The Lowara 3HM12S09M is a horizontal multistage centrifugal pump engineered for demanding industrial and building services environments where consistent flow is required. This unit is specifically configured for liquid circulation, pressure boosting, and water transfer tasks, providing a stable hydraulic output across various installation configurations. By utilizing a multistage design, it efficiently generates pressure for process water handling and cooling systems, ensuring smooth operation even in restricted spaces where a compact, close-coupled footprint is essential.
Hydraulic performance is defined by a Max Head of approximately 83.7 m and a Max Flow of approximately 73.3 L/Min. This model incorporates a powerful 1.31 kW / 240v motor architecture to maintain peak efficiency. The intake and delivery piping connections are both 25 mm, allowing for seamless integration into existing stainless steel or standard plumbing infrastructures. The pump is rated for liquid temperatures ranging between -10°C and +60°C, providing the thermal flexibility required for diverse industrial applications.
Construction relies on AISI 304 stainless steel, providing long-term resistance to corrosion and liquid interactions. The multistage internal arrangement ensures that energy consumption is minimized while maximizing output pressure, resulting in stable flow characteristics during operation. The hydraulic path has been precision-engineered to reduce turbulence, which contributes to more predictable performance in pressure-sensitive systems and significantly assists in maintaining operational consistency during extended duty cycles.
This pump features a TEFC motor protected by an IP55 housing to isolate internal components from environmental debris. The assembly utilizes an advanced sealing system designed to prevent leakage at the shaft interface, supported by an insulation class 155 (F) rating. Its horizontal layout is optimized for installation on rigid surfaces, and the structure is specifically weighted at 14 kg for ease of mounting. It adheres to EN 60335-2-41 and related standards to verify safety for clean liquid handling environments.
Features:
- Integrated 2-pole asynchronous squirrel-cage motor configuration
- Silicon carbide and carbon mechanical seal face materials
- EPDM elastomer components for chemical compatibility
- Compliance with international ErP 2009/125/EC directives
- Balanced rotating assembly to minimize operational vibration
- WRAS and ACS certification for drinking water compatibility
