Product Overview
The Lowara 3HM04P05M compact horizontal multistage centrifugal pump serves as a direct solution for small-to-medium commercial or residential applications where consistent pressure and reliable flow are required. Engineered for cooling, heating, and general water supply, it integrates seamlessly into existing infrastructure to manage liquid circulation tasks. Its specialized design ensures that installers can maintain small footprints without sacrificing system performance or durability in tight plant rooms.
The pump is built with an AISI 304 stainless steel body, balancing structural integrity with cost-effective operation. It operates at a maximum capacity of Max Head 42.4 m and Max Flow 70 L/Min, powered by a 0.55 kW / 240v motor. The unit features standard 25 mm suction and 25 mm discharge porting, simplifying connectivity into standard plumbing configurations while maintaining quiet, stable operation suitable for sensitive residential or commercial environments.
Advanced hydraulic technology within the e-HM series optimizes liquid movement, reducing axial thrust on internal motor bearings to promote longevity. The pump configuration focuses on internal leakage reduction through a single-piece fabricated casing design. It utilizes a precision-balanced technopolymer system that ensures consistent pressure output and efficient fluid delivery, maintaining system stability across a wide range of operational loads.
Designed for versatility, the Lowara 3HM04P05M pump supports continuous duty cycles, provided operating limits are respected. Safety measures include a TEFC motor construction and integrated automatic reset thermal overload protection for the single-phase electrical system. The unit is optimized for easy installation using standard metric piping, ensuring it remains an ideal candidate for retrofitting into established water treatment, washing, or pressure-managed circulation layouts.
Features:
- TEFC electric motor with IP X5 protection rating
- Balanced rotating components to minimize vibration
- Ceramic, carbon, and EPDM mechanical seal configuration
- Suitable for handling moderately aggressive liquid types
- Metric cable gland compliant with EN 50262 standards
- Threaded Rp connection ports for standardized pipe fitting

How should this multistage transfer pump be anchored on a horizontal mounting base with drainage?
Horizontal multistage surface installation on a rigid concrete base is specified for the 3HM04P05M, featuring an integrated setup with proper drainage.
What total dynamic elevation head can this multistage transfer pump achieve under full load?
Operating with multiple hydraulic stages, the 3HM-04P-05M attains a peak dynamic elevation head of approximately 45.5 m under full load.
What water flow capacity and discharge pipe sizes are built into this multistage transfer pump?
Pressure boosting distribution circuits receive a maximum delivery flow of approximately 70 L/Min from the 3HM 04P 05M through its Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge connections.
What materials are utilized in the hydraulic stack to resist mineral attack and particulate wear?
Hydraulic longevity in pressure boosting circuits relies on alloy metallurgy materials in the 3HM_04P_05M, featuring AISI 304 stainless steel pump casing, Technopolymer impellers, and ceramic/carbon/EPDM mechanical seal to prevent fluid corrosion across temperatures from -10°C to +90°C.
What electrical power input and single-phase supply voltage are specified for this multistage pump?
Driving the hydraulic assembly of the 3HM04P05M mandates a 0.5 kW motor input on 220–240 V, 50 Hz, single-phase at 3.34 A, supported by IP55 dust and water spray protection, Class F insulation.
