Edwards LR1C150 – single-stage liquid ring vacuum pump
The LR1C150 delivers 165.6 m³/h at 50 Hz and 194.4 m³/h at 60 Hz and, with water as the operating liquid, reaches an ultimate pressure of 33 mbar. Liquid ring pumps compress the gas in a rotating liquid ring; the operating liquid carries away the heat of compression. They tolerate vapours, moisture and entrained liquid.Features
- Single-stage design with valve plate
- Materials: grey cast iron with stainless steel impeller, stainless steel 304 or stainless steel 316L for corrosive media
- As a compact monoblock pump or as a lantern-mounted version for a standard motor
- Single mechanical seal; operating liquid up to 80 °C
