e-HM, P, S, N Series

Summary

Product Identification

The product is the Lowara e-HM™ series pump, designed for water transfer and boosting applications in residential and multi-story buildings (up to 10 floors).

General Features

The e-HM™ series offers:

• Best-in-class efficiency with state-of-the-art hydraulics and IE3 motors for low operating costs.
• Long service life due to thick sheet metal casing, high-quality bearings, and stainless steel construction.
• Quiet operation achieved through high-efficiency hydraulics, motor, and thick sheet metal pump body.
• Reduced energy consumption with variable speed models that adapt to demand, significantly reducing power usage compared to fixed-speed pumps.
• Elimination of water hammer in speed-controlled systems by slowly stopping the pump.
• Stable water temperature in constant pressure systems, delivering fresh cold water on demand.
• Compact solutions with variable speed pumps, eliminating the need for bulky pressure tanks.

Available configurations include:

• e-HM bare pump
• e-HM pump with pressure switch and pressure tank
• e-HM pump with Genyo
• e-HM pump with Teknospeed
• e-HM residential boosters (2 pumps)

Operating Limits

The hydraulic performance tables for e-HM...P models at 50 Hz, single-phase, 220-240 V are provided, showing various pump types (e.g., 1HM03, 3HM05, 5HM04, 10HM02). These tables detail:

• Delivery (Q) in l/min and m³/h
• Total Head (H) in Metres of Column of Water
• Nominal Power (PN) in kW
• Input Power (P1) in kW
• Input Current (I) in A

Performance data complies with ISO 9906:2012 - Grade 3B. See the official PDF for exact tabulated values.

Electrical

• Equipped with IE3 motors for optimal efficiency.
• The e-HM...P models listed in the performance tables operate on single-phase 220-240 V.
• GENYO electronic controls are available in 8A and 16A versions.
