Product Overview
Designed for residential pressure boosting and light commercial transfer, the Lowara 1HM04P05M horizontal multistage pump provides a quiet, stable solution for clean water circulation. It is engineered to resolve low-pressure issues in domestic supply lines, household irrigation, and filtration setups, ensuring steady delivery.
Powered by a 0.5 kW / 240v single-phase motor drawing 2.90 A, the Lowara 1HM04P05M unit delivers peak metrics of Max Head 39.3 m and Max Flow 40 L/Min. These precise hydraulic parameters delivers optimal energy conversion, providing consistent pressure for multi-tap domestic setups or washing systems.
The hydraulic core is housed within a thick AISI 304 stainless steel casing, paired with high-grade Technopolymer impellers for high wear resistance. This balanced hydraulic design minimizes axial thrust, facilitating smooth operation while extending the motor bearing lifespan.
Installation is simplified by the compact footprint featuring 25mm inlet and 25mm outlet connections. With IP X5 electrical protection and built-in thermal overload protection featuring automatic reset, this unit is fully prepared for continuous, safe outdoor or indoor operation.
Features:
- Certified under WRAS and ACS standards, ensuring full approval for drinking water applications and hygienic domestic use.
- Engineered with a single O-ring casing design that reduces potential leakage pathways during continuous operation.
- Utilizes a Totally Enclosed Fan Cooled motor with external ventilation to maximize heat dissipation during cycles.
- Features a pump body thickened by twenty percent to withstand heavy-duty operating stresses and physical demands.
- Class 155 F motor insulation provides thermal tolerance, preventing winding degradation under heavy loads.
- Accommodates liquid temperatures up to sixty degrees Celsius, making it versatile for diverse fluid transfer duties.
- Verified to ISO 9906:2012 Grade 3B standards, confirming strict manufacturing quality and flow tolerances.

What horizontal mounting orientation is specified for this multistage irrigation pump?
Horizontal multistage surface installation on a rigid concrete base is specified for the 1HM04P05M, featuring an integrated setup with proper drainage.
What peak dynamic head can this multistage irrigation pump achieve across piping runs?
Operating with multiple hydraulic stages, the 1HM-04P-05M attains a peak dynamic elevation head of approximately 44.0 m under full load.
What peak delivery flow volume can this horizontal multistage irrigation pump provide through its outlet?
Pressure boosting distribution circuits receive a maximum delivery flow of approximately 40 L/Min from the 1HM 04P 05M through its Rp 1" (25 mm) suction and Rp 1" (25 mm) discharge connections.
How do the stainless steel casing and polymer impellers defend this irrigation pump from chemical attack?
Hydraulic longevity in pressure boosting circuits relies on alloy metallurgy materials in the 1HM_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 motor kilowatt power and single-phase electrical feed are required for this irrigation pump?
Driving the hydraulic assembly of the 1HM04P05M mandates a 0.5 kW motor input on 220–240 V, 50 Hz, single-phase at 2.90 A, supported by IP55 dust and water spray protection, Class F insulation.
