The Lowara 1HM11S05M is engineered for residential and light-industrial liquid handling where consistent pressure is required for water transfer and circulation. This horizontal multistage centrifugal pump is designed to handle clean fluids in diverse building service environments, providing a stable flow profile for demanding systems. Its horizontal configuration ensures simplified installation within compact plant rooms or tight utility spaces.
Equipped with a motor output of 0.77 kW / 240v, the system maintains steady hydraulic delivery across its operating envelope. It achieves a Max Head 63.6 m and a Max Flow 40.0 L/Min, providing reliable performance for various pressurized delivery tasks. The suction and discharge ports are sized at 25 mm, allowing for integration into standard residential plumbing networks.
This pump utilizes a multistage architecture to generate pressure efficiently through multiple internal pumping chambers. The hydraulic design promotes flow stability and operational longevity, ensuring the unit remains effective under continuous duty cycles. The internal liquid movement is guided by high-precision stainless steel components, minimizing turbulence and optimizing the energy conversion process during operation.
Built with AISI 304 stainless steel, the pump body is constructed to withstand common operating pressures, ensuring structural rigidity. The unit features an IP55 protection rating for the motor, guarding against environmental moisture and particulates. The TEFC motor arrangement facilitates heat dissipation, while the close-coupled design secures the hydraulic head directly to the motor frame, reducing the overall footprint and maintenance requirements for the end-user.
Features:
- Integrated 2-pole squirrel-cage motor with TEFC cooling architecture
- AISI 304 stainless steel hydraulic construction for fluid compatibility
- Suitable for installation in WRAS and ACS certified clean water systems
- Compact 25 mm threaded suction and delivery port connections
- Asynchronous motor design ensuring consistent operational speeds
- Engineered for fluid temperature ranges between -10°C and +60°C
