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 0.50 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
