Product Overview
Suctionside fluid movement in intensive agricultural environments requires consistent pressure stability provided by the Lowara 3HM19S22T. This multistage configuration addresses the needs of operators managing complex irrigation networks or large-scale liquid transfer cycles. By utilizing a horizontal layout, the assembly maintains a slim footprint while ensuring steady flow continuity throughout long-term operation. Its architecture serves to mitigate turbulence, providing a clear path for liquid entry that is critical for maintaining output consistency in demanding settings where reliable hydraulic performance is expected throughout daily operation.
Operational threshold limits are defined by a Max Head 142 m and a Max Flow 73.3 L/Min. Driven by an IE3 energy-efficient motor rated at 2.2 kW / 415v, the unit balances electrical consumption with necessary mechanical output. The flow dynamics are engineered to handle clean liquids across varied operational windows without significant loss of efficiency, ensuring that pressure remains consistent during periods of high demand while meeting rigorous environmental circulation standards.
Fluid dynamics are governed by a multistage impeller arrangement consisting of AISI 304 stainless steel components that allow for high-pressure generation across small casing dimensions. The interaction between the precision-engineered stages reduces internal drag and maximizes hydraulic energy transmission. The design features a short-circuit squirrel-cage motor configuration, allowing the system to maintain optimal rotation speeds under variable torque conditions. This arrangement supports stable head development across multiple outlet points, ensuring that downstream pressure remains steady despite variations in liquid intake or thermal loading.
Protection is managed via an IP55 rated motor housing and IPX5 rated pump body, shielding internal components from dust ingress and directional liquid sprays. The AISI 304 stainless steel casing ensures structural integrity across a temperature range of -10°C to +120°C, suitable for diverse climatic and processing requirements. Mounted in a horizontal close-coupled fashion, the pump utilizes standard 25mm suction and delivery connections for integration into existing arrays. Insulation Class 155 (F) maintains electrical stability within the motor assembly, preventing thermal degradation during continuous duty cycles.
Features:
- Integrated 2-pole TEFC motor architecture for efficient thermal dissipation
- Class 155 (F) insulation to support long-term electrical safety standards
- TIG-welded casing design providing structural resistance under pressure
- Standardized Rp threaded connections for simplified mechanical integration
- Silicon carbide and EPDM mechanical seal components for leak prevention
- Compliance with ISO 9906:2012 Grade 3B hydraulic precision standards

What peak delivery flow volume does this pressure boosting unit discharge through its outlet?
Discharging clean water into service pipework, the 3HM19S22T provides a maximum delivery flow volume of approximately 73.3 L/Min via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
How do the stainless casing and impellers prevent corrosion and particulate erosion in this booster?
Manufactured with an all-stainless AISI 304 assembly, the 3HM-19S-22T prevents fluid corrosion and chemical attack across all operating stages.
What supply voltage and electrical power rating in kilowatt run this heavy multistage motor?
Electrical motor power rating of 2.2 kW (3.0 HP) on the 3HM 19S 22T requires a 380–415 V, 50 Hz, three-phase power feed drawing an electrical current of 3.91 A.
How does an external check valve prevent reverse flow across this horizontal pressure booster?
Installing the 3HM_19S_22T on a sturdy horizontal foundation base with drainage maintains service life, while a non-return check valve stops reverse flow.
What maximum vertical head and fluid lift capability apply to this booster unit?
Dynamic vertical head reaches a maximum rating of approximately 144 m when running the 3HM19S22T at nominal speed.
