Product Description
Grundfos SCALA2 3-45 Water Pressure Booster Pump (Part No. 98566118)
Intelligent Pump Control for Perfect, Constant Water Pressure Across All Taps
The Grundfos SCALA2 3-45 is a fully integrated, compact, self-priming water booster system designed to deliver perfect water pressure in all taps at all times. Equipped with an advanced variable speed drive (inverter), the SCALA2 continuously monitors the discharge pressure. If the pressure drops due to multiple taps being opened simultaneously, the integrated controller immediately accelerates the motor to match the exact demand. This sophisticated all-in-one unit houses the pump, motor, tank, sensor, drive, and non-return valves within a single sleek enclosure, eliminating the need for bulky, multi-component traditional booster sets.
Key Features and Technical Advantages of the Grundfos SCALA2:
- Intelligent Inverter Technology: Automatically adjusts pump performance to maintain a stable, unvarying water pressure throughout the property, ensuring comfortable showers and efficient appliance operation even during peak usage.
- Ultra-Quiet Operation (~47 dB): Thanks to a state-of-the-art water-cooled permanent magnet motor, the SCALA2 eliminates the loud noise of standard air-cooled motor fans. It operates as quietly as a modern dishwasher, making it perfectly suitable for indoor installation.
- Comprehensive Built-In Protection: Features a robust electronic safety package, including dry-running protection (with automatic restart), motor overheating safeguards, voltage fluctuations protection, and an anti-cycling alarm that prevents the pump from running repeatedly if a micro-leak occurs in the plumbing system.
- Excellent Self-Priming Capability: Capable of lifting water from a depth of up to 8 meters in less than 5 minutes, making it highly versatile for pulling water from shallow wells, underground storage tanks, or boosting from low-pressure break tanks.
- User-Friendly Control Panel: The intuitive touch-button interface allows operators to easily set the desired discharge pressure at the push of a button, while clear LED indicator lights display operational status, pressure levels, and specific fault codes for effortless troubleshooting.
Primary Applications and Industries:
- Car Wash Systems & Technology: Ideal as a dedicated booster pump to stabilize and elevate water pressure feeding chemical dosing panels, water softener inlets, or reverse osmosis (RO) preprocessing units.
- Residential Water Supply: Boosting water pressure from city mains, break tanks, or clean rainwater harvesting reservoirs into single-family houses or light commercial buildings.
- Commercial Irrigation: Efficiently powering extensive lawn irrigation networks, greenhouse misting systems, and outdoor watering loops.
Frequently Asked Questions (FAQ)
Does the SCALA2 pump require a large external pressure tank?
No, it does not. Traditional pumps rely on massive pressure vessels to minimize motor cycling. The SCALA2 utilizes an internal, compact 0.16-liter diaphragm tank paired with an intelligent inverter drive that infinitely varies motor speed. This completely removes the requirement for a large external expansion vessel, freeing up substantial floor space.
Can this booster pump be safely installed outdoors?
Yes, the SCALA2 features a rugged, weather-resistant design certified to an IPX4D enclosure class. It can withstand splashing water and light outdoor elements. However, for winter operations, it must be thoroughly insulated or drained; water freezing inside the pump casing will cause non-warranty cracking and structural failure.
What is the purpose of the anti-cycling feature on the SCALA2?
The anti-cycling system protects the pump from unnecessary wear and thermal stress caused by small, hidden leaks in your piping (such as a dripping valve or a faulty toilet cistern flush). If the system detects that the pump triggers on and off in rapid succession without an actual user turning a faucet, it stops operation and fires a specific warning code to protect the internal components.
