ELRi series (Edwards)
Edwards ELRi single stage liquid ring vacuum pumps are proven technology in a sophisticated package. ELRi pumps are built to last, offering reliability with short maintenance intervals. When it comes to pumping wet gases or particles, these pumps offer the best solution.
The ELRi pumps are suitable for a range of applications across different industries including:
Compact Canopy Certified IP
The compactly designed, IP 54-certified housing with a small footprint offers dust and splash-proof operation with noise insulation of up to 69 dB.
Two built-in VFD motors
The first VSD motor offers setpoint control to maintain and adjust the required vacuum levels. The second VSD is used to optimize the water cycle and maintain a stable vacuum.
The ELRi is available in two variants – standard variant with a plate heat exchanger and heavy-duty variant with a shell and tube heat exchanger for more corrosive and dirty applications
Innovative design with a robust internal structure
The internal injection channels and mechanical seals ensure a stable sealing arrangement. Stainless steel impellers and end plates are supplied as standard and the integral check valve prevents back flow.
High protection through patented algorithms
The anti-cavitation algorithm prevents the ELRi from operating under cavitation conditions, increasing pump life and reducing maintenance costs. The anti-seize algorithm automatically turns the pump on for a few seconds after prolonged periods of inactivity.
Ideal for wet applications
The water mist from the integrated spray nozzles cools and supports the condensation of the inflowing process gas and steam. With the AirLogic® controller you can monitor and control several pumps at the same time. The ICON control provides you with an overview of the operating status of the pump, setpoint control and all other pump data.
