Product Overview
Engineered for precise fluid movement, this Lowara 1HM16S07M horizontal multistage centrifugal pump is designed for process water handling and industrial circulation duties where consistent pressure and flow stability are required. It excels in applications involving the transfer of clean, non-aggressive liquids, offering a reliable solution for complex water circuits in light industrial environments. The compact configuration allows for easy integration into existing pipework systems, effectively meeting the requirements of demanding hydraulic operations.
The unit is powered by a high-efficiency 0.75 kW motor capable of providing reliable output across various duty points. Its hydraulic capability is defined by a Max Head 93.8 m and a Max Flow 40 L/Min, ensuring sufficient performance for most pressure boosting tasks. Plumbing connections are maintained via a 25 mm inlet and 25 mm outlet, facilitating streamlined installation. The assembly is built to withstand operating pressures up to 16 bar, provided within a compact TEFC motor arrangement.
Hydraulic efficiency is central to the design of the 1HM series, featuring a multistage arrangement that optimizes liquid velocity and head pressure. Each stage is meticulously balanced to minimize internal turbulence, which translates into stable flow delivery during continuous operation. The hydraulic path is designed to sustain energy efficiency, reducing operational heat build-up and ensuring the motor maintains thermal stability under load, even when managing liquids at temperatures ranging from -10°C to +60°C.
Construction focuses on long-term mechanical integrity, utilizing AISI 304 stainless steel for the hydraulic components to ensure resistance against corrosion in processed water environments. The pump features a robust close-coupled design protected by an IPX5 rating, ensuring safety against moisture and external debris. The integrated squirrel-cage motor is engineered for quiet operation, while the pump's mechanical seal configuration adheres to strict industrial standards to prevent leakage and improve longevity in demanding usage cycles.
Features:
- AISI 304 stainless steel hydraulic construction
- TEFC motor with IP55 protection class rating
- IE3 motor efficiency architecture for reduced consumption
- Integrated O-ring seal system for leak prevention
- Certified for safe drinking water circulation applications
- Designed for 2-pole asynchronous 50 Hz operational speed

What supply voltage and motor power in kilowatt are engineered into this single-phase unit?
Powered by a 220–240 V, 50 Hz, single-phase electrical feed, the 1HM16S07M delivers a motor power rating of 0.75 kW (1.0 HP) at an electrical current draw of 4.60 A.
What horizontal mounting orientation and external check valve protection are recommended for this unit?
Backflow prevention across horizontal pipe runs requires installing an external non-return check valve immediately downstream of the 1HM-16S-07M, which must rest on a horizontal base with drainage.
What peak vertical elevation head does this water circulation pump achieve?
Vertical lift pressure is developed by the 1HM 16S 07M, which maintains a peak dynamic head capability of approximately 93.4 m across its stages.
What peak water flow volume can this stainless circulation pump discharge through its outlet?
Plumbing connection lines interface with the 1HM_16S_07M via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, discharging a maximum delivery flow volume of approximately 40 L/Min.
How does the stainless alloy casing construction resist corrosion and particulate erosion?
Corrosion defense across the 1HM16S07M relies on high-grade AISI 304 stainless steel casing alloys and closed stainless impellers with EPDM elastomers to protect against chemical attack.
