Vertical Multistage Pump 80 L/min 64.4m for Boost — Pentax SV-SL-SLX U3-120/6
-
HIGH-EFFICIENCY STAINLESS HYDRAULICS: Features a 6-stage vertical hydraulic assembly with AISI 304 stainless steel impellers, diffusers, shell, and shaft delivering clean water flow up to 80 L/min (4.8 m³/h) with a max head of 64.4 meters (6.44 bar).
-
OPTIMIZED ENERGY SAVINGS: Advanced multi-stage stainless steel impellers divide hydraulic pressure build-up across 6 stages, maximizing output while reducing electrical power draw on 0.9 kW single-phase systems.
-
HIGH-TEMPERATURE TOLERANCE (UP TO 110°C): Capable of handling demanding liquid conditions ranging from +5°C to +90°C (SV version) and -15°C to +110°C (SL and SLX versions) for hot water heating, Boost, and glycol circulation.
-
VERSATILE MATERIAL & PORT OPTIONS: Available in cast iron body with overlapping ports (SV), cast iron body with in-line ports (SL), or 100% full stainless steel AISI 304 body (SLX) for maximum hygienic and corrosion-resistant operation.
-
CONVENIENT 230V SINGLE-PHASE WITH THERMAL PROTECTION: Runs on standard single-phase power with built-in motor thermal overload protection, food-grade EPDM gaskets, ceramic-graphite-EPDM seals, and ceramic-tungsten carbide shaft guiding bushes.
Product information
The Pentax ULTRA SV-SL-SLX Series (models U3SV-120/6, U3SL-120/6, and U3SLX-120/6) represents high-performance, single-phase (230V) vertical multistage centrifugal water pumps engineered for demanding pressure boosting, circulation, and water treatment applications. Built with AISI 304 stainless steel impellers, diffusers, outer casing, and motor shaft, these pumps combine maximum energy efficiency with whisper-quiet, heavy-duty durability.
Powered by a 0.9 kW (1.2 HP) single-phase motor with integrated thermal protection, this 6-stage series delivers up to 64.4 meters of lift head and a maximum delivery flow of 80 L/min. Its compact vertical design optimizes floor space in mechanical rooms and residential utility closets.
Depending on system needs, the series offers versatile configurations: SV (overlapping ports for compact skids), SL (in-line ports for direct piping), and SLX (full AISI 304 stainless steel body for high hygiene standards). With temperature resistance up to 110°C, EPDM gaskets, and ceramic-tungsten carbide intermediate shaft bushes, the Pentax ULTRA SV-SL-SLX 120/6 series is an exceptional Italian engineering choice.
Note: Suitable for clean non-loaded liquids, drinking water, and glycol water mixtures at operating pressures up to 8 bar (≤ 6 impellers).
