Featuring Bluetooth connectivity for real-time monitoring and advanced protections against dry running, cycling, and overheating, it ensures reliable, efficient residential water pressure boosting and groundwater intake. Its smart design lifts water from depths up to 26 feet quickly, making it a must-have for modern homes seeking hassle-free, durable water pressure solutions. ## Description 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. In city water or well water applications, use a PRLV-30, Pressure Reducing Limit Valve on the suction side of the pump to 30 PSI to prevent inbound water from exceeding the 43 PSI max inlet pressure. 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 Note: 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. ## Features - 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. - Plumbing: Pressure Boosting - Residential groundwater intake - Residential water pressure boosting - Residential rainwater harvesting ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NQL24L9 | | Best Sellers Rank | #160,626 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #157 in Power Water Pumps | | Brand Name | Grundfos | | Color | Gray | | Customer Reviews | 3.8 3.8 out of 5 stars (77) | | Flow Rate | 15.8 Gallons Per Minute | | Horsepower | 1 Horsepower | | Item Dimensions L x W x H | 15.9"L x 7.6"W x 11.9"H | | Item Weight | 26.5 Pounds | | Manufacturer | grundfos | | Manufacturer Part Number | 99631742 | | Manufacturer Warranty Description | Grundfos pumps manufacturer warranty "24 months from Startup or 30 months from date code" | | Material Type | Stainless Steel | | Maximum Lifting Height | 26 Feet | | Model Number | 99631742 | | Power Source | Electric | | Product Style | Modern | | Specific Uses For Product | Plumbing: Pressure Boosting; Residential groundwater intake; Residential water pressure boosting; Residential rainwater harvesting | | Unit Count | 1.0 Ounce | | Voltage | 115 Volts (AC) | ## Product Details - **Brand:** Grundfos - **Color:** Gray - **Item Weight:** 26.5 Pounds - **Material:** Stainless Steel - **Maximum Flow Rate:** 15.8 Gallons Per Minute - **Maximum Lifting Height:** 26 Feet - **Power Source:** Electric - **Product Dimensions:** 15.9"L x 7.6"W x 11.9"H - **Style:** Modern - **Voltage:** 115 Volts (AC) ## Images ![SCALA1 3-45 Booster Pump - Image 1](https://m.media-amazon.com/images/I/618aJI8SxvL.jpg) ## Questions & Answers **Q: What is the voltage on the scala1-3-45 is it 120v? 230v?** A: The voltage on THIS scala 1-3-45 is 120v.
