Product Overview
Navigating complex industrial fluid delivery requirements demands the performance characteristics found within the Lowara 5HM21S30T. This horizontal multistage centrifugal unit offers precise liquid movement, suitable for clean water supply lines, cooling circuits, and high-pressure washing applications. The architecture supports continuous operation in settings where mechanical consistency and precise delivery rates are paramount for system output stability.
Operational parameters are defined by a Max Head 153 m alongside a Max Flow 142 L/Min. The drive system utilizes a 3 kW / 415v motor to maintain hydraulic output under varied load conditions. These specifications ensure that the pump remains a central component for circulation loops requiring specific discharge pressures and reliable fluid throughput.
Internal fluid dynamics are governed by a multistage impeller arrangement crafted from AISI 304 stainless steel. This configuration optimizes the conversion of rotational kinetic energy into fluid pressure, minimizing internal turbulence. The multistage design enables the unit to generate high discharge head while maintaining efficiency, even when handling clean liquids that require steady, non-pulsating flow profiles.
Housing and mechanical components are constructed from AISI 304 stainless steel to maintain structural integrity across the specified temperature range. The assembly features a TEFC 2-pole squirrel-cage motor with an IP55 protection rating, ensuring resilience in demanding environments. Plumbing integration is facilitated through a 32mm suction and 25mm delivery configuration, allowing for secure and simple mechanical attachment in existing piping infrastructures.
Features:
- Integrated IE3 high-efficiency motor architecture
- Silicon carbide and ceramic mechanical seal interfaces
- EPDM elastomer internal sealing components
- IP55 rated motor enclosure for environmental protection
- Designed for continuous operation in process systems
- AISI 304 stainless steel liquid-contact wetted parts

In commercial boosting service, what operating pressure boundaries and fluid temperature are rated here?
Permissible operational boundaries on the 5HM21S30T feature a maximum working pressure capability of 16 bar (PN 16) alongside fluid temperature limits of -30°C to +120°C.
Overcoming vertical elevation rise, what dynamic lift head applies to this pressure booster?
Generating steady upward lift, the 5HM-21S-30T reaches a maximum dynamic elevation head of approximately 153 m.
When circulating clean water, what liquid flow rate and discharge port diameter dimensions apply?
Transferring water across piping networks, the 5HM 21S 30T delivers a maximum delivery flow volume of approximately 142 L/Min via Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge.
How does the pump metallurgy and mechanical seal material selection protect against chemical attack?
Preventing corrosion across internal components, the 5HM_21S_30T utilizes AISI 304 stainless steel pump casing, diffusers, and closed impellers and elastomeric mechanical seals.
What power rating in kilowatts and electrical supply voltage feed run this multistage booster?
Supplying power to the 5HM21S30T, its motor delivers 3 kW (4.0 HP) when energized at 380–415 V, 50 Hz, three-phase drawing 6.31 A.
