Lowara 3HME07S 0.75kW Variable Speed Smart Pressure Pump with 8L Pressure Tank (Max 85LPM/760kPa)

In every sector, from construction and industry to agriculture and building services the need for intelligent, compact and high-efficiency pumping systems is constantly growing. That’s why Lowara has developed the e-HME series: an integrated intelligent pumping system with electronically driven, permanent magnet motor (IE5 efficiency level). The integrated control system, combined with the high performance, power and efficiency from the motor and hydraulics, guarantees impressively low operating costs. You also benefit from flexibility, precision and its ultra-compact size.

• IES2 drive with permanent magnet motor for top efficiency
• More compact than the fixed-speed version, meeting the same duty points with precision and consistency
• Thick stainless steel casing, high-quality bearings, and stainless steel inner components minimize noise and guarantee long service life
• Certified for drinking water use (WRAS and ACS)
• Options include AISI 304 or 316 pump body and inner components, electropolished and passivated, and mechanical seal or O-rings

APPLICATIONS

• Water supply systems in residential buildings
• Air conditioning
• Water treatment plants
• Industrial installations

SAVINGS

The electronics and permanent magnet motor are highly efficient and minimize power losses while transferring maximum energy to the hydraulic parts of the pump. The refined control system with integrated microprocessor adjusts the motor speed, matching the required operating point of the pump or system requirements. This reduces demand on electricity according to the required working conditions. This creates economies, especially in systems where pump demand varies over time.

FLEXIBILITY

The compact size, low loss and increased control make the e-HM Smart series a good choice in applications and systems where fixed speed pumps are commonly used. The e-HM Smart series is easy to integrate in control and regulation loops thanks to the wide availability of compatible communication protocols, including analog and digital inputs. The pump is supplied with a pressure sensor

Ease of use and commissioning

e-HM Smart has an intuitive interface that guides the user through the installation, and a practical area to assist with connections. The control system is integrated and no additional external electrical panel is required.
