Product Overview
The Lowara 1HM20S09M is a precision-engineered horizontal multistage centrifugal pump designed to address demanding pressure requirements in industrial and commercial water handling environments. By utilizing a multistage configuration, this unit ensures consistent flow stability for process water management and system pressure boosting, effectively managing clean liquids within diverse installation settings.
Hydraulic output for this model reaches a Max Head 118 m and a Max Flow 40 L/Min. The unit operates with a 0.95 kW / 240v electric motor, providing high-efficiency performance for continuous operation. The inlet and delivery connections are both 25 mm, ensuring compatibility with standard industrial piping layouts and streamlined liquid circulation.
Built for long-term structural integrity, the pump features a fully fabricated AISI 304 stainless steel hydraulic assembly, including the casing and the internal components. This material choice minimizes risk for corrosion in aggressive environments while ensuring that the wetted parts maintain structural stability under the internal operational pressures generated by the multistage design.
Installation is simplified through a close-coupled arrangement with the TEFC motor, which is protected by an IP55 ingress rating. The pump utilizes a high-grade mechanical seal system to maintain containment efficiency, and the overall construction complies with international standards for both electrical safety and fluid dynamics, ensuring a secure integration into building service systems.
Features:
- TEFC squirrel-cage motor configuration for thermal management
- WRAS and ACS certified materials for potable liquid safety
- Standardized 25 mm suction and delivery port geometry
- Compact one-piece fabricated body construction to reduce leakage
- Premium IE3 efficiency class motor for reduced energy consumption
- AISI 304 stainless steel wetted components for chemical compatibility

What maximum vertical head can this multistage irrigation booster elevate upward?
Operating across vertical piping runs, the 1HM20S09M produces a maximum dynamic head of approximately 117 m to lift clean water upward.
What maximum flow volume can this irrigation multistage pump discharge through its outlet port?
Delivering high fluid volume, the 1HM-20S-09M discharges a peak delivery flow rate of approximately 40 L/Min through its Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
Which stainless alloys are utilized in the casing and impellers to stop fluid corrosion?
Constructed with all-stainless metallurgy, the 1HM 20S 09M combines an AISI 304 stainless steel casing alloy with AISI 304 closed stainless impellers and durable ceramic/carbon/EPDM seal construction to prevent fluid corrosion.
What motor kilowatt rating and electrical voltage supply drive this single-phase booster pump?
Operating on a 220–240 V, 50 Hz, single-phase power supply, the 1HM_20S_09M features an electrical motor power rating of 0.95 kW (1.3 HP) drawing an electrical full-load current of 5.45 A.
How is reverse flow prevented when installing this irrigation booster in a horizontal position?
Mounting the 1HM20S09M requires a rigid level horizontal foundation base with adequate drainage, alongside an external in-line non-return check valve to prevent reverse flow and backflow.
