Product Overview
Achieving stable water pressure across multi-storey domestic layouts depends on the precise, consistent delivery found within the Lowara 1HM08S05T series. This horizontal multistage centrifugal unit manages high-head requirements in residential and light industrial environments where space is restricted. Its hydraulic profile is specifically tuned to maintain steady flow rates while navigating the resistance common in long-distance pipe networks or complex filtration loops. By utilizing a close-coupled geometry, the unit minimizes axial footprint, allowing for straightforward integration into cramped machinery rooms or existing modular plumbing arrays.
Operational threshold limits are defined by a Max Head 47.7 m alongside a Max Flow 40 L/Min. The assembly integrates a 0.55 kW / 415v motor, ensuring alignment with three-phase industrial site requirements. Consistent hydraulic output is sustained through the 2-pole, short-circuit squirrel-cage motor configuration, which achieves the necessary torque for demanding suction environments. The unit consumes a rated current of 1.32 Amps during peak operation, maintaining structural equilibrium even when subjected to variable load conditions in process water transfer duties.
Fluid dynamics are governed by an AISI 304 stainless steel impeller arrangement housed within a robust, TIG-welded external sleeve design. This structural selection facilitates efficient energy transfer, reducing internal turbulence while protecting the hydraulic integrity of the unit against cavitation stress. The multistage internal geometry allows for progressive pressure generation, meaning that fluid velocity is increased incrementally through each chamber rather than via a single, potentially stressful motion. This mechanical design choice supports the broad liquid temperature tolerance, ensuring that thermal expansion does not compromise internal tolerances.
Protection is provided by a TEFC enclosure rated at IP55 for the motor and IPX5 for the electric pump assembly, which effectively seals the internal windings against common industrial particulates and humidity. The casing is constructed from full AISI 304 stainless steel, offering high resistance to the corrosive potential of stagnant or chemically treated clean water. Mounted with an insulation class F rating, the motor is capable of withstanding ambient thermal stresses up to 50°C. Standardized 25 mm suction and delivery ports allow for flexible connection options using standard threading in various plumbing configurations.
Features:
- TEFC 2-pole squirrel-cage motor with IE3 efficiency class
- Suitable for continuous duty in clean liquid circulation
- Silicon carbide mechanical seal faces for low wear rates
- Certified for potable water transport via WRAS and ACS standards
- PPS technopolymer wear ring for internal clearance control
- IP55 motor ingress protection for humid environments

What maximum water flow rate and discharge port threads apply to this compact booster?
Delivering steady water volume, the 1HM08S05T produces a peak delivery flow of approximately 40 L/Min through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What stainless alloy metallurgy and closed impellers protect this compact booster from corrosion?
Manufactured with durable AISI 304 stainless steel alloys, the 1HM-08S-05T prevents fluid corrosion and abrasive particulate deterioration throughout its stages.
What electrical motor power in kilowatt and full-load current rating apply to this three-phase unit?
Running on an electrical power supply of 380–415 V, 50 Hz, three-phase, the 1HM 08S 05T delivers a motor power rating of 0.55 kW (0.75 HP) at an electrical current of 1.32 A.
Where should this three-phase multistage pump be installed on a level horizontal base for drainage?
Installing the 1HM_08S_05T on a rigid horizontal floor foundation with drainage ensures stability, while a non-return check valve halts backflow.
What maximum dynamic head and vertical lift does this compact multistage pump reach?
Lifting water across steep elevation gradients, the 1HM08S05T achieves a peak dynamic head of approximately 48.3 m.
