A complete system delivering market-leading efficiency

The Lowara Smart Pump range incorporates state-of-the-art technology to optimize performance, communicate with other building systems and help you achieve your goals. Choose pre-programmed packages for easy, cost-effective installation — and benefit from this system’s power, intelligence and performance.

Power: Best-in-class IE5 motor

Technical Specification IEC/TS 60034-30-2 introduces “ultra-premium” IE5 efficiency performance. It’s the top efficiency level for motors designed to not operate directly on-line. Each Lowara Smart Pump is equipped with a permanent magnet motor that meets this IE5 standard, providing efficiency well above a standard IE3 asynchronous motor.

Intelligence: Embedded motor drive

The smart, easy-to-set integrated drive can operate single, twin or multipump systems of up to three pumps, with no need for an external control panel or PLC. The drive matches performance to demand, reducing energy use. And it allows smart pumps to communicate with other building systems in real time, maximizing efficiency.

Performance: Robust pump range

A full line of single-phase pumps provides enhanced hydraulic performance for residential, light industrial and OEM applications. The Smart Pump range can easily handle extreme environments, from -20°C to 50°C, without derating performance.

Discover the great trio of efficiency

Lowara Smart Pumps combine three essential elements to ensure outstanding reliability, optimal savings and the shortest payback times. It’s not about individual components. It’s about a great team of three perfectly concerted elements:

Controls, safety features and monitoring tools

Available control modes include:

In addition to these regulation functions, the Smart Pump range also:

e-SV vertical multistage pump in stainless steel

The Lowara e-SV vertical multistage pump is a highly reliable and technologically advanced multipurpose pump. It’s capable of satisfying the needs of a wide variety of users and many different construction designs are available. The e-SV range feature models in eleven sizes with 1-3-5-10-15-22-33-46-66-92-125 m³/h nominal capacities. All pumps ≥ 1.5kW are equipped with IE3 standard motors.

Design features:

Balanced mechanical seal replaceable with out need for pump disassembling (for 10-15-22SV>=5,5kW, 33-46-66-92-125SV)
“O” Ring seat design to allow for simple outer sleeve dis-assembly
Floating for self alignment replaceable diffuser wear ring (PPS Glass filled technopolymer to withstand chemically corrosive, mechanically aggressive and high temperature liquids)
Reduced impeller axial thrust for longer standard motor bearing life (17,500h)
Hard Material Intermediate bush bearing (Tungsten Carbide/Silicon Carbide) to improve life and ability to withstand heavy duty applications, like boiler feeding
High temperature seal option (180°C max) with low NPSH design, high pressure design (up to 40 Bar), and passivated & electro-polished versions are available upon request.

Further unique features of the e-SV include the integration of performance diagnostic devices such as the i-Alert™ vibration monitor and Dry Run sensor. The i-Alert™ and the Dry Run sensor are available as an accessory for all models.
