Liquid ring vacuum pump 904

lubricatedsingle-stagecompressor

The NASH 904 replaced the popular NASH CL pump in the 1980's, and can still be found operating in plants around the globe today. Capacities of the 904 pumps range upward from about 2,900 ACFM at vacuum. These durable pumps can handle excess liquid carryover without any difficulty, even if it arrives as massive slugs. 904 pumps are found in many industries including paper, chemical, and mining. Key Characteristics: Engineered for Demanding Environments 2in1: Pump & Compressor Reliable and Efficient Engineered for Demanding Industrial Environments The NASH 904 series offers medium to large capacity, single stage vacuum pumps that are ideally matched to demanding industrial applications and harsh environments. These durable pumps handle excess liquid carryover, including massive slugs, with difficulty and are engineered to withstand demanding industrial applications. Reliable and Efficient with conical porting and rotor configuration Patented in 1932, Nash’s conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. With constant innovation, Nash’s patented design features: Option for lobe purge to minimize damage from erosion in duties with solids present High liquid carryover tolerance Operates as a vacuum pump and compressor with a discharge pressure range of 30 psia (2.5 bar abs.) Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump - reducing cost and simplifying installation.
