotary Vacuum Pump, Diffusion pumps and other hardware like valves, baffles, collar, gauge and plumbing lines with Pirani Gauge to measure the roughing and backing vacuum & Penning gauge for measuring the high vacuum. etc.
