Product information
The Pentax ULTRA U5-180/6 is a high-performance Italian multi-stage horizontal centrifugal electric water pump designed for domestic, agricultural, and industrial applications. Built with a heavy-duty AISI 304 stainless steel casing and shaft, it guarantees clean, rust-free water for drinking supply, pressure boosting, heating, cooling, and garden irrigation systems.
Unlike noisy single-stage jet pumps, the U5-180/6 uses a 6-stage multi-stage design with Noryl® impellers that split the pumping workload. This results in smooth, high-volume water delivery (up to 120 L/min) and maximum pressure (up to 66.5 meters / 8.5 bar max pressure) while drawing only 1.5 kW (2 HP) of electricity.
Engineered for safety and versatility, the pump handles liquid temperatures from -5°C to +35°C, making it suitable for both cold water supply and glycol cooling systems. Complete with an aluminum motor bracket for quick cooling, ceramic-graphite-EPDM mechanical seals, and integrated thermal protection on single-phase models, the Pentax U5-180/6 is the ideal energy-saving choice for automatic home pressure systems.
Note: Suitable for clean non-loaded fluids, drinking water, and glycol mixtures at temperatures from -5°C to +35°C. Available in WRAS-approved versions.
