Product Overview
The Lowara 1HM08S05M is engineered for diverse liquid transfer duties, including residential water supply, pressure boosting, and small-scale agricultural irrigation. Designed to handle clean fluids across varying head requirements, this multistage unit provides stable pressure delivery. Its horizontal configuration is suited for installations where space-efficient footprint and reliable flow maintenance are essential, allowing for integration into existing pipework systems without extensive structural modifications.
Technically configured for optimal output, this model provides a Max Head 47.1 m and a Max Flow 40 L/Min. The drive system utilizes a 0.55 kW motor operating at 240v, ensuring consistent performance in high-demand scenarios. The hydraulic end is specifically optimized for efficient liquid transport, balancing energy input against sustained pressure output to meet the requirements of modern residential and light commercial water handling environments.
Construction focuses on longevity and mechanical integrity, utilizing high-grade AISI 304 stainless steel for both the pump body and internal liquid path. The multistage design facilitates incremental pressure generation, ensuring smooth operation and reduced turbulence within the hydraulic chamber. This design minimizes internal friction, which contributes to more stable flow rates and reliable performance during continuous operation in demanding water circulation tasks.
This pump features a TEFC motor protected by an IP55 rating, designed to mitigate ingress of moisture and environmental particles during standard operation. Connections utilize 25mm suction and delivery ports, accommodating standard plumbing for straightforward installation. The unit is designed for seamless integration into existing systems, providing a durable solution for automated transfer and boosting tasks without the need for frequent manual intervention or maintenance.
Features:
- AISI 304 stainless steel wetted components for fluid compatibility
- TEFC motor enclosure with IP55 protection rating
- Threaded 25mm suction and delivery port configuration
- Balanced multistage hydraulic geometry for flow stability
- Squirrel-cage induction motor with 3.50 Amps rated current
- Suitable for operating temperatures between -10°C and +60°C

What electrical motor power in kilowatt and full-load current rating apply to this single-phase unit?
Powered by a 220–240 V, 50 Hz, single-phase electrical feed, the 1HM08S05M delivers a motor power rating of 0.55 kW (0.75 HP) at an electrical current draw of 3.50 A.
Where should this close-coupled multistage pump be installed on a horizontal base for proper drainage?
Backflow prevention across horizontal pipe runs requires installing an external non-return check valve immediately downstream of the 1HM-08S-05M, which must rest on a horizontal base with drainage.
What dynamic head elevation capability does this close-coupled multistage unit achieve?
Vertical lift pressure is developed by the 1HM 08S 05M, which maintains a peak dynamic head capability of approximately 47.8 m across its stages.
What water flow delivery rate and pipe connection dimensions are built into this pump?
Plumbing connection lines interface with the 1HM_08S_05M via Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge, discharging a maximum delivery flow volume of approximately 40 L/Min.
What metallurgy and mechanical seal materials ensure corrosion resistance in this supply pump?
Corrosion defense across the 1HM08S05M relies on high-grade AISI 304 stainless steel casing alloys and closed stainless impellers with EPDM elastomers to protect against chemical attack.
