Product Overview
Corrosive, chemically active municipal supply loops benefit from the resilient design of the Lowara 1HM12N05M. By utilizing high-grade AISI 316 stainless steel components throughout its fluid-contact areas, the unit ensures integrity when processing aggressive water types or industrial chemicals. Its compact, horizontal configuration makes it suitable for integration into tight machinery spaces where horizontal foot-mounting is required, providing a stable foundation for steady-state fluid movement in water treatment or temperature control applications.
Operational threshold limits are defined by a Max Head 68.8 m alongside a Max Flow 40 L/Min for this specific model configuration. The system draws 0.55 kW at 240v, managed by a two-pole motor design that maintains consistent speed for high-pressure delivery requirements. Performance curves verify that even under load, the hydraulics maintain stability across the operational window, supporting continuous usage cycles in professional water circulation systems.
Fluid dynamics are governed by a multistage arrangement that progressively increases pressure through each internal chamber. The AISI 316L stainless steel architecture of the rotating components minimizes hydraulic friction losses, promoting energy-efficient fluid acceleration from the suction port to the discharge nozzle. This internal design utilizes precision-engineered clearances to ensure minimal recirculation within the stages, which assists in maintaining high volumetric efficiency during sustained operation.
Housing the assembly is a TEFC electric motor that provides protection against ambient moisture and particulates to an IP55 standard. Mechanical sealing is handled by silicon carbide surfaces paired with EPDM elastomers to manage internal pressure stresses effectively. The unit is designed for direct mounting, using standard 25 mm inlet and outlet connections that facilitate fast installation into existing rigid piping networks, requiring only standard electrical termination for system integration.
Features:
- Silicon carbide mechanical seal surfaces for enhanced resistance
- TEFC electric motor housing with IP55 environmental protection
- AISI 316 stainless steel construction for chemical handling
- EPDM elastomer sealing components for fluid compatibility
- Two-pole motor operating at approximately 2900 rpm speed
- Certified for drinking water contact per international standards

Under challenging fluid exposure, what pump metallurgy and mechanical seal components resist attack?
Alloy construction throughout the 1HM12N05M employs AISI 316L stainless steel pump casing, diffusers, and closed impellers paired with mechanical face seals against corrosion.
How many kilowatts of electrical motor power and what operating voltage current feed run this pump?
Energizing the 1HM-12N-05M requires 220–240 V, 50 Hz, single-phase to power its 0.55 kW (0.75 HP) motor operating at 3.96 A.
Across multi-stage booster duties, what liquid operating temperature limits and pressure rating apply?
Operational pressure margins on the 1HM 12N 05M feature a maximum working pressure rating of 16 bar (PN 16) and liquid temperatures from -30°C to +120°C.
In tall plumbing risers, what peak dynamic elevation head is generated by this booster?
Overcoming elevation rises, the 1HM_12N_05M generates a peak dynamic head of approximately 68.8 m.
For liquid transfer duties, what water delivery flow capacity and outlet port diameter are built in?
Plumbing line integration with the 1HM12N05M employs Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, delivering a maximum fluid flow rate of approximately 40 L/Min.
