Lowara 3HM13N11M Efficient Stainless Steel Multistage Pump for Cooling Systems with Closed Impeller

Fluid transfer across demanding industrial cooling circuits requires the structural integrity found in this AISI 316 stainless steel assembly. Constructed to handle a variety of aggressive, high-purity liquids, the unit excels in environments where material resilience directly dictates operational lifespan. By integrating a multistage architecture, it provides the steady hydraulic force necessary to overcome resistance in complex plumbing configurations while maintaining consistent circulation rates for sensitive machinery cooling tasks.

Operational threshold limits are defined by a Max Head 93.1 m alongside a Max Flow 73.3 L/Min. Powering this output is a 1.42 kW / 240v motor engineered for continuous load requirements. The hydraulic geometry ensures that performance remains efficient even under the variations inherent in closed-loop systems, providing a reliable foundation for sustained industrial cooling and pressure augmentation without deviating from established flow curves.

Engineering dynamics are governed by a closed impeller arrangement designed to optimize energy conversion and minimize turbulence during operation. This configuration facilitates superior suction stability and uniform discharge pressure, which is vital for process systems where fluctuation could result in thermal inefficiencies. The balanced internal geometry works in conjunction with high-precision internal components to reduce vibrational stress, ensuring longevity even at peak motor speeds.

Housing the internals is a single-piece stainless steel shell that provides a robust barrier against external environmental factors and internal chemical interactions. The TEFC motor is shielded to an IP55 rating, protecting against dust and low-pressure water ingress, while the insulation class 155 (F) handles thermal elevation effectively. Installation is straightforward with 25 mm threaded connections, allowing for a secure fit within existing piping networks using standard mounting orientations.
