Overview

The HT high throughput series is the pinnacle of our diffusion pump knowledge with technology aimed specifically at industrial users. Edwards diffusion pump is designed for all light and heavy duty industrial applications. The robust construction gives high pumping speed at high pressure. The cast and machined aluminium interior provides consistent performance, while the stainless steel body prevents corrosion and ensures process cleanliness. These pumps are designed to give a high throughput (pressure multiplied by pumping speed) at 4 × 10-3 mbar making them ideal for industrial processes that involve large quantities of gases.
