Product Overview
Achieving stable water pressure across multi-storey domestic layouts depends on the precise, consistent delivery found in this multistage configuration. Flow management in sensitive residential or light commercial water circuits benefits from the compact architecture of the 1HM series, which integrates seamlessly into standard piping layouts. By maintaining steady output despite fluctuating line conditions, the Lowara 1HM09S05T assembly serves as an effective solution for pressure-boosting applications where space is at a premium and reliability remains a core requirement.
Operational threshold limits are defined by a Max Head 53.3 m alongside a Max Flow 40 L/Min. The drive system utilizes a 0.55 kW power input rated for 415v supply, ensuring that industrial standards for efficiency are met during continuous operation. These metrics facilitate effective liquid movement across varying elevations, making the unit well-suited for demanding clean water transfer tasks where maintaining specific hydraulic pressure is critical to system performance.
Fluid dynamics are governed by a robust multistage assembly featuring AISI 304 stainless steel construction. This configuration minimizes turbulence across the series of stages, allowing for consistent energy conversion from the motor to the fluid. The internal hydraulic design specifically avoids narrow passages, promoting a smooth flow path that reduces frictional losses. By utilizing high-grade stainless components, the internal structure maintains its geometry even under sustained internal stresses, ensuring the pump retains its efficiency profile over extended usage periods.
Housing and motor protection are defined by an IP55 rating, shielding the electrical core against dust ingress and low-pressure water jets. The unit is fitted with a surface-mounted TEFC, 2-pole squirrel-cage motor capable of operating within diverse environmental temperatures. Mounted on a stable baseplate, the entire assembly is designed to mitigate vibration transmission during startup and operation. The suction and delivery ports are configured for 25 mm connections, providing a secure, leak-resistant interface for industrial plumbing systems.
Features:
- TEFC 2-pole asynchronous motor for continuous load handling
- Class 155 insulation to protect windings from thermal elevation
- IP55 environmental protection rating for external mounting
- TIG welded stainless steel components for maximum structural rigidity
- Suction and delivery ports compatible with 25 mm piping
- Asynchronous short-circuit squirrel-cage rotor configuration

How does the all-stainless construction defend this close-coupled unit against chemical attack?
Stainless alloy metallurgy in the 1HM09S05T combines an AISI 304 stainless steel casing with closed stainless impellers to defend against chemical attack.
What kilowatt rating and electrical supply voltage drive this three-phase multistage motor?
Powered through a 380–415 V, 50 Hz, three-phase electrical connection, the 1HM-09S-05T maintains a motor power rating of 0.55 kW (0.75 HP) drawing an electrical current of 1.36 A.
How does an external check valve prevent reverse flow across this horizontal cooling multistage pump?
Reverse flow prevention on the 1HM 09S 05T relies on an external check valve, installed alongside horizontal mounting on a foundation base with drainage.
What peak vertical lift head can this stainless multistage pump elevate upward?
Driving water through vertical pipework rises, the 1HM_09S_05T delivers a maximum dynamic head of approximately 54.2 m.
What peak fluid delivery volume can this stainless multistage pump discharge across piping?
Discharging into service plumbing, the 1HM09S05T provides a maximum delivery flow volume of approximately 40 L/Min via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
