ANDRITZ non-self-priming volute casing centrifugal pumps from the ES series are extremely compact units which require very little space. They are particularly suitable for all those applications where space is at a premium, i.e. in crate and bottle washing machines, in air conditioning, refrigeration and heating systems, in surface finishing, dust collection, water treatment, water supply and irrigation plant, also in industrial washing machines. The pumps are designed to handle clean or slightly contaminated media over a temperature range from -20 to +140°C. Even corrosive media can be handled provided pump materials and mechanical seals have been selected accordingly. A special vortex or two-channel impeller is available for certain pump models.
