Lowara SMB20 HME Booster Set
Lowara SMB20/A/15HME01S11/M2/UK booster set 1003100508
- Established 1975
- Trusted by thousands of customers
The Lowara SMB20/A/15HME01S11/M2/UK (1003100508) is a twin-pump variable-speed booster set from the Lowara SMB range, built with two 15HME01S11 Lowara e-HM Smart (e-HME) horizontal multistage pumps, each with a 1.1 kW high-efficiency permanent-magnet motor and integrated e-SM drive, for a 1 × 230 V single-phase supply. It delivers up to 20.9 m of head and flows up to 58 m³/h (966.7 l/min) with all pumps running.
Each pump has its own e-SM drive, and the two pumps share the load, starting and stopping in cascade to hold a constant set pressure as demand changes. Supplied assembled on a base with ball valves and non-return valves on each pump, suction and delivery manifolds, pressure gauge and transmitters, and an IP55 control panel with dry-running protection.

FAQs
The SMB series is designed for water pressure boosting and transfer. It uses the latest technology to easily deliver water at the correct pressure and flow for residential and light commercial applications.
- Variable speed operation ensures smooth pressure control and quiet performance without water hammer
- IES2 and highest hydraulics efficiency save money and reduce lifecycle costs
- Pressure remains constant, despite frequent variations in water consumption
- Smart curves create compact design
- R version available with suction and delivery manifolds on same booster side for an even smaller footprint
- WRAS certified for drinking water use
- Communication via Modbus and BACnet with optional cards
Available with two and three pumps:
- e-HME series: horizontal multistage pumps
- e-SVE series: vertical multistage, stainless steel pumps
Plug and pump booster set
The system is easy to commission and operate, thanks to friendly HMI with a preset package. The unit features stainless steel manifolds, vibration dampers, a non-return valve and two gate valves per pump. It’s rated at a C1 class level, the best in class against harmonic disturbance, so there’s no need for further EMC filters. It’s also suitable for harsh environments with an IP55 enclosure rate. Analog input 0-10V is available for external control. The system is designed to work in extreme conditions up to 40°C without derating.
Reliability
Get multipump control without an external control panel. SMB booster sets are equipped with one pressure transducer per pump through 4-20 mA signal. Operation is still possible, even when one or more pumps or sensors are unavailable.
Individual pump control
Each individual pump has the capability to take control. That means that the system will continue to operate as a booster system even if one or more of the pumps or sensors is unavailable. Compared to systems with only one control unit, the SMB series is an extremely reliable source of pressure.
One sensor — one pump
The SMB series includes one sensor per Smart Pump as standard, providing full redundancy and avoiding a unique failure point.
Safe operation
Each frequency drive comes with contacts for fault diagnostics and dry-run protection connections as standard. Each e-SM drive frequency converter features an automatic switch for thermal magnetic protection. The system incorporates cyclical exchange of pumps, temperature sensors in motors and drives, and error logs.

What is a water booster pump?
A water booster pump increases the pressure of an existing water supply to give stronger flow at taps, showers and appliances. It can be a small inline pump fitted to the incoming mains, or a larger pump and tank set that draws from a break tank to feed the whole house. Boosters do not create water – they raise the pressure of the water already coming in.
What is the difference between an inline booster and a tank-and-pump booster?
An inline booster connects straight onto the incoming mains and is limited to 12 litres per minute under UK water regulations – examples include the Salamander HomeBoost and WaterBoost WB-Compact. A tank-and-pump booster, such as the Grundfos Home Booster or DAB Esybox with Esytank, draws from a break tank and can deliver much higher flow rates for larger homes with multiple bathrooms.
What is a variable speed booster pump?
A variable speed booster uses an inverter to adjust pump speed in real time to match demand. It maintains constant pressure as outlets open and close, runs more quietly than a fixed-speed pump and typically saves up to 50 per cent of the energy a fixed-speed equivalent would use. The DAB Esybox, DAB Esybox Mini 3 and Grundfos Scala2 are common variable speed examples.
What are centrifugal pumps used for?
Centrifugal pumps use a rotating impeller to move liquids and are commonly used for water transfer, circulation and industrial processes.
How do I choose a centrifugal pump?
Compare the required flow rate, total head, liquid characteristics and electrical supply with each pump’s performance curve.
Are centrifugal pumps suitable for dirty water?
Some are designed for clean water only, while others handle solids or wastewater. Check the particular pump’s permitted liquid and solids specification.
What does a water booster pump do?
A water booster pump raises water pressure to help supply taps, showers and other outlets when the existing system cannot meet demand.
Can a booster pump connect directly to the water mains?
Not every booster can. Direct connection depends on the product design and applicable water regulations; some systems require a break tank.
How do I size a water booster pump?
Assess simultaneous flow demand, required outlet pressure, available inlet conditions and the pressure losses in the pipework.
