Product Overview
The Lowara 3HM21N22T is a precision-engineered pump. Industrial pressure boosting applications and specialized water treatment facilities depend on highly reliable liquid handling. Facilities specify this centrifugal multistage pump to support complex automated machinery and safely transfer moderately aggressive fluids across operational zones.
System capabilities establish a Max Head 157 m alongside a steady Max Flow 73.3 L/Min. Electrical input consists of a 2.2 kW motor utilizing a strictly 415v three-phase connection. Physical pipework relies on 25 mm dimensioning for the suction and discharge manifolds.
Internal liquid routing is managed through an efficient end-suction layout designed to minimize mechanical turbulence. The tightly spaced closed impeller series decreases axial thrust, sustaining predictable volumetric displacement and minimizing internal pressure loss during heavy usage.
Forged from full AISI 316L stainless steel, the essential wetted components defend against environmental fatigue. External protection is achieved through an air-cooled squirrel-cage motor enclosure carrying an IP 55 rating, combined with an essential O-ring mechanical seal.
FEATURES- Heavy-duty AISI 316L stainless steel component fabrication
- Axial threaded intake and radial threaded delivery pathways
- Motor winding insulation rated to Class 155 (F)
- Potable water approved via WRAS and ACS certifications
- Operating temperature threshold from -10°C to +120°C
- Specialized mechanical seal with reduced O-ring arrangement
- IP 55 exterior physical protection rating

What electrical motor power specifications and supply voltage current feed power this booster?
Operating from an electrical line of 380–415 V, 50 Hz, three-phase, the 3HM21N22T features a 2.2 kW (3.0 HP) motor pulling 7.15 / 4.13 A.
What maximum working pressure capability and permissible fluid temperature range protect this unit?
Pressure service boundaries on the 3HM-21N-22T certify a maximum working pressure limit of 16 bar (PN 16) with fluid temperatures from -10°C to +120°C.
Across vertical distribution risers, what dynamic head does this booster unit deliver?
Hydraulic vertical propulsion enables the 3HM 21N 22T to reach a peak dynamic head of approximately 157 m.
What maximum water flow volume and discharge pipe outlet diameter are engineered into this unit?
Integrating into piping systems with Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, the 3HM_21N_22T outputs a maximum delivery flow volume of approximately 73.3 L/Min.
What alloy composition and mechanical seal construction ensure corrosion resilience across this unit?
Structural metallurgy throughout the 3HM21N22T combines AISI 316L stainless steel pump casing, diffusers, and closed impellers with mechanical face seals for corrosion defense.
