Product Overview
The Lowara 1HM25S15T provides efficient and reliable pumping performance. Corrosive, chemically active municipal supply loops benefit from the resilient construction of this horizontal multistage assembly. By utilizing a close-coupled configuration, the unit minimizes axial footprint while maximizing hydraulic stability for consistent fluid movement across complex pipe networks. It serves essential roles in irrigation, pressure boosting, and specialized industrial washing sequences where high head output is mandated.
Operational threshold limits are defined by a Max Head 149 m alongside a Max Flow 40 L/Min. Electrical power input is rated at 1.5 kW / 415v, drawing a nominal current of 2.81 Amps. This performance bracket ensures rapid pressure generation across restricted orifice diameters during peak demand cycles for cooling or heating infrastructure.
Fluid dynamics are governed by a multistage impeller arrangement crafted entirely from AISI 304 stainless steel, promoting efficiency and long-term erosion resistance. The pump series employs an internal hydraulic geometry that minimizes turbulence during high-velocity transitions, ensuring the motor workload remains steady. Sealing performance is maintained through advanced mechanical interfaces, effectively isolating the process fluid from the motor casing.
Housing consists of high-grade AISI 304 stainless steel, fully compliant with international drinking water certification standards. The motor features an IP55 protection rating with Class 155 insulation, facilitating indoor or sheltered outdoor installations. Mounting is facilitated by a robust, non-corrosive base plate, while the 25 mm inlet and delivery ports allow for direct, secure integration into standardized rigid plumbing systems.
Features:
- Integrated 2-pole asynchronous motor meeting IE3 efficiency class protocols
- Thermally protected winding design with IPX5 pump enclosure rating
- Silicon carbide and ceramic mechanical seal faces for abrasive resistance
- Suitable for continuous fluid movement in high-temperature environments
- Reinforced technopolymer PPS wear rings for sustained hydraulic efficiency
- TEFC cooling configuration for maintenance of internal thermal balance

What maximum vertical head can this multistage irrigation booster elevate upward?
Dynamic elevation capability on the 1HM25S15T provides a peak head performance of approximately 151 m.
What maximum flow volume can this irrigation multistage pump discharge through its outlet port?
Delivering clean water across pipework loops, the 1HM-25S-15T provides a maximum delivery flow volume of approximately 40 L/Min through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
Which stainless alloys are utilized in the casing and impellers to stop fluid corrosion?
Resisting abrasive particulate wear, the 1HM 25S 15T incorporates AISI 304 stainless steel alloy casing materials and closed stainless impellers.
What supply voltage and electrical power rating in kilowatt run this heavy three-phase motor?
Electrical characteristics of the 1HM_25S_15T require a 380–415 V, 50 Hz, three-phase supply, running the 1.5 kW (2.0 HP) motor power at an electrical current draw of 2.81 A.
Where should this heavy three-phase pump be mounted on a horizontal foundation base with drainage?
Anchoring the 1HM25S15T on a horizontal foundation base ensures drainage flow, while an external non-return check valve protects against pipe backflow.
