Grundfos Scala pumps are all-in-one integrated water booster pumps that improve water pressure, increase water flow, and ensure a constant supply of water to households, gardens, and light commercial applications. The Grundfos Scala series offers two unique models (Scala 1 and Scala 2) with distinct features and benefits, but both are compact, easy to install, and easy to operate. Grundfos has discontinued production of its Grundfos MQ series of pumps and is transitioning from the MQ series to the new and improved Grundfos Scala series. These Scala pumps come with the reliability and superior performance Grundfos is known for, while integrating new technologies like Bluetooth connectivity. Below you will learn more about water booster pumps, the Grundfos Scala series, and which model is the best choice for you.
What is the Grundfos Scala series?
The Grundfos Scala series is Grundfos’ latest version of all-in-one, self-priming pressure booster pumps. There are two models in the Scala series: Scala 1 and Scala 2. Both are suitable for domestic and light commercial applications and are easy to install and operate. Scala pumps are recommended for residential water pressure boosting, pressure boosting of water from roof tanks, break tanks, and ground tanks, increasing water supply from shallow wells, irrigation, and water transfer. Below, we’ll highlight the features of Scala 1 and Scala 2 and break down their key differences so you can decide which pump is the best choice for you!
Grundfos Scala 1 booster pump
The Grundfos Scala 1 is a self-priming, multi-stage, Bluetooth enabled booster pump suitable for both domestic and commercial applications. Scala 1 delivers water on demand and is constructed with corrosion resistant materials to ensure longevity and trouble-free operation. Provided it is filled with water, the pump can lift water from a depth of 26 feet in less than five minutes. Plus, it’s quiet and discreet with a noise level less than 55 dBA (A-weighted decibels) - about as loud as an average coffee maker.
Perhaps the most unique feature of Scala 1 is its communication with the Grundfos GO Remote app via built-in Bluetooth technology. This enables ample customization and detailed monitoring, making Scala 1 an excellent choice for countless applications. Through the app on your smartphone, you can shut the pump down, receive alerts when the pump runs dry or runs too long, receive pump diagnostics and statuses, and personalize many other settings and features.
Lastly, Scala 1 is twin booster enabled, which permits a simple twin pump set-up for larger commercial needs. Whether you use it to boost the water pressure in your home, irrigate your garden, pump water from a storage tank, or commercially, the Scala 1 pump can be adapted to your preferences.
Grundfos Scala 2 booster pump
The Grundfos Scala 2 is a self-priming, compact booster pump equipped with integrated speed control for pressure boosting in domestic applications. It can lift water from a depth of 26 feet in less than five minutes, allows for perfect water pressure, and is energy efficient. Plus, the pump is small enough to fit inside a kitchen cabinet and has a low noise level of 47 dBA, which is as quiet as a modern dishwasher.
Although, integrated speed control is undoubtedly Scala 2’s standout feature. Integrated speed control means the pump performance will adjust to water demand, enabling the ability to keep perfect pressure in all of your home’s taps regardless of how many are being used at a given time. The integrated speed control sensor measures pressure discharged from the pump. If there is a difference between the pressure output and the desired pressure level set by the homeowner, pump speed will increase or decrease to reach the preset levels and maintain constant pressure in the system.
Currently, a smartphone connection is unavailable for the Scala 2, so it cannot be controlled via the Grundfos GO Remote app. However, plans are in place to equip future Scala 2 models with the necessary Bluetooth technology.
Was the Grundfos Scala 2 recalled?
Yes, the Grundfos Scala 2 was recalled in 2019 because of a leak failure. Grundfos recalled models with PC codes 1603 and 1901, which means the models in question were manufactured the third week of 2016 and the first week of 2019, respectively. Not all models were failing, so if you had already installed the pump at the time of the recall, Grundfos advised to leave it in place for observation. Newer models have since been reconfigured to eliminate the problem.

Will the Grundfos Scala series replace the Grundfos MQ series?
Yes, the Grundfos Scala 1 series will replace the Grundfos MQ series. The MQ pumps have been discontinued by Grundfos, and the Scala 1 pumps are intended to take their place as a compatible alternative. The Grundfos Scala series boasts the same impressive technical specifications of the Grundfos MQ series, but with improved engineering and technologies like Bluetooth connectivity.
The Grundfos Scala series is designed to be a direct replacement for those who were previously familiar with the Grundfos MQ line of water pumps. For example, the MQ3-45 (115V) can be directly replaced by the Scala1 3-45-1. The Scala 1 can tackle both domestic and commercial applications with the same efficiency and reliability, but with the added benefit of pump monitoring and customization via Bluetooth integration. Those who formerly utilized the MQ series of pumps and are seeking replacement can easily transition to the Scala series without fear of reduced performance or interruption in efficiency.
How long is the Grundfos Scala warranty?
Grundfos Scala pumps are covered by warranty for 24 months from the date of installation or 30 months from the date of manufacture. The Grundfos Scala pump warranty covers any potential manufacturer defects and pump failures. It does not cover for damage or wear caused by abnormal operating conditions, misuse, or accidents.
What are water booster pumps?
Water booster pumps are centrifugal pumps that improve low water pressure and increase water flow. Water booster pumps also provide pressure to move water from a storage tank, throughout a home, or through a commercial facility.
How do water booster pumps work?
Water booster pumps work similar to fans. Akin to how a fan’s blades create a gust of air, a water booster pump’s rotating impeller draws water in and then pushes it out with increased force, consequently raising water pressure. Most are centrifugal pumps that take water from a source and move it through an impeller or multiple impellers to increase water pressure. The high-pressure water then moves through an outlet and flows to your desired destination. Typically, a water booster pump is installed where the main water line enters your home, so water pressure is improved in every tap and appliance.
What are water booster pumps used for?
Water booster pumps are used to improve water pressure, increase water flow, and to transport water. With both residential and professional applications, water booster pumps are versatile tools. Whether you would like to increase the water pressure in your shower, to enhance the efficiency of a well, or to provide water for a multi-story hotel or apartment complex, a water booster pump can provide the solution. Below are common uses of water booster pumps for homes, for wells, and for professional and industrial purposes.
Water booster pumps for your home
- Water booster pumps can boost water pressure throughout your home and provide higher pressure in your showers, sinks, and appliances.
- Water booster pumps can repressurize water from a storage tank and send it to a faucet or throughout your home.
- If you have a rainwater harvesting system, a water booster pump can move water from a rain barrel or storage tank to your irrigation system, home, or other intended point of use.
Water booster pumps for a well
- If you have a low recovery well that doesn’t produce enough water to keep up with household demand, a water booster pump can pull water from the well’s storage tank to supply and pressurize the water in your home.
Water booster pumps for professional and industrial purposes
- Moving water through high-rise buildings or up-hill requires high pressure. Hotels and other high-rise buildings use water booster pumps to send water to the top stories.
- When a pond or reservoir is used for irrigation, water booster pumps move water from the source to the sprinkler heads.
- Water booster pumps increase water flow in water systems and in industrial equipment and facilities.
