Edwards SHR2400 – two-stage liquid ring vacuum pump
The SHR2400 delivers 608.4 m³/h at 50 Hz and 698.4 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, and vapours and entrained liquid are tolerated.Features
- Two-stage design with valve plates
- Bareshaft version for drive via coupling or belt
- Materials: grey cast iron, grey cast iron with stainless steel impellers or stainless steel 316
- Mechanical seals flushed via internal channels – only operating liquid required
Typical applications
Edwards uses the SHR and EHR pumps, among other things, in systems for condenser air extraction in power stations.Versions of the Edwards SHR2400
