Product Overview
The Lowara 1HM20N09M provides efficient and reliable pumping performance. Achieving stable hydraulic performance in demanding cooling systems requires the precision engineering of this horizontal multistage unit. Its architecture allows for consistent pressure maintenance across complex pipe circuits while maintaining a compact footprint for tight industrial enclosures. Because the assembly is fabricated from high-grade materials, it excels in applications where fluid purity and structural integrity under stress are the primary concerns for facility operators.
Operational threshold limits are defined by a Max Head 118 m alongside a Max Flow 40 L/Min. Powering this movement is a 0.95 kW single-phase motor, which operates at a rated current of 5.32 Amps to deliver consistent torque under varying back-pressure conditions. These parameters ensure that the hydraulic circuit maintains required velocity and pressure levels to keep critical equipment cooled and properly functioning during peak demand cycles.
Fluid dynamics are governed by a series of high-precision stages, each featuring an AISI 316L stainless steel impeller designed to minimize turbulence and energy loss. The multistage approach allows for significant pressure amplification relative to the footprint, providing a steady, pulse-free discharge stream necessary for sensitive monitoring instrumentation. Internal flow pathways are optimized to reduce friction, allowing the pump to reach its peak head efficiently while maintaining a quiet acoustic profile.
Housing the internals is an AISI 316 stainless steel casing that provides a high degree of protection against corrosive fluids and environmental degradation. The TEFC motor is shielded to an IP55 standard, ensuring isolation from external moisture and airborne particulates. Internally, the setup utilizes robust mechanical seals to prevent leakage, while the shaft is supported by bearings configured for long-term operational stability. The entire unit is mounted to allow for straightforward integration into existing 25 mm plumbing manifolds.

Across facility distribution networks, what peak flow capacity and discharge diameter apply?
Service pipework interfaces with the 1HM20N09M through Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, delivering a maximum flow volume of approximately 40 L/Min.
In rugged fluid environments, what alloy construction and mechanical seal elastomers provide defense?
Corrosion defense throughout the 1HM-20N-09M is delivered by AISI 316L stainless steel pump casing, diffusers, and closed impellers alongside elastomeric mechanical seals.
What electrical power rating and operating line current feed are specified to run this pump?
Connected across a 220–240 V, 50 Hz, single-phase line, the 1HM 20N 09M runs a 0.95 kW (1.3 HP) electric motor at 5.32 A.
Regarding pressure containment, what maximum working pressure rating and temperature limits apply?
Rated for rigorous pressure service, the 1HM_20N_09M provides a maximum working pressure rating of 16 bar (PN 16) across fluid temperatures from -30°C to +120°C.
When pushing liquid upward, what dynamic head elevation does this transfer pump develop?
Vertical pressure development enables the 1HM20N09M to reach a peak dynamic elevation head of approximately 118 m.
