Lowara 3HM17S15T Stainless Steel IE3 Multistage Centrifugal Pump for Liquid Transfer with Closed Impeller

Maintaining high-pressure consistency across industrial supply architectures requires the precise hydraulic performance offered by this multistage centrifugal assembly. Operations requiring a continuous transfer of clean, non-aggressive fluids within process cooling loops or pressure boosting networks benefit from its stable, multistage design. The unit manages suction-side demands effectively, providing the necessary lift for complex multi-level piping configurations where consistent delivery is critical for operational uptime.

Operational threshold limits are defined by a Max Head of approximately 126 m alongside a Max Flow of approximately 73.3 L/Min. This pump incorporates a 1.71 kW / 415v motor designed for intensive usage cycles. Electrical consumption is balanced by the integration of high-efficiency motor technology, ensuring that power input translates directly into flow performance while maintaining a steady current draw of 3.13 Amps across standard three-phase electrical environments.

Fluid dynamics are governed by a multistage arrangement that sequences water through a series of closed internal channels to incrementally increase pressure. This architecture reduces internal turbulence and improves the overall hydraulic efficiency profile of the pump. The suction process is optimized for smooth, non-cavitating operation, ensuring that the internal components maintain fluid movement stability even under high-load conditions characteristic of demanding industrial applications.

Construction revolves around an AISI 304 stainless steel casing, providing a clean surface that is resistant to common oxidation and chemical exposure found in industrial settings. The motor is protected by an IP55 enclosure, which shields electrical windings from environmental debris and moisture, while the liquid end operates with an IPX5 rating. Mounting is facilitated through a robust close-coupled configuration that secures the motor and hydraulic housing in strict alignment to minimize vibrations and structural stress.
