The ELRI series, single-stage, total recovery vacuum pumps are proven technology and intelligence in a cleverly engineered package. Built to last, the reliability and low maintenance of these pumps offer the best solution when it comes to pumping wet gases or particulates.
The ergonomically designed IP 54 rated canopy with a small footprint is dust and splash proof with noise containment up to 69 dB.
The first VSD motor with set point control maintains and matches required vacuum levels. The second VSD for the water circulation pump optimises water flow and maintains stable vacuum.
The internal injection channels and mechanical seals provide a stable sealing arrangement. Stainless steel impellers and end plates are supplied as standard and the integrated non-return valve protects against back flow.
The anti-cavitation algorithm prevents the ELRi from operating in areas of cavitation, which increases the pump lifetime and reduces maintenance costs. The anti- seizure algorithm automatically turns off the pump for a few seconds after long periods of inactivity.
Water spray from the integrated spray nozzles cools and condenses the inlet gas and vapour from the process. This helps reduce energy consumption and increases impeller life.
Remote connectivity via AirLogic® controller and ICON box connectivity makes it easy to identify service requirements and plug gaps.
