Product Overview
The Lowara 3HM14S11M is engineered for high-demand clean water circulation in commercial and industrial cooling applications. This horizontal multistage centrifugal pump excels in maintaining consistent flow rates where stable pressure output is required for process-critical temperature control environments. Its compact construction ensures straightforward integration into existing pipework configurations, offering a stable solution for specialized water transfer duties.
Hydraulic performance for this unit is rated at Max Head 99.6 m and Max Flow 73.3 L/Min. The electric motor delivers a maximum power of 1.1 kW at 240v, operating with an efficient 2-pole configuration. The suction and delivery ports are 25 mm in diameter, providing reliable connection integrity for fluid systems requiring precise liquid handling and sustained volumetric circulation throughout daily operational cycles.
Featuring an advanced multi-stage design, this pump achieves fluid energy transfer via internal staging, ensuring stable pressure even when handling fluctuating loads. The assembly utilizes AISI 304 stainless steel components throughout the hydraulic end, maintaining fluid purity and resistance to corrosion. This staging arrangement optimizes the movement of liquids, resulting in efficient energy conversion and consistent performance across various building service requirements.
Designed as a close-coupled unit, the pump utilizes a TEFC motor arrangement to provide environmental protection during operation. The system is suited for liquid temperatures ranging from -10°C to +60°C and is housed within a structure that supports straightforward mechanical maintenance. The overall assembly reflects a focus on technical alignment with industry standards for clean water movement and safe installation practices in indoor or protected environments.
Features:
- TEFC motor enclosure rated to IP55 protection class
- AISI 304 stainless steel hydraulic construction for fluid integrity
- Suitable for continuous operational duties in clean liquid systems
- Insulation class 155 (F) motor winding design
- Dual O-ring casing seal system for enhanced pressure retention
- Compact direct-coupled design for minimized installation footprint
