Full Description

Product overview

The Grundfos Scala2 3-45 Model2 is a fully integrated variable speed booster pump. All components — pump, motor, inverter drive, pressure and flow sensors, integrated tank, and non-return valves — are built into a single compact unit. Installation is a three-step process: connect the pipes, prime, and plug in.

The intelligent speed controller continuously adjusts pump speed to match household demand, maintaining constant pressure at every outlet even when multiple taps and showers run simultaneously. The water-cooled permanent magnet motor delivers 47 dB(A) typical noise — one of the quietest domestic booster pumps available. The Model2 is 3 dB(A) quieter than the original Scala2.

The Scala2 cannot connect directly to the mains — it must draw from a break tank, cold water storage cistern, or other below-pump water source. It is self-priming to 8 metres. Suitable for horizontal or vertical installation, indoors or outdoors. Backed by a 2-year Grundfos warranty.

Key features

Intelligent variable speed

Continuously adjusts speed to match demand — constant pressure at every tap and shower, even with multiple outlets open simultaneously.

47 dB(A) — ultra quiet

Water-cooled permanent magnet motor. Model2 is 3 dB(A) quieter than the original Scala2. 53 dB(A) max at full load.

Fully integrated all-in-one

Pump, motor, inverter, sensors, integrated tank, and non-return valves all in one unit. No additional components required.

Flexible installation

Horizontal or vertical, indoors or outdoors. Compact footprint suits utility rooms, garages, cupboards, and outdoor enclosures.

Self-priming to 8m

Self-primes from a water source up to 8 metres below the pump in under 5 minutes. Suitable for break tanks, wells, and boreholes.

Dry-run and auto-reset protection

Stops automatically on dry running, overtemperature, or overload. Auto-restarts every 5 minutes up to 8 times, then every 24 hours.

3-step installation

Connect the pipes, prime the pump, plug in. The pump configures itself on first run — no specialist setup required.

Integrated pressure tank

Built-in pressure tank reduces pump starts on small draw-offs, reducing wear and extending service life.

2-year Grundfos warranty

2-year manufacturer warranty when purchased from Anglian Pumping Services.

Typical applications

Break tank systems

Draws from a cold water storage cistern or break tank — the ideal configuration for the Scala2.

Boreholes and wells

Self-priming to 8m — draws from a borehole, well, or underground tank without separate priming equipment.

Whole-house pressure boosting

Consistent pressure throughout the property — taps, showers, and appliances running simultaneously.

Electric and mixer showers

Consistent pressure to showers and thermostatic valves even during simultaneous use.

Combination boilers

Ensures adequate incoming pressure for combi boiler hot water and heating performance.

Outdoor installations

One of the few domestic booster pumps rated for outdoor use — suitable for outbuildings, plant rooms, and sheltered external locations.

Which should I choose?
Scala2 Model2 — the better choice when outdoor installation is needed, or when a break tank / borehole is already in place and installation orientation flexibility matters. No WiFi.
Esybox Mini 3 — higher flow (80 vs 70 l/min), higher head (55 vs 45m), higher max working pressure (5.5 vs ~4.5 bar), WiFi and voice control, longer 3-year warranty — and cheaper at £369 vs £422.48 + VAT. Indoor installation only.

Frequently asked questions

How much does it cost and how is it delivered?

£422.48 + VAT (£506.98 inc VAT). Standard delivery is free, including next working day when ordered before 12 noon on a working day. In stock and ready to dispatch.

Can it connect directly to the mains?

No — the Scala2 cannot connect directly to the mains supply. It must draw from a cold water storage cistern, break tank, or other below-pump water source. If you need a direct mains connection, consider the WaterBoost WB-Compact 3.0 or WB-Compact 4.5 instead.

What is the difference between this and the DAB Esybox Mini 3?

Both require a break tank and cannot connect to the mains directly. The Scala2 wins on installation flexibility — it can be installed horizontally or vertically, and indoors or outdoors. The Esybox Mini 3 wins on performance and value — higher flow (80 vs 70 l/min), higher head (55 vs 45m), higher max pressure (5.5 vs ~4.5 bar), WiFi and voice control (DConnect app, Google Home, Alexa), a longer 3-year warranty, and a lower price (£369 vs £422.48 + VAT).

What is the difference between the 93013254 and the 98562865?

Both are the Grundfos Scala2 3-45 Model2 — same pump, same specs, same price. The SKU difference reflects regional or supply chain product codes. If you’re unsure which to order, contact us and we’ll confirm which is in stock.

Can it be installed outside?

Yes — unlike most domestic booster pumps, the Scala2 is rated for outdoor installation as well as indoor. It can also be mounted horizontally or vertically, making it one of the most flexible booster pumps available for awkward or constrained spaces.

Is it suitable for use with a borehole or well?

Yes — the Scala2 is self-priming to 8 metres and can draw from a borehole, well, underground tank, or break tank. It primes from a source up to 8m below in under 5 minutes (provided it is filled with water first), making it well suited to rural properties with private water supplies.

What happens if the pump runs dry?

The Scala2 stops automatically on dry running, water shortage, excessive temperature, blocked pump, or overload — preventing motor burnout. It then attempts to restart every 5 minutes, up to 8 times, before switching to a 24-hour retry cycle. The auto-reset function can be deactivated.

Does it have WiFi?

No — the Scala2 operates as a standalone unit with no WiFi. If WiFi monitoring, remote control, or voice control are important, consider the DAB Esybox Mini 3.

What warranty is included?

2 years manufacturer warranty from Grundfos when purchased from Anglian Pumping Services.
