Product Overview
The Lowara 1HM22N09M provides efficient and reliable pumping performance. Achieving stable water pressure across multi-storey industrial facilities or precision process loops requires the consistent flow dynamics provided by this horizontal multistage unit. The configuration is specifically tailored for handling non-corrosive to moderately aggressive liquids where material longevity is a primary concern. Its compact, close-coupled orientation ensures straightforward integration into existing piping layouts where floor space remains at a premium. Suction and discharge operations remain highly stable under varying load conditions, making it suitable for both continuous-duty cycles and intermittent pressurized supply requirements within commercial environments.
Operational threshold limits are defined by a Max Head 129 m alongside a Max Flow 40 L/Min. Powering this hydraulic performance is a 0.95 kW single-phase motor, configured for 220-240V operation at a rated current of 5.75 Amps. The system maintains efficiency through 2-pole rotation, ensuring steady fluid movement without excessive cavitation under standard operating pressures. This model is engineered to provide precise fluid delivery, maintaining hydraulic stability across its entire operational envelope while adhering to strict energy efficiency guidelines.
Fluid dynamics are governed by a multistage arrangement utilizing AISI 316L stainless steel components throughout the hydraulic path. This construction ensures that all wetted parts resist particulate abrasion and chemical interaction during heavy-duty operation. The internal architecture facilitates multi-level pressure generation, allowing the pump to meet significant vertical lift requirements without relying on secondary boosting equipment. Internal seals are specified to support temperatures ranging from -10°C to +60°C, ensuring that consistent mechanical integrity is maintained during fluctuating intake conditions.
Protection is managed through an IP55-rated TEFC motor enclosure, which guards internal electrical components against dust and moisture ingress in standard industrial settings. The unit is mounted on a rigid base plate designed to mitigate vibration transmission during startup and shutdown cycles. Every component is secured with high-grade fasteners, and the entire assembly is crafted from AISI 316 stainless steel to provide high corrosion resistance. The design accommodates standard 25 mm inlet and outlet piping, simplifying mechanical installation while ensuring a secure, leak-proof connection for all pressurized plumbing setups.
