Centrifugal pump Atmos TERA-SCH series

waterwith electric motorstationary

Product overview
The Atmos TERA-SCH is an axially split-case pump designed for reliable 24/7 continuous operation and energy-efficient transport of large volume flows through extensive distribution networks. The pump is optimised for low-wear, quiet operation with reduced cavitation tendency and simplified maintenance.

Main benefits

• Reliable continuous duty for efficient drinking water supply across extensive piping networks, configurable to specific requirements
• Reduced energy costs through high overall efficiency
• Simplified and shorter alignment process thanks to optional tolerant coupling and motor adjustment device
• Quiet-running hydraulics with lower vibrations and reduced noise level for increased operational reliability
• Reduced cavitation tendency through optimised NPSH performance
• Lower space requirements due to compact design
• Available as certified drinking-water version
• Optional Ceram CT coating — can increase efficiency by up to 3%
• Standard volume flow up to 4,500 m³/h
