Product Overview
The Lowara CO350/03 is engineered for professionals requiring reliable liquid movement in civil and industrial environments. This unit serves as a primary solution for process water handling, specifically designed to manage clean or slightly contaminated fluids containing suspended solids. Its build ensures steady operation in demanding settings where corrosion resistance is essential, providing a stable flow for cooling circuits and industrial washing systems.
Built with high-grade AISI 316L stainless steel, this pump features a maximum capacity of Max Head 6.8 m and Max Flow 250 L/Min. The drive system utilizes a 0.64 kW / 415v three-phase motor, optimized for continuous duty. The plumbing configuration requires 40mm inlet and 32mm outlet connections, ensuring integration with existing hydraulic infrastructure while maintaining an 8 bar pressure tolerance.
Technological precision defines the CO series, utilizing an open impeller design that allows for the passage of solids up to 11 mm without clogging. The close-coupled architecture reduces the physical footprint, while the TEFC asynchronous motor provides efficient, externally ventilated performance. Thermal stability is maintained across a broad temperature range of -10°C to +110°C, supported by FKM elastomers.
Installation is streamlined through standard Rp threaded connections. The unit is protected by an IP55 rated enclosure, ensuring durability against dust and moisture ingress. Users should note that three-phase models require external overload protection. The robust galvanized steel support foot secures the assembly, minimizing vibration and ensuring alignment during long-term service cycles in industrial applications.
Features:
- AISI 316L stainless steel seal housing and shaft extension for chemical resistance
- Carbon/Ceramic mechanical seal faces standard for extended wear life
- Compatible with a wide range of process liquids up to 110 degrees Celsius
- Galvanized steel support base designed for simplified mounting and vibration reduction
- IP55 protection rating against dust and low-pressure water jet ingress
- Hydraulic performance testing according to ISO 9906:2012 Grade 3B standards

Where is horizontal surface mounting recommended for this open-impeller transfer unit with drainage?
Surface floor mounting on a horizontal rigid foundation base is recommended for the CO350/03, installed with an integrated layout and proper floor drainage.
What total dynamic head is produced by this open-impeller industrial transfer unit?
Circulating liquids with suspended particulates, the CO350-03 achieves a maximum dynamic head of approximately 9.5 m across its operating curve.
What peak delivery flow volume and connection port threads apply to this open-impeller transfer unit?
Open-impeller fluid transfer is powered by the CO 350 03, discharging a maximum water flow rate of approximately 300 L/Min via Rp 1-1/2" (40 mm) suction and Rp 1-1/4" (32 mm) discharge ports.
What metallurgy and open impeller construction allow this industrial pump to transport suspended solids?
Suspended solids passage and corrosion defense rely on alloy metallurgy materials in the CO_350_03, featuring AISI 316L stainless steel casing and open impeller, with ceramic/carbon/FPM mechanical seal capable of managing suspended solids up to 11 mm in diameter.
What electrical power and three-phase supply voltage drive this open-impeller transfer unit?
Driving the rotating assembly of the CO350/03 relies on a 0.37 kW motor on 380–415 V, 50 Hz, three-phase drawing 1.46 A, featuring IP55 dust and water spray protection, Class F insulation.
