## Long description

GRUNDFOS HYDROPHORUS SCALA1 3-35 230V is a compact, single-phase pressure boosting pump designed for domestic and light commercial water supply applications. The unit integrates a variable-speed motor and an electronic controller to maintain consistent water pressure across taps and showers. With a footprint suited to mechanical rooms and utility closets, this model combines pressure boosting, automatic start/stop and built-in dry-run protection in one preassembled package.
Advantages
The integrated controller ensures automatic operation and protection features without the need for external pressure switches or separate controllers. Variable-speed drive adapts pump output to demand, improving energy efficiency and reducing noise during low-flow periods. Its compact, factory-assembled construction simplifies installation and minimizes the space required. Built-in dry-run protection helps prevent damage when water supply is interrupted, and the sealed hydraulic section reduces maintenance frequency.
Suitable for
Boosting shower and tap pressure in single-family homes
Supplying small multi-outlet systems such as apartments or light commercial premises
Maintaining constant pressure for domestic water systems
Replacing older booster systems where compact automatic solutions are desired
Key specifications
Supply voltage: 230 V, single-phase
Variable-speed electronically controlled pump
Maximum head and flow performance in line with the 3-35 model range

How to use
Install the pump on a stable, level surface close to the water supply and electrical connection, following local electrical regulations. Connect inlet and outlet pipework using appropriate fittings and ensure system filters and check valves are in place. After making electrical connections to a 230 V single-phase supply, power the unit and allow the controller to detect system pressure. The pump will start automatically as demand increases and stop when pressure setpoints are reached. Refer to the manufacturer's installation manual for detailed commissioning steps and safety instructions.
Usage recommendations
Use in systems with clean water only and install a pre-filter if source water contains debris. Ensure electrical connections are performed by a qualified electrician and protect the unit from freezing. For optimal performance, follow recommended maintenance intervals and inspect seals and connections periodically.
