e-SH

Summary

Product Identification

The Lowara e-SH Series consists of horizontal centrifugal electric pumps, designed according to EN 733. These are single-stage, end-suction electro-pumps with an axial flanged suction port, radial flanged discharge, and horizontal shaft.

Key features:

• Motor Efficiency: Equipped with IE3 efficiency motors.
• Ecodesign Compliance: ErP 2009/125/EC compliant, with a Minimum Efficiency Index (MEI) equal to or higher than 0.4.
• Design: Back pull-out design allows for impeller, bracket, and motor extraction without disconnecting the pump body from piping.
• Fluid Compatibility: Suitable for handling water as well as non-aggressive or moderately aggressive fluids.
• Available Constructions:
  • Extended shaft (ESHE)
  • Stub shaft (ESHS)
  • Frame mounted (ESHF)
  • Frame mounted with spacer coupling (ESHC)
  • Bare shaft pump (ESH)
