Product Overview
Complex commercial irrigation setups and large-scale cooling loops demand rigorous mechanical circulation. Engineers specify the Lowara 5HM21N30T multistage centrifugal unit to drive facility utility arrays and manage high-volume fluid transfers across intensive manufacturing zones.
The hydraulic performance establishes an impressive Max Head 153 m combined with a Max Flow 142 L/Min. Operational power depends on a 3 kW drive mechanism functioning purely on a 415v three-phase circuit. Physical pipework relies on exactly 32 mm dimensioning for intake and 25 mm for delivery.
Internal fluid routing is managed through a precisely balanced end-suction hydraulic architecture. This modular multistage configuration heavily limits operational axial thrust, sustaining predictable volumetric displacement and continuous circulation pressure.
High-grade AISI 316 stainless steel forms the entire pump casing and internal stages to resist structural fatigue. Protection systems include an enclosed motor design rated at IP 55, alongside a precise mechanical sealing mechanism defending against fluid bypass.
FEATURES- Fabricated AISI 316 stainless steel compact body structure
- Highly stable closed impeller internal sequence configuration
- Class 155 (F) thermal winding insulation system
- WRAS and ACS compliance for safe drinking water integration
- Essential mechanical seal with reduced O-ring arrangement
- Handles continuous fluid delivery processing up to +120°C
- IP 55 exterior environmental defense rating

Regarding vertical liquid propulsion, what peak dynamic head elevation is delivered?
Vertical discharge pressure from the 5HM21N30T provides a maximum dynamic lift head of approximately 153 m.
For facility water supply, what water delivery flow volume and discharge port dimensions are featured?
Piping networks interface directly with the 5HM-21N-30T across Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge, accommodating a maximum delivery flow rate of approximately 142 L/Min.
How do the stainless construction materials and seal faces ensure corrosion defense in this pump?
Assembled with AISI 316L stainless steel pump casing, diffusers, and closed impellers, the 5HM 21N 30T incorporates mechanical face seals to withstand liquid corrosion.
What electrical motor power and operating supply voltage current feed energize this booster?
Electrical characteristics of the 5HM_21N_30T include a 3 kW (4.0 HP) power rating running on 380–415 V, 50 Hz, three-phase at 10.9 / 6.31 A.
In clean water boosting duties, what maximum working pressure and liquid temperature limits are sustained?
Liquid service boundaries on the 5HM21N30T support a maximum working pressure rating of 16 bar (PN 16) across fluid operating temperature limits from -30°C to +120°C.
