Description
The SMC-HTE-PHV 50 K and PHV 75 K are two-stage rotary vane vacuum pumps with oil bath lubrication, designed for high-vacuum applications requiring reliable and continuous operation. These pumps are flanged to an electric motor using an elastic coupling and cooled by forced air through a centrifugal fan.
They include an integrated check valve to prevent oil and air backflow during shutdown and an adjustable gas ballast to reduce condensation when handling small volumes of vapor.
Ideal for evacuating closed systems or maintaining a constant vacuum up to 1 × 10⁻³ mbar (absolute), the PHV 50 K and 75 K deliver efficient, stable, and durable performance across industrial and laboratory settings.
