U7S-300/6 All-SS Multistage Water Pump 160l/min 69.9m Air Conditioning
HIGH-EFFICIENCY MULTI-STAGE POWER: Features a 6-stage hydraulic design delivering a strong water flow rate up to 160 L/min (9.6 m³/h) and a max pressure head of 69.9 meters for smooth, reliable water pressure.
ULTRA-LOW ENERGY CONSUMPTION: Driven by an efficient 2.2 kW (3 HP) motor that optimizes power draw to deliver maximum hydraulic output, keeping electricity bills exceptionally low during daily use.
EXTREME TEMPERATURE TOLERANCE (-15°C to +110°C): Handles liquid temperatures from -15°C up to +110°C, making it ideal for hot water systems, heating, air conditioning, cooling, and glycol distribution.
100% STAINLESS STEEL HYDRAULICS: Built for lifetime rust-free, hygienic performance with an AISI 304 stainless steel pump casing, shaft, and stainless steel impellers, paired with food-grade ceramic-graphite-EPDM seals.
WHISPER-QUIET & CERTIFIED QUALITY: Multi-stage impellers divide the workload for smooth, quiet indoor operation. Features WRAS approval availability and integrated motor thermal protection (on 1-phase 230V models up to 1.85 kW).
Product information
The Pentax ULTRA S U7S-300/6 is a premium, all-stainless steel Italian multi-stage horizontal centrifugal electric water pump designed for domestic, commercial, and industrial applications. Built with a heavy-duty AISI 304 stainless steel pump body, motor shaft, and stainless steel impellers, it guarantees 100% rust-free, safe operation for drinking water distribution, pressure boosting, water treatment, and washing systems.
Unlike standard pumps with plastic impellers, the ULTRA S series uses internal stainless steel impellers, allowing it to withstand extreme temperature ranges from -15°C up to +110°C. It handles hot water heating systems, industrial chillers, and glycol cooling circuits effortlessly while running whisper-quietly inside your home or facility.
Engineered to save energy, its 6-stage hydraulic design delivers a high water flow rate of up to 160 L/min and a maximum operating pressure head of 69.9 meters while drawing only 2.2 kW (3 HP) of electricity. Complete with an aluminum motor bracket for fast heat dissipation, EPDM seals, and reliable 1-phase 230V power, the Pentax U7S-300/6 offers unmatched efficiency and durability.
Note: Suitable for clean non-loaded fluids, drinking water, glycol mixtures, and hot/cold liquids from -15°C to +110°C. Available in WRAS-approved versions.
