Product information
The Pentax ULTRA SLG / SLXG U3SLG-450/20T (and U3SLXG-450/20T) is a commercial-grade, vertical multistage centrifugal electric water pump engineered for high-pressure boiler feed, HVAC circulation, food-grade liquid distribution, and water treatment facilities. Designed with a vertical in-line layout, it provides maximum pressure output while occupying minimal floor space.
Driven by a 3 kW (4 HP) 3-phase 230/400V motor, this 20-stage pump utilizes all-stainless steel AISI 304 impellers, diffusers, outer shell, and motor shaft. Operating at pressures up to 25 bar, it delivers a flow rate up to 80 L/min across a wide temperature range of -15°C to +110°C.
Built for maximum durability in extreme environments, the pump incorporates a graphite-tungsten carbide-EPDM mechanical seal, EPDM gaskets, and an advanced ceramic-tungsten carbide intermediate shaft bush to prevent vibration across high stage setups. With IPX5 waterproofing and Class F insulation, the Pentax U3SLG/SLXG-450/20T delivers exceptional reliability for heavy-duty industrial systems.
Note: Suitable for clean non-loaded fluids, drinking water, glycol mixtures, and hot water systems from -15°C to +110°C.
