The leakage is visible where the screws are mounted on the base plate. As a result, no leakage will be detected. Under normal conditions, the leaking liquid will evaporate. The time required for this depends on the operating conditions, that is, every time the operating conditions change, a new run-in period will be started. When the pump is started for the first time, or when the shaft seal has been replaced, a certain run-in period is required before the leakage is reduced to an acceptable level. A slight leakage from the shaft seal of up to 10 ml per day or 8-10 drops per hour may occur. The shaft seal faces are lubricated by the pumped liquid. It is important to understand that, as Grundfos explains in the Scala manual, the main pump shaft is lubricated by the 'pumped liquid' - in our case, water.

If the pressure drops below the desired level, SCALA2 boosts its operation immediately to compensate for the loss of pressure. SCALA2 features a built-in sensor, which constantly measures the discharge pressure. Thanks to a water-cooled motor, SCALA2 even offers one of the lowest noise levels of any booster on the market. It packs pump, motor, tank, sensor, drive and non-return valve into one compact unit.Īnd with its intelligent pump control, SCALA2 automatically adjusts performance to both inlet pressure and water consumption in the home. SCALA2 is a fully integrated water booster pump providing perfect water pressure in all taps at all times – even with multiple taps and showers running at the same time. The SCALA2 is an advanced single-line jet-pump design that can pump from a depth of 8 metres (26 feet) of vertical lift. More Scala pump featuresĪn important feature noted by the company that protects the pump is that its design includes 'dry-running' protection. Installing a rubber mat below the pump base reduces its already quiet sound level by reducing transfer of vibration to the building - a step we took that we found successful. The Scala pump can be set to detect regular cyclic running for fixed 'on-cycles' that are characteristic of a plumbing leak (40 times can be set to trigger a shut-down).The Scala can also be set to shut itself down in the event of long running (30 minutes of non-stop operation).It can re-program itself to the available water supply to protect against running dry.The Scala 2 pump can detect a water leak in the building.The Scala2 factory default settings will leave the pump working just fine for most situations, but the Scala from Grundfos also has some sophisticated control options that can be turned on by your installer. Scala 2 Water Pump Factory Settings & Features The pump and its controls are simple to operate but it's also sophisticated, providing a number of other adjustments and settings such as its ability to automatically lower the water pressure setpoint if it cannot reach the pressure level set by the user, and its ability to sense and respond to a building plumbing water leak. This water pressure booster pump provides an easily adjusted output pressure that the pump will then maintain even when more water is being run in the building. It's quiet, easy to install, and maintains consistent pressure in all taps at all times. It is designed for perfect pressure inside the home. Is an integrated, self-priming, compact water booster pump.
