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
Corrosion-Resistant Material
Hastelloy coating and superalloy materials are available for varying corrosive operating conditions
Easy Maintenance
Enables in-situ cleaning of the pump chamber without disassembly or removal of inlet/outlet pipelines
