Product Overview
This compact horizontal multistage centrifugal pump is engineered for demanding small-to-medium commercial environments, providing reliable pressure boosting for heating, ventilation, and air conditioning systems. The 3HM03P04T model addresses the necessity for consistent water movement in cooling circuits and climate control infrastructures. By integrating a precisely manufactured stainless steel 304 hydraulic body with durable technopolymer components, this unit offers a resilient solution for facilities managers and engineers seeking to maintain optimal fluid circulation without the footprint overhead associated with larger, conventional industrial pumping assemblies.
Built for high-performance operation, this unit achieves a maximum capacity of Max Head 31.3 m and Max Flow 70 L/Min. The pump operates on a 0.4 kW / 415v three-phase power input, ensuring reliable energy efficiency through its balanced motor configuration. With 25 mm inlet and outlet connections, the system is designed for straightforward integration into existing pipework, providing stable output and consistent flow rates across diverse duty cycles. Its hydraulic design minimizes internal turbulence, reducing energy consumption and mechanical strain, which promotes sustained long-term operation in intensive service applications.
The e-HM series architecture relies on advanced fluid dynamic principles to achieve its efficiency class, utilizing a TEFC short-circuit squirrel-cage motor coupled with a balanced design to mitigate axial thrust. The internal layout, featuring high-grade stainless steel diffusers and a specialized mechanical seal, ensures the pump remains airtight and free from leakage during periods of continuous operation. This technological foundation provides a reliable barrier against aggressive water properties, maintaining consistent mechanical integrity even when working in temperature-sensitive or high-cycling environments common in modern commercial building management systems.
Designed with practical installation at the forefront, the 3HM03P04T features a compact footprint and standard suction height dimensions for seamless retrofitting in tight plant rooms. The exterior housing is engineered for ease of access, with metric-compliant cable glands and durable fill/drain plugs that simplify routine maintenance and commissioning tasks. Safety is intrinsically managed through a thermal-resistant design, suitable for ambient temperatures up to 50°C, and a protective IPX5-rated assembly that shields the electrical motor against moisture ingress in damp, confined, or semi-exposed installation areas.
Features:
- Compact single-piece fabrication for reduced leakage risk
- IE3 motor technology for energy-conscious performance
- Balanced design minimizes axial thrust on motor bearings
- Drinking water certified components for process safety
- Suitable for continuous duty in climate control circuits
- Standardized metric cable glands for installation flexibility
- Enhanced body thickness for vibration-resistant operation

What metallurgy and mechanical seal materials are engineered into this pump to stop corrosion?
Hydraulic stage materials on the 3HM03P04T combine an AISI 304 stainless steel casing alloy with high-grade technopolymer impellers to safeguard against fluid corrosion and particulate erosion.
What electrical motor power in kilowatt and full-load current rating apply to this three-phase unit?
Motor power on the 3HM-03P-04T is rated at an electrical output of 0.40 kW (0.55 HP), drawing an electrical current of 1.35 A from a 380–415 V, 50 Hz, three-phase power supply.
Where should this three-phase multistage pump be installed on a level horizontal base for proper drainage?
Installation of the 3HM 03P 04T calls for a sturdy horizontal floor base with perimeter drainage, accompanied by an external in-line non-return check valve to stop system backflow.
What dynamic head elevation pressure is achieved by this multistage boosting unit?
Delivering steady vertical lift, the 3HM_03P_04T generates a maximum dynamic head of approximately 34.9 m to propel fluid across high elevation rises.
What water flow volume and suction discharge pipe dimensions are built into this unit?
Water transfer volume reaches a peak delivery flow of approximately 70 L/Min on the 3HM03P04T, connecting via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
