Product Overview
The Lowara 3HM04S03T provides efficient and reliable pumping performance. Suction-side fluid movement in high-precision industrial circuits requires the mechanical consistency offered by this e-HM series unit. This horizontal configuration integrates seamlessly into constrained equipment footprints, facilitating water transport in sophisticated cooling and process-critical environments where stable, vibration-dampened flow remains the primary requirement for sustained operational integrity.
Hydraulic capacity is defined by a Max Head 27.8 m and a Max Flow 73.3 L/Min. Powered by a 0.3 kW / 415v motor, the unit draws a rated current of 1.13 Amps. These performance metrics ensure consistent pressure delivery for varied industrial applications requiring sustained flow rates within standard 25 mm piping infrastructure.
Fluid dynamics are controlled by a multistage arrangement that optimizes internal pressure distribution across the AISI 304 stainless steel components. The design focuses on minimizing turbulence within the casing, allowing for a steady output that preserves long-term seal health even during frequent start-stop cycles common in process automation scenarios.
Protection is managed via an IP 55 rated TEFC 2-pole motor housed for resilience against environmental ingress. The pump features an AISI 304 stainless steel exterior and internals, capable of handling liquid temperatures from -10°C up to +120°C. Mounting is achieved through a standard baseplate, providing a rigid interface for three-phase integration.
Features:
- TEFC 2-pole squirrel-cage induction motor configuration
- Compliance with ISO 9906:2012 Grade 3B hydraulic standards
- Class 155 (F) insulation system for heat management
- Certified for drinking water usage by WRAS and ACS
- Silicon carbide mechanical seal for rotational longevity
- External TIG-welded sleeve construction for pressure containment

What three-phase supply voltage and electrical power rating in kilowatt run this heavy pump?
Electrical supply lines of 380–415 V, 50 Hz, three-phase energize the 3HM04S03T, supporting a motor power rating of 0.30 kW (0.4 HP) at an electrical current draw of 1.13 A.
Where is horizontal foundation mounting recommended for this clean water booster with drainage?
Floor drainage and stability are maintained by anchoring the 3HM-04S-03T horizontally, while an in-line non-return check valve prevents reverse flow.
What peak dynamic head and vertical lift elevation can this clean water pump produce?
Maintaining steady vertical pressure, the 3HM 04S 03T delivers a maximum dynamic head of approximately 29.1 m across pipework.
What maximum water flow volume and discharge pipe connection apply to this supply pump?
Outputting reliable liquid volume, the 3HM_04S_03T achieves a peak delivery flow capacity of approximately 73.3 L/Min through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What stainless alloy metallurgy and closed impellers protect this clean water pump from corrosion?
Hydraulic components of the 3HM04S03T are built with AISI 304 stainless steel alloy metallurgy, preventing fluid corrosion in clean water systems.
