Product Overview
The Lowara 3HM02S03T provides efficient and reliable pumping performance. Suction-side fluid handling in small-scale industrial cooling loops relies on the precise, close-coupled orientation of this compact unit. It manages clean, non-aggressive fluids within diverse mechanical assemblies, ensuring steady circulation for systems requiring consistent flow dynamics. The configuration is specifically engineered for installations where space efficiency is as critical as long-term reliability in varying process environments.
Operational parameters are defined by a Max Head 14.6 m and a Max Flow 73.3 L/Min. This performance is generated by a 0.3 kW motor drawing 1.08 Amps, providing the necessary energy to maintain flow stability through 25 mm suction and delivery ports. The unit is calibrated to function effectively within these limits, sustaining hydraulic efficiency under standard operating conditions.
Hydraulic integrity is managed by a multistage arrangement composed of AISI 304 stainless steel components. Fluid enters and travels through the internal channels, directed by precise stage geometry that minimizes turbulence. This design promotes a smooth transition of energy into kinetic force, allowing the assembly to meet demanding circulation requirements with minimal mechanical deviation throughout the service cycle.
Housing the internals is a robust AISI 304 stainless steel body, offering corrosion resistance across its operational temperature range of -10°C to +120°C. The motor is protected by an IP55 rating, while the electric pump assembly itself adheres to IPX5 standards. Mounting is facilitated by a standard foot-base design, which integrates with the unit's 6 kg frame to ensure stability when bolted to structural framing or process skids.
Features:
- TEFC 2-pole squirrel-cage motor configuration for consistent operation
- Class 155 insulation to manage internal thermal loads
- WRAS and ACS certification for compatibility with drinking water loops
- Vibration-dampening feet designed for horizontal mounting configurations
- TIG-welded casing construction for long-term structural integrity
- Silicon carbide mechanical seal components for fluid containment

What peak delivery flow rate does this close-coupled multistage pump provide across plumbing?
Discharge delivery flow peaks at a volume of approximately 73.3 L/Min on the 3HM02S03T, connecting via threaded Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
How does the stainless construction protect this multistage booster from aggressive mineral attack?
All-metal stainless construction ensures the 3HM-02S-03T defends against chemical attack and fluid corrosion using AISI 304 stainless steel throughout.
What kilowatt rating and full-load electrical current draw apply to this three-phase supply pump?
Operating a motor power rating of 0.30 kW (0.4 HP), the 3HM 02S 03T connects to a 380–415 V, 50 Hz, three-phase power feed with an electrical running current of 1.08 A.
How does an in-line check valve prevent reverse flow in this horizontal commercial water pump?
Protection against backflow on the 3HM_02S_03T requires installing an external non-return check valve, with the pump mounted on a horizontal base with drainage.
What peak dynamic head and upward lift capability does this pressure pump maintain?
Vertical fluid lift reaches a maximum dynamic head of approximately 14.9 m through the staged impellers of the 3HM02S03T.
