DML Series Air-Cooled Roots Vacuum Pumps

Can withstand large differential pressures and discharge directly to the atmosphere. It allows for smaller models of backing pumps in Roots vacuum systems, reducing investment and energy consumption. Utilizes mechanical seals with API PLAN23 flushing system to completely isolate the working chamber from the oil tank, ensuring "zero"-leakage operation.

Product Features

High Ultimate Vacuum

Up to 13kPa (A) with direct discharge to the atmosphere

Can withstand Large Differential Pressures

It allows for smaller models of backing pumps in Roots vacuum systems, reducing investment and energy consumption

Independent Operation or Series Connection

Can operate as a standalone device (direct discharge to the atmosphere) or in series with screw vacuum pumps or liquid ring vacuum pumps to form a vacuum system, meeting diverse requirements for vacuum levels and capacities

Low Exhaust Temperature

Equipped with an exhaust condenser, the vacuum pump can effectively reduce the exhaust temperature

Backflow Resistance

The two-blade wide-head rotor has a longer sealing line compared with the three-blade rotor, ensuring superior backflow resistance

"Zero" Leakage

Utilizes mechanical seals with API PLAN23 flushing system to completely isolate the working chamber from the oil tank, ensuring "zero"-leakage operation
