DELVAC DIRECT DRIVEN HIGH VACUUM PUMPS
Delvac Direct Driven High Vacuum Pumps are designed to meet the requirement of high vacuum applications of Freeze Drying. The Pump comprises of two stage offset rotary vane arrangement with a special inbuilt oil pump to take care of oil circulation and to assure continuous silent operation under high vacuum. Operation of the pump with the inbuilt gas ballast valve in open condition warms up the pump thereby preventing vapour condensation inside the pump. This increases the water handling capacity and thereby makes them ideal for use in Freeze drying operations.
