Product Overview
The Lowara 1HM22S15T provides efficient and reliable pumping performance. Corrosive, chemically active municipal supply loops benefit from the resilient construction of this horizontal multistage electric unit. It integrates seamlessly into professional settings where precise flow control for cooling systems or clean process liquid handling remains a critical operational requirement. The architecture provides constant suction performance across extended industrial cycles without degradation of internal hydraulic components.
Operational threshold limits are defined by a Max Head 131 m alongside a Max Flow 40 L/Min. This configuration utilizes a 1.5 kW motor input, specifically engineered for 415v three-phase supply connectivity. The hydraulic output remains consistent throughout the duty cycle, ensuring stable fluid delivery for demanding pressure boosting applications in commercial and specialized environments.
Fluid dynamics are governed by a multistage impeller arrangement crafted from AISI 304 stainless steel. This design focus minimizes turbulence within the casing, allowing for a refined balance between velocity and lift capacity. By utilizing a centrifugal sequence, the unit maintains hydraulic efficiency throughout high-pressure cycles, providing a smooth, continuous stream of clean liquid to downstream systems.
Protection is managed via an IP55 rated TEFC motor enclosure, utilizing an insulation Class 155 (F) to prevent thermal stress during sustained loading. The assembly features a sleeve-style exterior casing with TIG-welded seams for maximum structural integrity. Mechanical seal integrity is supported by specialized elastomer components, while the overall frame is mounted for straightforward integration into 25mm pipework systems.
Features:
- Integrated silicon carbide and EPDM mechanical sealing elements
- Surface mounted 2-pole asynchronous motor geometry
- Compliant with ISO 9906:2012 Grade 3B hydraulic standards
- WRAS and ACS certification for potable water contact
- Technopolymer PPS wear ring for reduced internal friction
- Operational ambient temperature capacity up to 50°C
