Grundfos CHI Commercial Pumps

CHI is a unique product combining stainless steel materials in all parts in contact with the pumped liquid with a compact design and an MLE motor. This makes CHI very suitable for industrial applications requiring a stainless steel product combined with the variable pump performance feature. CHI can operate in uncontrolled operating mode enabling pump performance control by an external signal. Alternatively, the pump can operate in controlled operating mode enabling e.g. a constant pressure to be established by means of the built-in PI-controller and a connected sensor. Other sensor types such as flow, temperature, differential temperature or differential pressure can also be connected.

CHI Pumps are designed for thin, clean, non-aggressive and non-explosive liquids without solid particles or fibers. The pumps are able to pump liquids such as demineralised water, softened water, cleaning solutions, light oils and other light chemicals. When pumping liquids with a density and/or viscosity higher than that of water, motors with correspondingly higher outputs must be used, if required. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are chloride content, pH value, temperature and content of solvents, oils, etc.
