Product Overview
The Lowara 3HM04S05M horizontal multistage centrifugal pump is engineered for demanding liquid transfer tasks within industrial and building service sectors. Designed for high performance in cooling systems and process water environments, this unit ensures stable flow and consistent pressure across varying operating conditions. Its design facilitates efficient suction and delivery, making it a reliable solution for sites requiring continuous water movement in specialized plumbing configurations.
Hydraulic output for this multistage configuration achieves a Max Head 28.7 m and a Max Flow 73.3 L/Min. The motor operates at a maximum power of 0.5 kW / 240v, delivering consistent performance for demanding site requirements. Connections are sized at 25 mm for both suction and delivery, ensuring standard integration with most fluid handling circuits while maintaining hydraulic stability.
Built with precision, the unit utilizes a multistage design to elevate pressure levels progressively through the series. The AISI 304 stainless steel construction provides structural resilience against internal stresses, while the hydraulic assembly ensures optimal fluid movement with minimal vibration. This architectural approach minimizes internal losses, enhancing the longevity of the pump in varied environmental conditions.
Installation is simplified through a close-coupled arrangement where the pump body is connected directly to the motor flange, utilizing a robust seal system to mitigate leakage risks. The unit is protected by an IP55 rated motor with Class 155 (F) insulation, and is suitable for liquid temperatures between -10°C and +60°C, providing versatile deployment in temperature-sensitive water handling applications.
Features:
- Integrated thermal overload protection for 240v motor operation
- AISI 304 stainless steel fabrication for fluid-contact components
- Standardized 25 mm inlet and outlet port geometry
- TEFC 2-pole squirrel-cage asynchronous motor technology
- WRAS and ACS certification for potable water contact safety
- Single-piece casing design to improve structural seal integrity

What horizontal mounting orientation and non-return check valve setup apply to this multistage pump?
Securing the 3HM04S05M in a horizontal orientation on a level foundation base with drainage ensures proper operation, while an external check valve protects the system against reverse flow.
What maximum vertical elevation head does this stainless multistage unit generate?
Lifting clean water upward through elevation rises, the 3HM-04S-05M attains a maximum dynamic head performance of approximately 29.5 m.
What peak delivery flow rate can this compact multistage pump discharge through its outlet?
Discharging through its outlet port, the 3HM 04S 05M delivers a peak water flow rate of approximately 73.3 L/Min utilizing Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
How does the stainless steel construction defend this multistage unit against chemical attack?
Metallurgical materials on the 3HM_04S_05M incorporate an AISI 304 stainless steel pump casing and closed stainless impellers, delivering superior durability against abrasive particulate erosion and corrosion.
What supply voltage and motor power rating in kilowatt drive this single-phase booster?
Electrical supply requirements for the 3HM04S05M comprise a 220–240 V, 50 Hz, single-phase feed, energizing the 0.50 kW (0.7 HP) motor power at an electrical current of 2.64 A.
