The NEW e-LNE and e-LNT in-line pumps

×High Efficiency

New designed high efficiency hydraulics, with MEI values well above the ErP2015 level and IE3 motors set the basis for very low operation costs. Hydraulic efficiency of MEI 0.6 exceeds the ErP compliance level of MEI 0.4.  IE3 motors are fitted as standard, and IE4 motors can be supplied along with our Hydrovar variable speed drives.

×Long service life & easy maintenance

Robust design, different bearing frame sizes and stainless steel replaceable wear rings ensure a long service life. The e-LNE & e-LNT series is also designed for easy maintenance and all service points are easy reachable to reduce downtime.

×Adapt to needs

In many applications the need for water is always varying. By equipping these In-line pumps with a Hydrovar pump controller, the duty is always exactly where it should be. And it pays off: reducing the speed by 50% reduces the power consumption by 85%.

×Exactly the right configuration

With material options spanning from cast iron body in GG25 cast iron, stainless steel, Bronze impellers with choice of mechanical seal options the e-LNE / e-LNT is the right solution for 1000’s of liquids.

×Hot or cold

The standard e-LNE / e-LNT can handle liquid temperatures from -25°C up to +120°C and the extended temperature version up to +140°C. The Lowara e-LNE Series can be used for the following CBS applications:

HVAC

  • Liquid transfer in heating systems.
  • Liquid transfer in air-conditioning systems.
  • Liquid transfer in ventilation systems.

Water Supply

  • Pressure boosting in commercial buildings.
  • Irrigation systems.
  • Water transfer for green houses.

The new Lowara e-LNE and e-LNT series in-line pumps for heating and chiller systems are highly energy-efficient, deliver greater operational cost savings, and will provide improved hydraulic coverage that can serve a broader range of applications.

Offering a range of single impeller centrifugal pumps with inline suction and discharge delivery flanges, the e-LNE and e-LNT have a back pull-out design which allows the impeller, adapter and motor be extracted without disconnecting the pump body from the piping system.

Hydraulic efficiency of MEI 0.6 exceeds the ErP compliance level of MEI 0.4. IE3 motors are fitted as standard, and IE4 motors can be supplied along with our Hydrovar variable speed drives.

Ultimately the e-LNE and e-LNT series will offer outstanding hydraulic coverage, with more than 22 additional models across the range.
