Used ULVAC DA-40S #9253397 for sale

ULVAC DA-40S is an oil-sealed dry-type scroll vacuum pump. It is engineered to operate quietly and continuously in applications requiring low-pressure rotary vacuum. DA-40S features ULVAC unique AC DRIVE motor and inverter equipment allowing variable speed control to provide superior air extraction performance. ULVAC DA-40S pump is a compact scroll pump, combining the scroll element and motor inside a single, self-contained package. It uses an oil-sealed type pump construction, meaning a small quantity of oil is used to keep the pump body and rotor sealed when the pump is running and pressurised, so air leakage is minimised. This eliminates the need for additional oil traps and controls, offering economical cost of ownership. DA-40S has floating mechanical seals with an anti-contamination design which maintains leakage rates to an extremely low level. This is aided by a Vacuum Isolation System which isolates the pump from the exhaust to ensure it stays clean and free of contaminants. The motor is a direct-drive AC motor with a frequency inverter, allowing precise speed control. This results in a significant energy saving when compared to conventional pumps which require frequency conversion and DC motors. ULVAC DA-40S's AC DRIVE motor also has an accurate speed control unit and direct torque control, providing smooth running and improved speed accuracymeaning it is highly reliable and efficient. It is engineered with rigidity and vibration reduction and an effective cooling machine for maximum pump life. This allows the pump to operate continuously with minimal maintenance and can be used for a wide range of vacuum levels from 0.001 to 99 mbar and evacuation speeds up to 100 l/s (640 m³/hr). DA-40S is a reliable and efficient dry-type scroll vacuum pump which is easily integrated into any production environment, providing low noise, efficient air extraction, low cost of ownership, and minimum maintenance.
