Product Overview
Ensuring stable, automatic cooling flow across complex process circuits requires the specialized configuration of the Lowara 3HM05S04T. This horizontal multistage assembly manages the movement of clean liquids within industrial architectures, providing a consistent pressure profile necessary for sensitive process operations. The unit accommodates varying suction conditions, allowing for reliable fluid movement in facilities where maintenance-free circulation is the baseline requirement.
Operational threshold limits for this pump are defined by a Max Head 35.3 m alongside a Max Flow 73.3 L/Min. Powering this output is a 0.4 kW / 415v motor, which maintains steady torque under continuous loading conditions. Designed for mid-range efficiency, the hydraulics ensure consistent throughput even when encountering friction losses typical in extended closed-loop cooling configurations.
Fluid dynamics are governed by a multistage arrangement utilizing precision-engineered AISI 304 stainless steel components to minimize energy dissipation. The pump configuration focuses on high-velocity staging to elevate fluid pressure sequentially, ensuring a smooth delivery curve without the turbulence often found in single-stage alternatives. Internal clearances are kept to a minimum to maintain high volumetric efficiency during operation.
Constructed with an AISI 304 stainless steel casing, the exterior provides chemical resistance suitable for various liquid compositions. The motor is housed within a TEFC enclosure reaching an IP55 protection rating, suitable for indoor plant environments. Installation involves standard 25mm suction and delivery connections, while the internal mechanical seal is formulated to manage standard operating temperatures between -10°C and +120°C.
Features:
- High-efficiency IE3 squirrel-cage motor technology
- Class 155 insulation for thermal management
- TIG-welded casing for structural integrity
- Suitable for continuous process duty cycles
- Standardized 25mm hydraulic threaded connections
- Operating noise profile limited to 55 dB

What horizontal mounting orientation and non-return check valve setup apply to this booster pump?
To stop reverse flow across horizontal pipe runs, an external non-return check valve must be added downstream of the 3HM05S04T on its drained foundation base.
What maximum vertical elevation head does this stainless multistage unit generate?
Fluid elevation pressure generated by the 3HM-05S-04T reaches a peak dynamic head of approximately 36.8 m.
What peak delivery flow rate can this compact multistage pump discharge through its outlet?
Water circulation piping receives a maximum delivery flow volume of approximately 73.3 L/Min from the 3HM 05S 04T via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
How does the stainless steel construction defend this multistage unit against chemical attack?
Manufactured with premium AISI 304 stainless steel materials, the 3HM_05S_04T protects casing and closed impellers against aggressive chemical attack.
What electrical power consumption in kilowatt and motor current feed this large three-phase unit?
Drawing an electrical current of 1.34 A, the 3HM05S04T runs on a 380–415 V, 50 Hz, three-phase power connection with a motor power rating of 0.40 kW (0.55 HP).
