Product Overview
Facilitating consistent fluid displacement across complex industrial cooling loops, the Lowara 5HM03N05M addresses the requirement for reliable liquid management in challenging environments. The horizontal configuration allows for direct alignment within existing mechanical rooms, ensuring that high-purity water handling requirements are met without compromising on space or throughput performance. Installations often benefit from the compact footprint, permitting seamless integration into secondary circuits where thermal management and precise circulation are the primary operational objectives.
Operational threshold limits are defined by a Max Head 20.9 m alongside a Max Flow 142 L/Min. The drive system utilizes a 0.5 kW motor, operating on a single-phase 220-240V supply to maintain energy-efficient movement of fluids. The hydraulic performance adheres to rigorous international standards, providing stability across variable loads while maintaining consistent volume output even under fluctuating suction pressure conditions within the circuit.
Fluid dynamics are governed by a multi-stage, closed-channel configuration, utilizing high-grade internal components to minimize turbulence and energy loss. This arrangement works in tandem with the hydraulic design to achieve steady state flow, reducing mechanical strain on the internal seals during startup sequences. The architecture minimizes vibration, ensuring that the movement of clean liquids remains consistent and quiet during the entirety of the duty cycle.
Constructed with an AISI 316 stainless steel housing, the assembly resists chemical attack and surface degradation over long-term operation. The TEFC motor is rated to IP55 standards, providing full protection against external environmental particles and moisture ingress. Components are mounted using a robust bracket system, while the intake and discharge ports, sized at 32 mm and 25 mm respectively, allow for standard threaded connections that simplify the initial commissioning process and ongoing maintenance.
Features:
- Integrated 2-pole asynchronous squirrel-cage induction motor
- High-resistance AISI 316 stainless steel hydraulic assembly
- IP55 motor protection against airborne dust and moisture
- Compatible with fluids ranging from -10°C up to +60°C
- Suction and discharge ports compatible with standard plumbing
- Engineered for quiet operation in residential or industrial sites

Across connected plumbing lines, what peak delivery flow volume and connection sizing apply to this unit?
Supplying steady fluid flow across piping circuits, the 5HM03N05M provides a maximum delivery flow volume of approximately 142 L/Min with Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge.
Which alloy composition and mechanical seal materials resist corrosion across this booster unit?
Corrosion protection in the 5HM-03N-05M is provided by AISI 316L stainless steel pump casing, diffusers, and closed impellers paired with precision mechanical face seals.
Under standard electrical service, what supply voltage and motor power kilowatt rating are specified?
Electrical power requirements for the 5HM 03N 05M specify a 0.5 kW (0.7 HP) motor running on 220–240 V, 50 Hz, single-phase at 2.80 A.
Under prolonged fluid service, what operating pressure limit and fluid temperature range are supported?
Thermal and pressure boundaries on the 5HM_03N_05M support a maximum working pressure rating of 16 bar (PN 16) alongside liquid temperature tolerances from -30°C to +120°C.
How high can this multistage centrifugal pump elevate water upward across vertical pipework?
Elevating water through vertical supply lines, the 5HM03N05M achieves a peak dynamic head rating of approximately 20.9 m under full push.
