Purified Water Distribution Loop – ST-LPW35 Series moves purified water from storage to each point of use and returns it through a closed loop. Correct pump sizing and pressure-loss calculation maintain circulation at distant outlets and reduce stagnant sections.
The modular skid monitors temperature, pressure, flow and conductivity. Sanitary pipework, sampling points and a selected sanitization method support routine operation and validation.
PROCESS AND CONTROL
How this system solves the water-supply task
Sanitary construction
316L pipework, sanitary fittings and controlled welding reduce crevices and simplify inspection.
Measured distribution
Online temperature, pressure, flow and conductivity help operators detect changes before they affect remote outlets.
APPLICATION ENVIRONMENTS
Where this configuration is used
Pharmaceutical purified-water loops
Distributes purified water between generation, storage and production points.
Water-for-injection distribution
Supports a compatible hot or sanitizable WFI loop after project-specific design review.
Clean utility piping
The hygienic layout can be engineered for compatible pure-steam or clean compressed-air distribution projects.
SYSTEM SELECTION
Design around the distribution route
Outlet plan
Set pump duty from the pipe route, pressure losses and simultaneous draws so circulation reaches the remote use points.
Sanitization access
Coordinate the sanitary connections, sampling positions and thermal-sanitization arrangement with the storage plant and all connected equipment.
