Product Overview
The Lowara 3HM11S09M serves as a precision-engineered solution for diverse cooling systems and industrial process water needs. Built to facilitate stable liquid movement, this horizontal multistage electric pump addresses the technical demands of high-pressure circulation tasks where flow consistency remains critical. Its configuration ensures that liquid handling occurs within a controlled, efficient environment, making it suitable for both professional service integration and rigorous site-specific installations.
Hydraulic capacity for this unit reaches a Max Head 77.5 m and a Max Flow 73.3 L/Min. Engineered for 240v power supply, the unit operates at a maximum power of 0.95 kW, consuming a rated current of 5.45 Amps. The plumbing connection size is fixed at 25 mm for both suction and delivery, allowing for standard integration into existing stainless steel piping networks. This unit is designed to handle fluid temperatures ranging from -10°C to +60°C.
Construction centres on a fully integrated stainless steel hydraulic design. The internal arrangement utilizes a series-stage assembly that optimizes pressure generation without sacrificing the mechanical stability of the rotating components. The closed design of the internal flow path maintains volumetric efficiency across various loading conditions, ensuring that the pump effectively manages the demands of continuous circulation without cavitation or flow degradation.
Designed as a close-coupled unit, the pump features a robust structural alignment between the motor and the liquid end. The assembly is protected by an IP55 rating, ensuring resistance against environmental debris when installed in professional settings. The motor incorporates TEFC cooling technology to prevent thermal accumulation during peak operation.
Features:
- Integrated TEFC squirrel-cage 2-pole motor architecture
- AISI 304 grade stainless steel hydraulic casing
- Suitable for continuous operational duty cycles
- Equipped with standard G 1 inch threaded suction and delivery ports
- Compliance with global EN 60335 and EN 60034 standards
- Static sealing system using EPDM elastomers for chemical stability

What water flow volume and connection pipe dimensions are engineered into this booster?
Supplying steady fluid flow across piping circuits, the 3HM11S09M provides a maximum delivery flow volume of approximately 73.3 L/Min with Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What metallurgy and mechanical seal components provide durability against fluid corrosion in this unit?
Resisting fluid corrosion and mineral attack, the 3HM-11S-09M utilizes an AISI 304 stainless steel pump body, matching AISI 304 stainless closed impellers, and chemical attack resistant mechanical seal materials.
What electrical power rating and single-phase current draw apply to this booster motor?
Electrical power feed for the 3HM 11S 09M requires a 220–240 V, 50 Hz, single-phase connection, delivering a motor power rating of 0.95 kW (1.3 HP) with an electrical running current of 5.45 A.
Where should this clean water booster be anchored on a horizontal mounting base with drainage?
To prevent reverse flow and maintain line pressure, the 3HM_11S_09M must be paired with an external non-return check valve while anchored securely on a horizontal mounting base with proper drainage.
What dynamic lift head and upward push capability are engineered into this booster?
Elevating water through vertical supply lines, the 3HM11S09M achieves a peak dynamic head rating of approximately 80.7 m at full elevation push.
