Product Overview
Engineered for building services and industrial liquid handling, the Lowara 3HM05S05M serves as a reliable horizontal multistage centrifugal pump designed for systems requiring consistent pressure. It is purpose-built to manage clean water in diverse environments, such as cooling circuits or general process water circulation. The hydraulic configuration ensures steady fluid movement, making it well-suited for applications that demand precise, continuous flow characteristics throughout the facility's plumbing network.
The unit operates with a maximum power output of 0.5 kW at 240v. In terms of hydraulic performance, this model delivers a Max Head 35.2 m and a Max Flow 73.3 L/Min. Its design integrates a 25 mm suction and a 25 mm delivery connection to facilitate straightforward installation within existing pipework. These metrics confirm the pump's capability to maintain required pressure levels while efficiently handling the demands of modern water transfer installations.
Constructed as a horizontal multistage unit, the pump utilizes an AISI 304 stainless steel hydraulic assembly. This material choice is integral to the pump's long-term operational stability and clean water compatibility, ensuring that the internal architecture remains resistant to typical fluid interactions. The multistage arrangement balances the workload across various stages, promoting smooth flow dynamics and reduced vibration during active cycles, which is essential for maintaining system longevity.
The pump is encased in a compact, one-piece stainless steel body, directly coupled to a TEFC motor for effective cooling. The internal sealing uses a single O-ring arrangement to minimize potential leakage points throughout the system's service life. With an IPX5 protection rating for the pump assembly, it is constructed to operate effectively in indoor and protected environments. The unit features high-efficiency motor technology, ensuring optimal energy consumption during routine operation.
Features:
- WRAS and ACS certified components for safe drinking water handling
- Close-coupled motor-pump arrangement to minimize installation footprint
- IP55 rated TEFC motor configuration for electrical environmental protection
- AISI 304 stainless steel hydraulic materials for internal corrosion resistance
- EN 60335-1 and EN 60335-2-41 standards compliance for electrical safety
- Single O-ring casing sealing system for improved leak prevention

What dynamic head capability and fluid lift elevation apply to this booster?
Operating across vertical piping runs, the 3HM05S05M produces a maximum dynamic head of approximately 36.6 m to lift clean water upward.
What fluid flow volume and suction discharge pipe dimensions are built into this unit?
Delivering high fluid volume, the 3HM-05S-05M discharges a peak delivery flow rate of approximately 73.3 L/Min through its Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge.
What materials and mechanical seal elastomers ensure corrosion resistance in this booster?
Constructed with all-stainless metallurgy, the 3HM 05S 05M 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 electrical motor power in kilowatt and full-load current draw apply to this single-phase unit?
Operating on a 220–240 V, 50 Hz, single-phase power supply, the 3HM_05S_05M features an electrical motor power rating of 0.50 kW (0.7 HP) drawing an electrical full-load current of 2.85 A.
Where should this single-phase multistage pump be installed on a level horizontal base for drainage?
Mounting the 3HM05S05M 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.
