Product Overview

The SCALA1 TWIN 3-45 (115V) pump is currently out of stock until late March, 2024. As an alternative, check out the DAB ESYBOX MINI 3 Double.
Note: The primary difference between the two pumps is that the ESYBOX MINI Double offers a variable speed drive which provides constant pressure, and you can set the pressure where you want it, where the SCALA1 TWIN 3-45 is a single speed pump that does not allow for pressure adjustments. Both are "on demand" pumps.

Note: Fixed Shipping Rate does not apply to Hawaii or Alaska.
Note 2: Comes in 3 separate boxes. Assembly required. See 2nd video (below) for assembly example, along with Quick Setup Guide (document link below).
Grundfos SCALA1 is an all-in-one pressure boosting unit with a high-efficiency motor and hydraulics with low noise operation for domestic water supply and also light commercial applications. Built-in Bluetooth communication gives you complete control over the pump using the Grundfos GO REMOTE, also for twin pump operation.
This means that installation and commissioning has never been easier. The Grundfos GO REMOTE app also lets you see alarm status and get easy pump diagnostics. You can create and email reports onsite and access hard-to-reach installations remotely from the app.
Built-in multi-pump/booster technology enables twin pump connection with joint pump control in either duty/assist or duty/standby mode.
Online configuration is done easily using the Grundfos GO REMOTE app, where you can also adjust the alternation setup.
SCALA1 can connect via Bluetooth.
(A small, 2 - 4 gallon pressure tank is recommended in applications where a water heater is in place to allow for thermal expansion in the line. A small pressure tank will also prevent cycling when a leak is present in the piping, extending the life of the pump.)
The SCALA1 is a self-priming, multistage pump, that incorporates all the components of a pressure booster into a compact composite enclosure.

As it is self-priming, the SCALA1 can pump water from a level below the pump. Provided it is filled with water, the pump can lift water from a depth of 26 feet in less than 5 minutes. This facilitates easy installation and start-up of the pump and provides more reliable water supply in installations where there is a risk of dry running and leakages in suction hose or pipes.

SCALA1 can communicate with Grundfos GO app via built in Bluetooth, which enables detailed pump monitoring and high customization options, making this pump a good fit for every application.

SCALA1 incorporates advanced protection features such as:

  • Dry running protection that will automatically stop the pump in case of water shortage
  • Cycling protection which will prevent pump starting frequently in case of minor leakages in installation
  • Max runtime protection can stop the pump after a desired period of continuous operation, preventing potential damage due flooding in case of pipe breakages.

The pump has a built-in motor protection that will stop the pump if exposed to excessive temperature due to high ambient temperature, in case of seizure or overload, thus preventing a motor burnout.

With Grundfos GO, you can easily setup SCALA1 as a Twin booster system, operating as duty/stand by as well as duty/assist. It is also possible to add external input control and schedule a pump operation via calendar function.

SCALA1 requires no maintenance, but it is recommended to keep the pump clean. Check the non-return valves, and keep the ventilation holes free of dust.

Suitable for:
  • Plumbing: Pressure Boosting
  • Residential groundwater intake
  • Residential water pressure boosting
  • Residential rainwater harvesting

The SCALA1 is a fully integrated, all-in-one, self-priming, compact waterworks designed for pressure boosting in domestic and light-commercial applications, such as garden irrigation or pressure boosting to one and two family houses and apartments.
