SH Scientific Vacuum Pump SH-HV40

SH Scientific Vacuum Pump SH-HV40

Product Description

The SH-HV40 vacuum pump from SH Scientific is a high-performance vacuum system that combines diffusion pump technology with an oil rotary pump. This integrated design allows the pump to achieve ultra-high vacuum levels required for advanced laboratory and industrial applications.

The system provides a pumping speed of 312 L/min and can reach an ultimate total pressure of 2.6 × 10⁻⁴ Pa. This capability allows efficient removal of gases and contaminants from vacuum chambers, making the pump suitable for demanding processes such as vacuum coating, materials research, and high-vacuum experiments.

The SH-HV40 operates with a single-phase power supply and a total power rating of 1.75 kW. The unit includes multiple vacuum port options including KF25, KF40, and KF50, allowing flexible connection to various vacuum systems. The system also includes dedicated ports for air supply and water cooling to maintain stable operating conditions.

The diffusion pump uses specialized diffusion oil, while the rotary pump ensures reliable backing pressure for stable vacuum generation. Its robust construction and efficient cooling system allow long-term operation in research and industrial laboratories.
