Product Overview
The Lowara 3HM03P05M is engineered for residential pressure boosting and clean water transfer applications, providing consistent hydraulic performance for small to medium building services. This horizontal multistage pump is specifically suited for homeowners and property managers seeking a compact, reliable solution for irrigation systems, domestic water supply, or general liquid movement tasks where space is constrained.
Built for demanding operation, the unit features a 0.5 kW / 240v motor and an efficient multistage design that achieves a Max Head 31.5 m and Max Flow 70 L/Min. The pump incorporates high-grade AISI 304 stainless steel construction, ensuring long-term structural integrity while maintaining a compact footprint for straightforward integration into existing plumbing configurations with 25mm inlet and outlet ports.
This series utilizes advanced hydraulic technology, combining a robust stainless steel body with precision-balanced Technopolymer components to minimize axial thrust and reduce wear on motor bearings. The compact, single-piece fabricated body design significantly reduces potential leak points, while the TEFC motor configuration ensures stable thermal management during continuous operational cycles in various environments.
Installation is simplified through standard threaded connections and a lightweight, 7 kg architecture that accommodates diverse mounting requirements. Safety is prioritized through integrated automatic reset overload protection for the single-phase motor, alongside mechanical seals that comply with international standards for durability and resistance in residential clean water handling duties.
