Product Overview
The Lowara 1HM12S05M is engineered for precision liquid handling in building services and demanding industrial environments. This horizontal multistage centrifugal pump is designed to provide stable, consistent pressure, making it an ideal solution for residential irrigation systems, process water transfer, and various automated boosting applications. Its architecture ensures steady flow control across diverse suction and delivery requirements, facilitating reliable operation in clean water systems where performance consistency is required.
Built for high-efficiency operation, this unit offers a Max Head 68.8 m and a Max Flow 40 L/Min. With a power rating of 0.55 kW at 240v, the pump balances energy consumption with hydraulic output. It features a robust design capable of managing fluid temperatures between -10°C and +60°C, ensuring versatility across varied temperature environments while maintaining hydraulic integrity during continuous duty cycles.
The multistage hydraulic assembly incorporates AISI 304 stainless steel components, promoting both structural resilience and hydraulic efficiency. This arrangement allows the pump to manage complex pressure requirements while maintaining a compact footprint. The design focuses on fluid dynamics optimization, reducing internal turbulence and improving overall energy conversion, which contributes to more stable pressure delivery and longer service life in intensive pumping scenarios.
Designed with a close-coupled TEFC motor, the assembly features an IP55 protection rating, safeguarding internal components against environmental debris and moisture. Plumbing connections utilize 25 mm inlet and outlet ports, enabling seamless integration into existing piping infrastructure. The pump housing is constructed from high-grade stainless steel to prevent corrosion, and the assembly utilizes standard mechanical seals to ensure leak-free operation in high-pressure applications.
Features:
- AISI 304 stainless steel hydraulic and casing components
- IP55 rated TEFC motor assembly for environmental protection
- WRAS and ACS certified materials for safe drinking water handling
- Engineered for continuous duty in building service applications
- Dual mechanical seal configuration for enhanced pressure retention
- Compact close-coupled design for simplified installation

What fluid flow volume and discharge connection threads are engineered into this unit?
Supplying steady fluid flow across piping circuits, the 1HM12S05M provides a maximum delivery flow volume of approximately 40 L/Min with Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What construction metallurgy and seal elastomers defend this circulation pump against corrosion?
Resisting fluid corrosion and mineral attack, the 1HM-12S-05M utilizes an AISI 304 stainless steel pump body, matching AISI 304 stainless closed impellers, and chemical attack resistant mechanical seal materials.
What motor power rating in kilowatt and electrical current draw apply to this single-phase pump?
Electrical power feed for the 1HM 12S 05M requires a 220–240 V, 50 Hz, single-phase connection, delivering a motor power rating of 0.55 kW (0.75 HP) with an electrical running current of 3.96 A.
Where is horizontal surface mounting advised for this transfer unit to maintain floor drainage?
To prevent reverse flow and maintain line pressure, the 1HM_12S_05M must be paired with an external non-return check valve while anchored securely on a horizontal mounting base with proper drainage.
What vertical head elevation and dynamic lift pressure apply to this transfer pump?
Elevating water through vertical supply lines, the 1HM12S05M achieves a peak dynamic head rating of approximately 70.8 m at full elevation push.
