Submersible pump SCALA1 3-25 1x230V 50Hz, BLUETOOTH communication 99530403

Compact water supply system for comfortable water supply

The Grundfos SCALA1 3-25 booster pump is a fully integrated solution designed to increase water pressure and provide a stable supply in single-family homes and small commercial properties. The unit combines a pump, control and protection in one compact housing, making installation easier and saving space. SCALA1 is ideal for both supplying installations from shallow wells (up to 8m deep) and for increasing water pressure from the water supply network or intermediate tanks.

Intelligent functions for comfort and safety

SCALA1 stands out from traditional booster pumps thanks to its built-in Bluetooth module. This allows wireless communication with the Grundfos GO REMOTE mobile app, enabling remote control of the pump, monitoring its parameters and access to advanced configuration functions. The app informs about any failures and allows for quick diagnosis of problems. In addition, the pump is equipped with a number of protections that protect it from damage and ensure long-term reliability.

Advanced protection and efficiency

The design of the SCALA1 pump has been designed with durability and reliability in mind. It has a dry-running protection that automatically stops the pump in the event of a water shortage, protecting the motor from damage. The cyclic on/off protection prevents frequent pump starts and stops with minor leaks in the installation. In addition, the pump has a maximum operating time function that switches off the device after a specified period of continuous operation, minimizing the risk of failure due to overheating or other irregularities. The water-cooled motor ensures quiet operation of the device and high energy efficiency. The motor power is 0.55 kW (P1) with a power output of 0.36 kW (P2). The maximum pump capacity is 5.4 m³/h with a maximum head of 25 meters. The pump also has RS-485 communication interfaces and 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals and PT100 / PT1000 / PTC, which allows integration with building automation systems.
