Description
The Wilo-Atmos TERA-SCH axially split case pump provides a reliable water supply 365 days a year at low operating costs. The pump’s easy maintenance design and high efficiency across the entire characteristic curve ensure low-wearing and energy-efficient operation and contribute to a consistent water supply.
Applications
- To supply water in civil and industrial buildings.
- As pressure boosting pump to increase water pressure when needed (follow local rules).
-
Advantages
- Reliable continuous duty for an efficient drinking water supply over extensive piping networks – can be tailored to suit your exact requirements
- Reduced energy costs through high overall efficiency
- Simplified and shorter alignment process thanks to tolerant coupling and motor adjusting device
- Increased operational reliability thanks to quiet-running hydraulics with lower vibrations and reduced noise level
- Reduced cavitation tendency through optimised NPSH-performances
- Lower space requirements due to compact design
- Also available as certified drinking water version
- Optionally with Ceram CT coating – for an efficiency increase of up to 3%
- Standard volume flow of up to 4500 m³/h
