Single-phase hydrophore pump GRUNDFOS SCALA1 3-35, power 720 W, flow 3.72 m³/h, pump head 36 m, pressure 8 bar

Single-phase booster water pump GRUNDFOS SCALA1 3-35 has power of 720 W and a flow rate of 3.72 m³/h.

Head of 36 m and maximum pressure of 8 bar.

Pumps liquids from a level below itself. If filled with water, it can start pumping from a depth of 8 m in less than 5 minutes.

Installation is easy and ensures more reliable water supply in systems where there is a risk of dry running and leaks in suction hoses or pipes.

The pump can be controlled via the Grundfos GO app using built-in Bluetooth.

It can be configured as a twin system for pressure boosting.

It allows external input control and work scheduling through the calendar function.

It is recommended to check non-return valves and vent openings for contamination.

Protections:
 

• Dry-running protection, which automatically stops the pump when water is lacking
• Anti-cycling protection, which prevents the pump from frequent starts due to minor leaks in the system
• Maximum run-time protection stops the pump after a set period of continuous operation, preventing potential damage in case of flooding due to pipe rupture
• Built-in motor protection in case of exposure to high temperature from hot surroundings, blocking or overload
