Product Overview
Ensuring stable hydraulic distribution across high-demand industrial layouts relies on the precision-engineered architecture of the Lowara 3HM04N05M horizontal unit. By integrating specialized AISI 316 stainless steel components, the pump maintains structural integrity when handling aggressive or high-purity process fluids that would compromise standard casting materials. Its configuration is specifically tailored for tight installations where reliable, horizontal suction performance is non-negotiable for system-wide stability.
Operational threshold limits are defined by a Max Head 28.7 m alongside a Max Flow 73.3 L/Min for precise load balancing. Powered by a 0.5 kW motor operating at 230v, the hydraulic output remains consistent throughout fluctuating process demands. The system architecture is calculated for medium-load requirements, offering a stable curve for cooling systems or chemical dosing loops where flow variance must stay within strict tolerance margins for effective operation.
Fluid dynamics are governed by a multi-stage arrangement featuring AISI 316L stainless steel impellers, designed to reduce turbulent energy losses during high-velocity transition stages. This mechanical configuration supports the unit in managing high suction requirements while maintaining quiet operation under load. The internal hydraulic design leverages the modular e-HM series geometry, ensuring smooth liquid transport and sustained pressure throughout the active circulation cycle without the risk of mechanical cavitation.
Housing consists of a single-piece fabricated AISI 316 stainless steel body with advanced O-ring sealing, ensuring total enclosure and containment of the pumped medium. The motor is a TEFC 2-pole unit with IP 55 ingress protection, suitable for ambient temperatures ranging from -15°C up to +45°C. Mounted on a vibration-dampening bracket, the assembly ensures alignment stability for the rotating shaft, while the standard 25 mm threaded suction and delivery ports simplify installation into pre-existing municipal or factory plumbing infrastructure.
Features:
- Integrated silicon carbide mechanical seal faces for abrasive resistance
- AISI 316 stainless steel hydraulic components for total corrosion mitigation
- IP 55 motor protection for environmental and dust ingress suppression
- Short-circuit squirrel-cage rotor for efficient torque engagement
- WRAS and ACS certified for safe clean water and process liquid handling
- Compact single-piece fabrication for space-constrained industrial plumbing

In vertical pipe networks, what peak elevation head is developed by this multistage pump?
Vertical supply pressure reaches a maximum dynamic head of approximately 28.7 m on the 3HM04N05M.
What delivery flow volume and discharge pipe connection sizing does this multistage booster feature?
Fluid circulation lines connect to the 3HM-04N-05M via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, which outputs a maximum delivery flow volume of approximately 73.3 L/Min.
What construction materials and mechanical seal components safeguard this pump against corrosion?
Metallurgy specifications for the 3HM 04N 05M employ AISI 316L stainless steel pump casing, diffusers, and closed impellers paired with mechanical face seals for corrosion defense.
For safe electrical energization, what voltage current requirements and motor kilowatt rating apply?
Motor specifications on the 3HM_04N_05M demand a power rating of 0.5 kW (0.7 HP) on 220–240 V, 50 Hz, single-phase drawing 2.64 A.
How do the maximum working pressure rating and liquid temperature boundaries protect this unit?
Thermal endurance on the 3HM04N05M accommodates liquid temperatures from -30°C to +120°C with a maximum working pressure limit of 16 bar (PN 16).
