Product Overview
Transferring high-purity fluids across industrial cooling architectures requires the chemical resilience found in the Lowara 3HM07N07M AISI 316 stainless steel assembly. Its construction minimizes contact with localized contaminants, ensuring that process water or treated liquids maintain consistent quality standards during transit. Suction and delivery interfaces utilize standardized 25mm connections to integrate into existing pipework configurations without the need for extensive hydraulic modifications.
Operational threshold limits are defined by a Max Head of approximately 50 m alongside a Max Flow of approximately 73.3 L/Min. This centrifugal pump architecture draws a maximum power of 0.75 kW / 240v, sustaining performance throughout continuous cycle applications. System throughput remains consistent under normal load, supported by internal fluid path geometries tuned for efficiency within the e-HM series operational range.
Fluid dynamics are governed by a multistage impeller arrangement engineered to provide progressive pressure elevation across the assembly. Each stage transitions liquid energy through the AISI 316L stainless steel chambers, mitigating internal cavitation risks while maintaining stable circulation profiles. The mechanical design focuses on minimizing turbulence at the transition points between each stage, ensuring a predictable discharge output at high pressure settings.
Housing consists of a TIG-welded external sleeve design, typical of the e-HM sleeve configuration for mid-stage count units, paired with a TEFC electric motor. This enclosure achieves an IP55 protection rating, shielding the motor core from external moisture and airborne particulate intrusion. The unit relies on robust tie-rod mechanical retention to maintain seal integrity across the pump body during thermal expansion and contraction cycles.
Features:
- TEFC motor design featuring IP55 ingress protection
- Internal surfaces composed of corrosion-resistant AISI 316L steel
- TIG-welded external sleeve structural alignment
- Certified for compatibility with potable water systems
- Asynchronous 2-pole motor operating at 2900 rpm
- Synthetic EPDM elastomer sealing components included

What motor kilowatt power rating and electrical supply voltage current feed operate this pump?
Connected to supply power of 220–240 V, 50 Hz, single-phase, the 3HM07N07M operates a 0.75 kW (1.0 HP) motor drawing 4.04 A.
What operating pressure rating and permissible liquid operating temperature limits are specified?
Pressure tolerances on the 3HM-07N-07M certify a maximum working pressure capability of 16 bar (PN 16) with fluid operating limits from -30°C to +120°C.
Across vertical distribution circuits, what peak dynamic elevation head is reached?
Upward vertical propulsion allows the 3HM 07N 07M to maintain a peak dynamic elevation head of approximately 50 m.
How effectively does this pump transfer water volume through its discharge pipe connection?
Discharge fluid delivery peaks at a volume of approximately 73.3 L/Min on the 3HM_07N_07M, plumbed directly to Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What internal metallurgy and elastomeric seal construction prevent corrosion across fluid stages?
Corrosion protection inside the 3HM07N07M is established by AISI 316L stainless steel pump casing, diffusers, and closed impellers and precision mechanical seals.
