Lowara 3HM13S11M Close-Coupled Stainless Continuous Multistage Pump for Water Transfer with Closed Impeller

The Lowara 3HM13S11M serves as a precision-engineered solution for liquid transfer and pressure regulation in diverse professional environments. By integrating a multistage hydraulic arrangement, this unit excels at moving clean water through secondary loops, cooling circuits, or pressurization systems where consistent, stable flow dynamics are required. Its compact horizontal orientation facilitates integration into constrained plant room layouts or skid-mounted water management assemblies, ensuring straightforward piping alignment.

Hydraulic output is managed by an efficient motor providing a maximum power rating of 1.42 kW / 240v. The pump architecture supports a performance capacity reaching a Max Head 93.1 m and a Max Flow 73.3 L/Min. Engineered for clean water, the unit features 25 mm inlet and outlet porting, maintaining the strict hydraulic integrity essential for high-pressure irrigation or process water tasks. The technical design ensures the motor remains operational under continuous loads while meeting stringent efficiency standards.

Construction priority is placed on structural longevity and fluid-path purity. The pump utilizes an AISI 304 stainless steel hydraulic assembly, providing a corrosion-resistant environment for the internal liquid flow. The staging configuration minimizes turbulence while maximizing the energy transfer efficiency inherent to the e-HM series design. This configuration allows for smooth pressure transition across each stage, effectively dampening vibrational stress during high-head operation while ensuring long-term seal stability.

Designed for demanding service, the unit incorporates an IP55 rated motor with a TEFC enclosure to protect internal electrical components against ingress in humid or industrial settings. The structural design employs a robust stainless steel body connected directly to the motor flange, minimizing potential leak paths associated with traditional pump architectures. Maintenance access is simplified through a modular design that facilitates straightforward seal inspection and routine service procedures as required by industrial duty cycles.
