Product Overview
The Lowara 3HM13S11T provides efficient and reliable pumping performance. Suction-side fluid handling in specialized liquid circuits requires precise control and mechanical stability. This unit manages fluid movement across complex manifolds where consistency is critical. By utilizing a high-efficiency architecture, it addresses the technical requirements of industrial water supply loops, ensuring steady flow velocity under varying operational loads. The horizontal configuration facilitates integration into existing rack-mounted skids or compact mechanical rooms without needing excessive floor space.
Operational threshold limits are defined by a Max Head 96.1 m alongside a Max Flow 73.3 L/Min. This assembly is driven by a 1.1 kW / 415v motor, engineered for consistent torque delivery in three-phase electrical environments. Thermal efficiency is maintained through the integration of an IE3-compliant drive system, which minimizes energy losses during continuous run cycles while meeting strict output expectations for pressurized process water systems.
Fluid dynamics are governed by a multistage arrangement, employing precision-engineered stainless steel components to reduce turbulence. The internal design minimizes friction, allowing for high-pressure generation relative to the total liquid throughput. By utilizing a multistage architecture, the pump minimizes cavitation risks and vibration during high-head operation, contributing to a smoother circulation profile in closed or open-loop hydraulic installations.
Housing consists of AISI 304 stainless steel, providing structural integrity in aggressive environments. The motor is protected to IP 55 standards, with the complete electric assembly rated at IP X5 to guard against liquid ingress. Connection ports are strictly sized at 25mm for both suction and delivery, allowing for straightforward integration into existing pipework. The mechanical seal interface utilizes advanced synthetic elastomers, suitable for operation in liquid temperatures ranging from -10°C to +120°C.
Features:
- Certified compliant with ISO 9906:2012 Grade 3B hydraulic performance standards
- Surface-mounted TEFC two-pole short-circuit squirrel-cage motor configuration
- Silicon carbide and alumina mechanical seal interface components
- Compatible with WRAS and ACS certified clean water transfer applications
- Reinforced technopolymer PPS wear ring for internal hydraulic precision
- Insulation class 155 (F) for thermal endurance in industrial climates

Which stainless alloys are engineered into the casing and impellers to stop corrosion?
Corrosion protection across the 3HM13S11T is maintained through an AISI 304 stainless steel pump body, closed impellers, and durable mechanical seals.
What supply voltage and motor power in kilowatt are engineered into this water transfer unit?
Powered through an electrical power line of 380–415 V, 50 Hz, three-phase, the 3HM-13S-11T provides a motor power rating of 1.1 kW (1.5 HP) with an electrical current of 2.42 A.
How should this heavy multistage pump be secured on a horizontal base to ensure proper drainage?
Horizontal surface mounting of the 3HM 13S 11T requires level foundation positioning with drainage, complemented by a check valve to prevent backflow.
What peak vertical head elevation can this circulation multistage pump generate?
Overcoming elevation resistance in multi-floor piping, the 3HM_13S_11T develops a maximum dynamic head of approximately 98.1 m.
What maximum delivery flow volume does this multistage circulation pump discharge across piping?
Connecting via threaded Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, the 3HM13S11T provides a maximum water delivery flow volume of approximately 73.3 L/Min.
