Edwards LR1D0260 – single-stage liquid ring vacuum pump
The LR1D0260 typically delivers up to 168.5 m³/h at 50 Hz and 208 m³/h at 60 Hz. 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
- As a compact monoblock motor pump (60 Hz) or as a lantern-mounted version for a standard motor
- Materials from grey cast iron to stainless steel 316 for corrosive media
- Mechanical seals flushed via internal channels – only operating liquid required
