Product Overview
Maintaining circulation stability within demanding liquid processing environments requires specialized materials. The Lowara 3HM03N05M assembly utilizes AISI 316 stainless steel throughout its fluid-contact surfaces to resist degradation when handling aggressive or high-purity media. The compact architecture simplifies integration into cramped industrial footprints while maintaining a rigid structural profile capable of sustained operation in closed-loop systems.
Operational parameters are defined by a Max Head approximately 21.9 m and a Max Flow approximately 73.3 L/Min. Powered by a 0.5 kW single-phase motor, the pump ensures efficient energy conversion for continuous transfer tasks. Performance benchmarks follow strict international hydraulic standards, providing consistent output suitable for temperature control cycles and demanding technical process environments.
Fluid motion is governed by a precision-engineered closed impeller configuration designed to minimize turbulence and optimize internal pressure distribution. This hydraulic design minimizes mechanical vibration and noise, promoting long-term service life for both the seal assembly and internal bearings. The staged construction allows for smooth, incremental pressure increases without excessive axial loading.
Protection is managed through a TEFC motor housing certified to IP55 standards, safeguarding internal electronics against environmental ingress. Mounting relies on a stable base bracket arrangement that minimizes resonance during startup and shutdown cycles. The pump utilizes Rp 25mm inlet and outlet threading for secure, leak-resistant coupling within standard industrial plumbing layouts.
Features:
- Integrated silicon carbide mechanical seals for harsh liquid compatibility
- TEFC motor enclosure with short-circuit squirrel-cage rotor design
- Certified for potable water service under global health standards
- TIG-welded structural components ensuring pressure integrity up to 16 bar
- Corrosion-resistant AISI 316 hydraulic channel construction throughout
- Thermal protection characteristics compliant with standard electrical codes

For facility water boosting, what operating pressure limits and allowable fluid temperatures apply?
High pressure capability on the 3HM03N05M guarantees a maximum working pressure rating of 16 bar (PN 16) alongside fluid temperatures from -30°C to +120°C.
How high does water rise under the maximum dynamic head of this booster unit?
Operating under elevation requirements, the 3HM-03N-05M maintains a peak dynamic head of approximately 21.9 m.
In commercial booster systems, what peak water flow volume and connection diameter are delivered?
Water delivery across plumbing circuits peaks at a flow capacity of approximately 73.3 L/Min on the 3HM 03N 05M through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
Against aggressive fluid contact, what alloy metallurgy and mechanical seals protect this unit?
Guarding against corrosive chemical attack, the 3HM_03N_05M features alloy AISI 316L stainless steel pump casing, diffusers, and closed impellers and elastomeric mechanical seals.
What electrical motor power specifications and operating supply voltage run this multistage pump?
Electrical operation of the 3HM03N05M utilizes a 0.5 kW (0.7 HP) motor powered by 220–240 V, 50 Hz, single-phase pulling 2.48 A.
