Edwards ELR1050i – outdated model
The ELR1050i is no longer part of the current Edwards range; Edwards names no successor in its current documents. In the Ehrler & Beck range, the Atlas Copco LRP 1000 VSD+ has the same nominal pumping speed, the same ultimate pressure and the same rated motor power as the ELR1050i. The ELRi is a single-stage liquid ring vacuum pump with total recovery of the service liquid, supplied as a ready-to-connect unit under a canopy with IP 54 protection. Two variable speed drives control the main motor and the circulation pump, and the controller maintains the vacuum set point. According to the brochure, the ELR1050i reaches a nominal pumping speed of 1050 m³/h (dry) and 1140 m³/h (saturated) at an ultimate pressure of 25 mbar absolute; the nominal installed motor power is 37 kW. The unit measures 1950 × 810 × 1020 mm (W × D × H) and has a dry weight of 900 kg. The technical data are taken from the Edwards brochure “ELRi Series – Intelligent Liquid Ring Vacuum Pumps” (publication 3602 700 0 01, 2020).Order numbers of the ELR1050i
