Flowserve SIHI vacuum systems have proven their worth in daily industrial operation for more than 30 years. This know-how enables our engineers to respond precisely to customers´ specific needs. All our plants are of modular design. The basic module is the vacuum pump complete with driver, service liquid cooler and liquid separator. Depending on the volumetric flow rates and suction pressures required, this basic module is augmented by e.g. a gas ejector module, a vapour ejector combination with downstream condenser, or a lobular pump module.
