DIVAC 3.8 HV3

Diaphragm Pumps

The DIVAC line of vacuum pumps is the logical continuation of diaphragm pump technology, which has proven its quality in decades of service.

This range of vacuum pumps was developed especially for laboratory operations and as backing pumps for (wide range) turbomolecular pumps. It satisfies the highest expectations in terms of precision, reliability and ease of use.

The laboratory pumps for chemical applications:

DIVAC L

The Dual-Stage Diaphragm Vacuum Pumps, which is high chemical resistance pumps for laboratory applications. Ultimate pressure ≤ 8 mbar.

DIVAC L are suited for almost all requirements in the chemistry lab. They are basically corrosion and solvent resistant since their parts in contact with the pumped medium are made of PTFE (Teflon), FFPM (Kalrez) and PVDF (Solef).

Through the laboratory pumps and the three different pumping speeds available for the same base pressure and through the modular design, the optimum pump system can be implemented for every application.

DIVAC 1.4 HV3C

The chemically resistant variant of DIVAC 1.4 HV3 for laboratory applications. Owing to the three-stage design, pressures of 2 mbar can be attained very easily.

Its speed is infinitely variable from 700 to 1600 rpm so that the pumping speed of the pump can be easily adapted to differing requirements. The built-in textured diaphragm is PTFE coated. The valves are made of FFPM thereby ensuring excellent resistance also in connection with aggressive gases.

The backing pumps for clean duty applications:

DIVAC 0.8 T and 0.8 LT

Very compact and low weight backing pump for turbomolecular pumps with low ultimate pressure of 3 mbar (T)/0.5 mbar (LT).

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. They meet the requirements for a dry vacuum and a long service life.

DIVAC T pumps may be used both free-standing and integrated in applications or certain devices, and for this reason they are used in the areas of mass spectrometry, analytical and in general applications.

DIVAC 1.4 HV3 & DIVAC 3.8 HV3

Our dry compressing backing pumps from the DIVAC T series are supplemented by the three-stage DIVAC 1.4 HV3 (Ultimate pressure ≤ 1.5 mbar) and the DIVAC 3.8 HV3 (Ultimate pressure ≤ 1mbar). Like the proven DIVAC T series, these new models also ensure a forevacuum free of hydrocarbons. Owing to their three-stage design, they provide especially within the lower pressure ranges a higher pumping speed and are therefore even better suited as backing pumps for turbomolecular pumps. But they are also used as backing pumps operating in the rough and medium vacuum range to pump clean media

DIVAC 4.8 VT

Model with highest pumping performance and ultimate pressure ≤ 2.0 mbar.
