Product Overview
Achieving precise pressure regulation across demanding industrial supply lines relies on the resilience of the Lowara 1HM25N11M. This horizontal multistage unit is engineered specifically for applications where purity and material longevity are essential, such as refined process water handling and fluid circulation. The structural composition ensures a high degree of stability within diverse operating environments, making it suitable for systems that require consistent fluid movement through restricted piping layouts.
Operational threshold limits are defined by a Max Head 146 m alongside a Max Flow 40 L/Min. This configuration is powered by a 1.1 kW / 240v motor which maintains efficiency during continuous cycle applications. The hydraulic performance adheres to international standards for rotating machinery, providing a predictable output curve that suits both commercial processing installations and domestic high-pressure water supply infrastructure requirements.
Fluid dynamics are governed by a robust AISI 316L stainless steel impeller arrangement which ensures efficient energy transfer and minimizes internal friction losses. The multistage internal architecture is designed to progressively increase pressure across the sequence, ensuring that suction lift and delivery pressure remain balanced even during varying load conditions. This geometry facilitates smooth circulation while mitigating the risk of cavitation during start-up cycles.
Protection is managed via an IP55 rated TEFC surface motor, which is fully enclosed to shield internal components from dust and moisture ingress. The pump utilizes a high-grade AISI 316 stainless steel casing, offering superior resistance to chemical attack and long-term structural integrity. Installation is streamlined through standardized 25 mm suction and discharge ports, ensuring full compatibility with common liquid transport configurations.
Features:
- Integrated 2-pole squirrel-cage motor configuration for consistent operation
- Silicon carbide and carbon resin mechanical seal materials for liquid integrity
- AISI 316 stainless steel casing construction to withstand corrosive fluid exposure
- Total Enclosed Fan Cooled (TEFC) exterior design for IP55 environmental protection
- Designed for compliant liquid handling within drinking water system standards
- Compact footprint compatible with narrow manifold piping installations

How is the electric motor on this booster rated in kilowatts, supply voltage, and current draw?
Running on 220–240 V, 50 Hz, single-phase, the 1HM25N11M features a motor power rating of 1.1 kW (1.5 HP) with a current of 6.66 A.
What maximum working pressure capability in bar and liquid thermal boundaries are certified?
Operating within strict pressure parameters, the 1HM-25N-11M sustains a maximum working pressure capability of 16 bar (PN 16) and temperatures from -30°C to +120°C.
What vertical fluid lift and dynamic elevation capability are sustained by this pump?
Dynamic head performance on the 1HM 25N 11M peaks at approximately 146 m to elevate fluids across vertical installations.
For high volume transfer, what maximum fluid flow rate and discharge port diameter are output?
Discharge piping connections configured with Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge allow the 1HM_25N_11M to deliver a peak flow volume of approximately 40 L/Min.
How do the metallurgy specifications and mechanical seal faces ensure complete corrosion resilience?
The alloy composition of the 1HM25N11M relies on AISI 316L stainless steel pump casing, diffusers, and closed impellers, reinforced with precision seals against corrosion.
