Product Overview
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 0.95 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

Which stainless alloys are engineered into the casing and impellers to stop corrosion?
All-metal stainless construction safeguards the 3HM12S09M, utilizing AISI 304 stainless steel casing and closed impeller alloy metallurgy to eliminate fluid corrosion and particulate wear.
What motor kilowatt rating and electrical voltage supply drive this circulation booster pump?
Motor power on the 3HM-12S-09M is rated at an electrical output of 0.95 kW (1.3 HP), drawing an electrical current of 5.72 A from a 220–240 V, 50 Hz, single-phase power supply.
How is reverse flow prevented when installing this circulation pump in a horizontal position?
Installation of the 3HM 12S 09M calls for a sturdy horizontal floor base with perimeter drainage, accompanied by an external in-line non-return check valve to stop system backflow.
What peak vertical head elevation can this circulation multistage pump generate?
Delivering steady vertical lift, the 3HM_12S_09M generates a maximum dynamic head of approximately 87.8 m to propel fluid across high elevation rises.
What maximum delivery flow volume does this multistage circulation pump discharge across piping?
Water transfer volume reaches a peak delivery flow of approximately 73.3 L/Min on the 3HM12S09M, connecting via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
