Product Overview
Engineered for demanding civil and industrial environments, the Lowara COM 350/05 is a specialized centrifugal pump designed to handle clean liquid transfer tasks with precision. This unit serves facility managers and technical installers who require a material-compliant solution for systems where water quality is critical, such as small process circuits or circulation loops. By leveraging the corrosion-resistant properties of its 316L stainless steel build, the pump ensures operational longevity in environments where traditional cast iron or basic plastic units might succumb to fatigue. It is particularly effective for installations that necessitate a balance of consistent hydraulic output and space-efficient footprint, providing a reliable core for liquid movement in diverse technical setups.
The architecture of this pump centres on a single-impeller design that facilitates reliable flow rates across its operating range. When integrated into a properly sized circuit, it features a maximum capacity of Max Head 9.2 m and Max Flow 350 L/Min. Powering this unit is a robust 0.79 kW / 240v motor which operates with a rated current of 3.41 Amps. The inlet and outlet plumbing connections are standardized at 40 mm and 32 mm respectively, allowing for straightforward integration into existing pipework configurations without the need for complex custom adapters or non-standard fittings, thereby streamlining the installation process for professional contractors.
Technologically, the pump is built around a close-coupled asynchronous motor, which includes an enclosed design with external ventilation for improved thermal management during operation. The open impeller system is intentionally crafted to facilitate the movement of clean liquids with minimal turbulence, enhancing overall hydraulic efficiency. The inclusion of internal automatic reset thermal overload protection provides a crucial layer of safety for single-phase operation, preventing damage during unexpected overcurrent events. This combination of motor architecture and hydraulic design ensures that the pump remains highly responsive to the fluid transfer requirements of modern process water systems and circulating installations.
Installation and environmental suitability are addressed through a compact mechanical configuration supported by a galvanized steel foot for stable mounting. The internal components, including the standard FKM elastomers and carbon/ceramic mechanical seal, are selected to withstand a broad liquid temperature range from -10°C to +110°C, making the unit versatile across multiple thermal settings. The IP55 protection rating ensures the unit is well-guarded against external contaminants and moisture in industrial settings. Operators should ensure the suction and discharge lines are correctly aligned to the 40 mm and 32 mm openings to maintain the intended pressure rating of 8 bar during full-load conditions.
Features:
- Integrated automatic reset thermal overload protection for safe single-phase operation
- AISI 316L stainless steel hydraulic housing and shaft extension for corrosion resistance
- Carbon and ceramic mechanical seal interface with FKM elastomer componentry
- TEFC enclosure rated for IP55 protection against dust and low-pressure water jets
- Asynchronous squirrel cage motor design optimized for continuous duty cycles
- Galvanized steel support footing for vibration dampening and secure mounting
