Product Overview
The Lowara 1HM22S09M provides efficient and reliable pumping performance. This horizontal multistage centrifugal pump serves as a primary solution for demanding clean liquid transfer within industrial and building service environments. Engineered for versatility, the system excels in process water handling, small-scale pressure boosting, and systems requiring consistent, non-abrasive fluid movement where operational precision is paramount.
The unit is powered by a high-efficiency motor with a power rating of 0.95 kW and 240v input. It delivers significant hydraulic output for its class, featuring a Max Head 129 m and a Max Flow 40 L/Min. These metrics ensure stable performance across various discharge requirements in managed piping installations.
Construction focuses on longevity and hydraulic stability, utilizing AISI 304 stainless steel for both the housing and the internal hydraulic components. The multistage design allows for higher pressure development while maintaining a compact footprint, facilitating efficient flow generation even in constrained site locations or complex liquid distribution networks.
Installation is simplified through a close-coupled arrangement with threaded 25 mm suction and delivery ports. The pump is protected by an IP55 rated motor enclosure, ensuring suitability for fixed, enclosed environments. Designed for continuous duty, the architecture minimizes leakage potential through robust sealing techniques suited for standard plumbing configurations.
Features:
- Integrated 2-pole TEFC asynchronous motor for thermal control
- AISI 304 stainless steel hydraulic chamber construction
- Suitable for high-pressure clean water circulation duties
- Includes standard EPDM elastomer sealing for fluid compatibility
- Horizontal orientation with direct-drive motor coupling
- Engineered for low-noise operation in static installations

What peak delivery flow rate does this close-coupled multistage pump provide across plumbing?
Supplying steady fluid flow across piping circuits, the 1HM22S09M provides a maximum delivery flow volume of approximately 40 L/Min with Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
How does the stainless construction protect this multistage booster from aggressive mineral attack?
Resisting fluid corrosion and mineral attack, the 1HM-22S-09M utilizes an AISI 304 stainless steel pump body, matching AISI 304 stainless closed impellers, and chemical attack resistant mechanical seal materials.
What electrical power in kilowatt and operating current feed this single-phase transfer unit?
Electrical power feed for the 1HM 22S 09M requires a 220–240 V, 50 Hz, single-phase connection, delivering a motor power rating of 0.95 kW (1.3 HP) with an electrical running current of 5.76 A.
What horizontal mounting guidelines and non-return check valve piping apply to this pressure pump?
To prevent reverse flow and maintain line pressure, the 1HM_22S_09M must be paired with an external non-return check valve while anchored securely on a horizontal mounting base with proper drainage.
What peak dynamic head and upward lift capability does this pressure pump maintain?
Elevating water through vertical supply lines, the 1HM22S09M achieves a peak dynamic head rating of approximately 128 m at full elevation push.
