Product Overview
Engineered for versatility in building services and light industrial environments, this horizontal multistage centrifugal pump is designed to handle clean liquids across varied operational requirements. The 5HM04S05M configuration effectively addresses needs for secondary system boosting, circulation tasks, and process water handling, ensuring consistent hydraulic performance even in space-constrained installations. By integrating the pump body directly with the motor flange, the unit maintains a compact, one-piece footprint while minimizing potential leak points in the hydraulic circuit.
The system achieves a Max Head 27.2 m and a Max Flow 142 L/Min, driven by a 0.5 kW / 240v motor. The hydraulic design utilizes premium AISI 304 stainless steel, prioritizing structural integrity and chemical resistance when processing clean media. Its multistage configuration allows for stable pressure generation suitable for irrigation systems, pressure boosting in multi-storey residential buildings, and closed-loop temperature control setups where consistent fluid movement is essential for operational stability.
Hydraulic efficiency is central to the design, utilizing advanced impeller geometry to optimize flow paths through each of the internal stages. This staging arrangement facilitates high-pressure output without excessive electrical demand, promoting energy-efficient fluid transfer. The pump utilizes a robust shaft assembly that works in unison with the stainless steel internal components to prevent cavitation and reduce vibration, even during sustained operation under maximum load conditions.
Installation is simplified through a close-coupled arrangement that utilizes an IPX5 protection rating, safeguarding internal components from moisture ingress and external debris. Plumbing is accommodated via a 32 mm suction and 25 mm delivery port configuration, providing compatibility with standard piping systems. The TEFC motor design ensures cool operation and consistent duty cycles, making this unit a suitable choice for environments requiring long-term, low-maintenance clean liquid transport.
Features:
- Integrated squirrel-cage TEFC motor with IE3 efficiency classification
- WRAS and ACS certified for safe potable water distribution
- Single O-ring casing sealing architecture for enhanced leak resistance
- AISI 304 stainless steel hydraulic construction throughout
- Enclosed fan-cooled design for consistent thermal dissipation
- Designed for compliance with strict EN 60335-2-41 safety standards

What water flow volume and connection pipe dimensions are engineered into this unit?
Supplying steady fluid flow across piping circuits, the 5HM04S05M 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.
What metallurgy and mechanical seal materials provide corrosion resistance in this unit?
Resisting fluid corrosion and mineral attack, the 5HM-04S-05M utilizes an AISI 304 stainless steel pump body, matching AISI 304 stainless closed impellers, and chemical attack resistant mechanical seal materials.
What electrical motor power in kilowatt and full-load current draw apply to this circulation pump?
Electrical power feed for the 5HM 04S 05M requires a 220–240 V, 50 Hz, single-phase connection, delivering a motor power rating of 0.50 kW (0.7 HP) with an electrical running current of 3.18 A.
Where should this multistage circulation pump be installed on a level horizontal base for drainage?
To prevent reverse flow and maintain line pressure, the 5HM_04S_05M must be paired with an external non-return check valve while anchored securely on a horizontal mounting base with proper drainage.
What maximum dynamic head and fluid lift capability apply to this circulation unit?
Elevating water through vertical supply lines, the 5HM04S05M achieves a peak dynamic head rating of approximately 29.2 m at full elevation push.
