Product Overview
The Lowara 5HM12S22T provides efficient and reliable pumping performance. Navigating complex fluid delivery requirements within industrial process settings relies on the resilient mechanics of this horizontal multistage unit. Its architecture facilitates seamless integration into fixed piping networks, serving high-demand circulation tasks where consistent pressure head is non-negotiable. Whether managing cooling loops or secondary supply networks, the device maintains volumetric stability under continuous load, ensuring operational flow continuity throughout the day.
Operational performance thresholds are defined by a Max Head 88.3 m alongside a Max Flow 142 L/Min, driven by a 2.2 kW / 415v motor configuration. These performance metrics allow for precise fluid movement, minimizing energy waste while maximizing system throughput. The integration of high-efficiency hydraulic components ensures that the energy-to-output ratio remains within strict operational parameters suitable for modern facility standards.
Fluid dynamics are governed by a multistage stainless steel assembly that promotes laminar flow and reduces internal friction losses. The design focuses on the kinetic energy transfer through precisely engineered channels, which, combined with the 2-pole squirrel-cage motor technology, delivers steady, vibration-dampened output. Internal components are built to resist wear, supporting long-term reliability in handling clean process liquids across varied suction and discharge conditions.
Constructed from AISI 304 stainless steel, the casing provides significant resistance to internal and external stresses. The assembly features an IP 55 protection rating for the motor and IP X5 for the pump unit, isolating electrical components from moisture. Installation is simplified through standardized G 1 1/4 suction and G 1 discharge connections, allowing for direct integration into existing plumbing infrastructures, complemented by an insulation class 155 (F) system.
Features:
- Certified for drinking water compatibility by WRAS and ACS standards
- Equipped with a high-efficiency IE3 squirrel-cage motor configuration
- Designed for operational liquid temperatures between -10°C and +120°C
- Utilizes a technopolymer PPS wear ring for increased hydraulic tolerance
- Includes silicon carbide and EPDM mechanical sealing components
- Compact two-pole induction drive suitable for continuous duty cycles

How much electrical motor power in kilowatts and what supply voltage feed are required here?
The electric motor on the 5HM12S22T delivers 2.2 kW (3.0 HP) powered by 380–415 V, 50 Hz, three-phase with a rating of 3.94 A.
In terms of fluid limits, what permissible temperature range and maximum operating pressure govern this unit?
Liquid thermal limits on the 5HM-12S-22T span from -30°C to +120°C, backed by a maximum working pressure rating of 16 bar (PN 16).
Which dynamic head elevation capability is developed by this stainless steel booster pump?
Vertical lift pressure is developed by the 5HM 12S 22T, which maintains a peak dynamic head of approximately 88.3 m across its multistage impellers.
How much fluid flow volume and what discharge plumbing port diameter does this booster provide?
Plumbing connection lines interface with the 5HM_12S_22T via Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge, discharging a maximum delivery flow volume of approximately 142 L/Min.
How do the casing metallurgy and elastomer seal construction resist chemical attack and corrosion here?
Structural metallurgy on the 5HM12S22T utilizes AISI 304 stainless steel pump casing, diffusers, and closed impellers, complemented by mechanical seals to withstand corrosion.
