SMB Smart Variable Speed Booster Set

Lowara : Booster Pump Sets :

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
  • Certified for drinking water use (WRAS, ACS and D.M.174)
  • 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
  • VME series: vertical multistage, monolithic 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.


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.
