Large Capacity Liquid Ring Vacuum Pump (904S)

The Large Capacity Liquid Ring Vacuum Pump (904S) is engineered for demanding industrial environments requiring both vacuum and compression in a single unit. Upgraded from the 904 model, this pump features an improved variable port design for enhanced efficiency and a wider operating range. Constructed from 316L stainless steel, it offers excellent corrosion resistance and can be equipped with various mechanical seals. Key features include a patented gas scavenging system for superior performance at high vacuum levels, conical porting for optimized load distribution, and a self-priming design that may eliminate the need for a booster pump. Typical applications include chemical processing, paper manufacturing, mining, and geothermal power generation, especially where reliable compression of corrosive gases is essential.
