Dry Compressing Vacuum Pumps Dry vacuum pumps are dry compressing pumps where no lubricants can get into contact with the pumping media. Thus an absolute hydrocarbon free vacuum is the result. Leybold offers different types of dry compressing vacuum pumps which vary in the principle of operation and are used in different fields of application: diaphragm pumps DIVAC, scroll pumps SCROLLVAC as well as screw type pumps SCREWLINE and DRYVAC. DIVAC Diaphragm Vacuum Pumps The dry compressing DIVAC diaphragm pumps were developed for laboratory operations It satisfies the highest expectations in terms of precision, reliability and ease of use. Beside one-stage DIVAC pumps there also are two-stage versions DIVAC L and modular pump systems DIVAC SR, SH and SC available. The DIVAC T-version especially was designed for use as backing pump for (wide range) turbomolecular pumps. DIVAC Backing Pumps for Turbomolecular Pumps The DIVAC T range of diaphragm pumps comprises backing pumps which are used in all applications requiring an especially low base pressure while having to maintain an oil-free vacuum. The DIVAC T pumps have been specially developed as backing pumps for wide range high vacuum turbomolecular pumps. DIVAC 1.4 HV3
