The SMC-HTE-401 and 541 are single-stage rotary vane vacuum pumps with oil recirculation, designed for high-performance and continuous-duty applications. These pumps are flanged to an electric motor via an elastic coupling for smooth power transfer.
Cooling is managed through an air/oil heat exchanger supported by a centrifugal fan, ensuring optimal operating temperature even under demanding conditions. An integrated check valve prevents oil backflow and air return during shutdown, maintaining vacuum integrity.
The pumps feature an oil mist separator for clean exhaust, with automatic oil recovery for minimal loss and reduced maintenance. Equipped with gas ballasts, the PVL series effectively handles small quantities of vapor, preventing internal condensation and ensuring reliable performance across various industrial applications.
