Product Overview
The Lowara 5HM03S05M provides a dedicated solution for pressure boosting and industrial liquid handling. Engineered for professional building services, this horizontal multistage centrifugal pump is designed to maintain consistent flow in systems requiring precise pressure management. Its configuration is particularly suited for cooling circuits and process water transport where consistent mechanical output is necessary to sustain operational continuity in diverse facility environments.
Hydraulic performance is defined by a Max Head 20.9 m and Max Flow 142 L/Min. The unit incorporates a 0.5 kW motor, operating efficiently to manage clean water volumes. With suction connections at 32 mm and delivery at 25 mm, the pump is built for standard infrastructure integration, ensuring steady liquid delivery across various stages of the application cycle while meeting stringent technical requirements for mid-scale transfer duties.
Construction focuses on longevity and hydraulic efficiency through the use of AISI 304 stainless steel for both the main pump body and internal liquid path components. The multistage geometry is optimized to ensure stability and low-vibration operation, even during constant duty cycles. By utilizing high-grade stainless steel throughout, the pump minimizes fluid friction and provides excellent resistance against common liquid-related wear over extended service intervals.
Designed as a close-coupled unit, the assembly is compact and features a TEFC motor arrangement rated for protection up to IPX5 as an integrated pump set. The electrical system utilizes a 240v input with thermal overload considerations standard to the e-HM series configuration. Installation remains straightforward due to the standard threaded porting, facilitating easy connection to existing pipework in mechanical rooms or skid-mounted configurations.
Features:
- Integrated AISI 304 stainless steel hydraulic components
- TEFC motor enclosure rated for IPX5 liquid protection
- Designed for fluid temperatures between -10°C and 60°C
- Threaded Rp suction and delivery port configuration
- Engineered for high-efficiency operation in 50Hz networks
- Single-piece body design with high-integrity O-ring sealing

What peak vertical elevation head is produced by this cooling multistage pump?
Operating across vertical piping runs, the 5HM03S05M produces a maximum dynamic head of approximately 22.1 m to lift clean water upward.
What peak fluid delivery volume can this multistage cooling pump discharge through its outlet?
Delivering high fluid volume, the 5HM-03S-05M discharges a peak delivery flow rate of approximately 142 L/Min through its Rp 1-1/4" (32 mm) suction and Rp 1" (25 mm) discharge.
How does the all-stainless construction defend this cooling pump against chemical attack?
Constructed with all-stainless metallurgy, the 5HM 03S 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 supply voltage and motor power rating in kilowatt drive this cooling multistage motor?
Operating on a 220–240 V, 50 Hz, single-phase power supply, the 5HM_03S_05M features an electrical motor power rating of 0.50 kW (0.7 HP) drawing an electrical full-load current of 2.80 A.
What horizontal mounting orientation and non-return check valve setup apply to this cooling pump?
Mounting the 5HM03S05M 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.
