Product Overview
The Lowara 5HM11S15T is a precision-engineered pump. Fluid transfer within specialized industrial cooling systems necessitates the use of high-efficiency hardware to maintain system uptime. This configuration leverages multistage hydraulic architecture to support demanding liquid circulation scenarios while ensuring minimal friction losses throughout the discharge cycle. Its construction is tailored for consistent, long-term duty in environments where process water quality must remain unaffected by the pump components themselves.
Performance parameters for the Lowara 5HM11S15T unit include a Max Head 79.9 m and a Max Flow 142 L/Min. Operational power is provided by a 1.5 kW motor operating at 415v, which facilitates stable fluid movement across varied load profiles. The hydraulic section is designed to meet strict ISO 9906:2012 grade standards, providing predictable pressure delivery across all stages of the manifold.
Internal dynamics are governed by a robust multistage arrangement of AISI 304 stainless steel components, which effectively manage internal pressure variations and hydraulic thrust. The mechanical seal configuration utilizes high-tolerance surfaces to prevent external leakage, while the close-coupled assembly ensures precise alignment between the motor shaft and the hydraulic wet end, minimizing vibration during operation.
Protection and housing features include an IP 55 rated motor enclosure and an IP X5 rating for the total pump assembly, suitable for ambient temperatures up to 50°C. The stainless steel body provides structural resilience against internal wear, complemented by technical thermal tolerances that allow for liquid temperatures between -10°C and +120°C.
Features:
- TEFC two-pole short-circuit squirrel-cage motor configuration
- IE3 energy efficiency motor performance architecture
- Silicon carbide and ceramic mechanical seal interface
- PPS technopolymer wear ring for hydraulic precision
- Designed for continuous duty in 50Hz electrical networks
- Class 155 (F) motor insulation for thermal stability

In corrosive water environments, what construction materials and mechanical seal metallurgy provide protection?
Featuring alloy metallurgy of AISI 304 stainless steel pump casing, diffusers, and closed impellers, the 5HM11S15T relies on elastomeric mechanical seals to guard against particulate attack and liquid corrosion.
For grid electrical connection, what power rating and operating voltage current draw energize this unit?
Operating on 380–415 V, 50 Hz, three-phase, the 5HM-11S-15T utilizes a 1.5 kW (2.0 HP) motor requiring a current feed of 3.21 A.
Across high-pressure installations, what maximum working pressure capability and temperature limits apply?
Withstanding high internal hydraulic forces, the 5HM 11S 15T delivers a maximum working pressure capability of 16 bar (PN 16) and accommodates fluid temperature limits from -30°C to +120°C.
Across vertical supply lines, what peak dynamic elevation head does this booster unit produce?
Delivering dependable vertical lift, the 5HM_11S_15T generates a maximum dynamic head of approximately 79.9 m to propel liquid upward.
Regarding fluid output, what water delivery flow volume and discharge pipe thread are featured?
Water transfer volume reaches a peak delivery flow of approximately 142 L/Min on the 5HM11S15T, connecting via Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge.
