Product Overview
The Lowara 3HM03S05M is engineered for diverse building services and industrial liquid transfer tasks. This horizontal multistage centrifugal pump is specifically optimized to maintain stable flow in cooling systems and clean water distribution environments. Its compact configuration allows for installation in space-constrained mechanical rooms or integrated equipment skids where consistent, reliable pressure is required for demanding operational cycles.
Designed for precision hydraulic performance, this unit achieves a Max Head 21.9 m and a Max Flow 73.3 L/Min. It utilizes a 0.5 kW motor to drive the multi-stage array, ensuring efficient energy consumption while delivering the necessary pressure for complex piping layouts. The liquid handling architecture accommodates temperatures ranging from -10°C to +60°C, making it adaptable to various standard facility requirements.
Construction involves a robust AISI 304 stainless steel assembly, including the internal hydraulic components. The multistage arrangement balances the axial loads effectively, contributing to quiet operation and reduced vibration during continuous use. The close-coupled design connects the pump body directly to the motor flange, utilizing high-grade sealing technology to ensure structural alignment and prevent internal fluid bypass across the stages.
Installation is facilitated by 25 mm suction and 25 mm delivery connections, allowing for standard plumbing integration. The motor is a TEFC (Totally Enclosed Fan Cooled) 2-pole unit, protected by an IP55 classification for the motor and IPX5 for the overall electric pump configuration. Thermal overload protection is integrated into the electrical system to safeguard the motor windings during potential over-current events.
Features:
- Integrated AISI 316 mechanical seal surfaces
- Squirrel-cage asynchronous motor technology
- WRAS and ACS certified for potable water compatibility
- EPDM elastomer sealing gaskets for chemical resistance
- Single O-ring casing sealing arrangement for leak mitigation
- Horizontal orientation with foot-mounted base for stability

What electrical kilowatt rating and single-phase supply voltage feed this clean water pump?
Powered by a 220–240 V, 50 Hz, single-phase electrical feed, the 3HM03S05M delivers a motor power rating of 0.50 kW (0.7 HP) at an electrical current draw of 2.48 A.
Where is horizontal foundation mounting recommended for this clean water booster with drainage?
Backflow prevention across horizontal pipe runs requires installing an external non-return check valve immediately downstream of the 3HM-03S-05M, which must rest on a horizontal base with drainage.
What peak dynamic head and vertical lift elevation can this clean water pump produce?
Vertical lift pressure is developed by the 3HM 03S 05M, which maintains a peak dynamic head capability of approximately 22.3 m across its stages.
What maximum water flow volume and discharge pipe connection apply to this supply pump?
Plumbing connection lines interface with the 3HM_03S_05M via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, discharging a maximum delivery flow volume of approximately 73.3 L/Min.
What stainless alloy metallurgy and closed impellers protect this clean water pump from corrosion?
Corrosion defense across the 3HM03S05M relies on high-grade AISI 304 stainless steel casing alloys and closed stainless impellers with EPDM elastomers to protect against chemical attack.
