U3SA-90/4 Stainless Steel Multi-Stage Pump 76.7 l/min 13.5m for Clean Water
-
HIGH-EFFICIENCY MULTI-STAGE POWER: Advanced multi-stage horizontal hydraulics deliver a strong water flow rate up to 76.7 L/min (4.6 m³/h) with a maximum pressure rating of 7 bar, making it ideal for home water systems, garden irrigation, and industrial pressure boosting.
-
MAXIMUM ENERGY SAVINGS & QUIET RUNNING: The multi-stage internal design divides the workload across multiple impellers, generating high water flow and steady pressure with minimal power consumption to keep your energy bills low.
-
EXTREME TEMPERATURE RESISTANCE (Up to +110°C): Handles ambient and liquid temperatures from -5°C up to +110°C, allowing safe, seamless operation in hot water systems, heating, cooling, and industrial washing.
-
ALL-STAINLESS STEEL HYDRAULIC CONSTRUCTION: Built with a steel AISI 304 pump body, AISI 304 seal plate housing, and AISI 303 shaft end for 100% rust-free, hygienic performance suitable for drinking water and glycol mixtures.
-
SAFE, RELIABLE ITALIAN QUALITY: Manufactured in Italy with a lightweight aluminum motor bracket, food-grade ceramic-graphite-EPDM seals, and built-in thermal protection (up to 1.85 kW on 1-phase models) to prevent motor overheating (IPX4 rating, Class F insulation).
Product information
The Pentax ULTRA SA U3SA-90/4 is a heavy-duty Italian multi-stage horizontal centrifugal electric water pump designed for domestic, agricultural, and industrial applications. Built with an all-stainless steel hydraulic structure (AISI 304 body and AISI 304 seal plate housing), it provides completely rust-free performance for drinking water distribution, glycol mixtures, water treatment, and HVAC systems.
Unlike standard single-stage pumps, the U3SA-90/4 uses a multi-stage design that boosts water flow up to 76.7 L/min while using significantly less electrical power. A major feature of the ULTRA SA series is its extreme thermal tolerance—operating smoothly in conditions from -5°C to +110°C, making it perfect for both freezing environments and high-temperature washing or heating setups.
Engineered for long, maintenance-free daily service, the pump includes an aluminum motor bracket for efficient heat dissipation, a durable AISI 303 shaft, high-grade ceramic-graphite-EPDM seals, and built-in thermal protection on single-phase models. The Pentax U3SA-90/4 is the ultimate energy-saving, high-temperature pump for home and commercial use.
Note: Suitable for clean water, drinking water, and glycol distribution at temperatures from -5°C to +110°C. Protect from direct weather conditions during installation.
