Product Overview
Corrosive, chemically active municipal supply loops benefit from the resilient construction of the Lowara 1HM11N05M multistage unit. The assembly functions effectively within varied fluid handling environments, providing consistent pressure for process cooling, water treatment, or small-scale commercial filtration systems. By utilizing high-grade materials, the pump maintains structural integrity when exposed to demanding chemical concentrations often found in process water management.
Operational threshold limits are defined by a Max Head 63.5 m alongside a Max Flow 40 L/Min. Powering these metrics is a 0.55 kW single-phase motor, which operates at a current draw of 3.82 Amps. This specific hydraulic configuration ensures that laminar flow remains stable even when subjected to varying system resistances, enabling precise control over liquid circulation within closed or open piping networks.
Fluid dynamics are governed by a multistage impeller arrangement crafted from AISI 316L stainless steel, designed to maximize kinetic energy conversion across each stage. The internal geometry supports high-pressure output while minimizing turbulent losses, ensuring that the velocity profile remains uniform from the 25 mm inlet through to the discharge port. This configuration facilitates consistent performance, particularly in scenarios requiring steady, non-pulsing liquid delivery over prolonged duty cycles.
Housing the internals is a single-piece stainless steel casing, reinforced to handle operating pressures up to 16 bar. The TEFC motor is shielded under an IP55 protection rating, featuring Class 155 insulation to mitigate heat accumulation during intensive use. Mechanical seals incorporate silicon carbide and carbon components to reduce friction and leakage risks, ensuring the unit remains hermetically secure under constant load. Mounting is facilitated by a robust bracket, with the entire pump weight balanced at 12 kg for installation stability.
Features:
- Integrated 2-pole motor operating at 2900 rpm
- Silicon carbide mechanical seal faces for wear resistance
- EPDM elastomer sealing components throughout the hydraulic path
- Compliant with ISO 9906 Grade 3B hydraulic standards
- WRAS and ACS certified for potable water contact
- Total Enclosed Fan Cooled motor geometry for thermal regulation

At peak demand, what fluid flow rate and discharge pipe thread sizing apply to this booster?
Discharge delivery flow peaks at a volume of approximately 40 L/Min on the 1HM11N05M, connecting via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What alloy metallurgy specifications and mechanical seal materials ensure long-term corrosion resistance?
Produced from AISI 316L stainless steel pump casing, diffusers, and closed impellers, the 1HM-11N-05M relies on precision mechanical seals to prevent corrosion damage.
For facility power integration, what electrical motor power rating and voltage feed are required?
The electrical power rating of the 1HM 11N 05M features a 0.55 kW (0.75 HP) motor fed by 220–240 V, 50 Hz, single-phase at 3.82 A.
For safe long-term duty, what maximum working pressure capability and thermal limits are engineered?
Delivering safe pressure containment, the 1HM_11N_05M sustains a maximum working pressure limit of 16 bar (PN 16) across temperatures from -30°C to +120°C.
To elevate clean liquid upward, what maximum vertical head does this multistage pump reach?
Vertical fluid lift reaches a maximum dynamic head of approximately 63.5 m through the impellers of the 1HM11N05M.
