Vertical Multistage Pump 1,883 L/min 101m — Pentax U90HS/HX-4000/4-2RT
HIGH-EFFICIENCY MULTISTAGE BOOSTING: Delivers high-volume fluid discharge up to 1883 L/min with a pressure head reach up to 101m for demanding boiler feed.
OPTIMIZED ENERGY SAVINGS: Precision multistage stainless steel hydraulic engineering maximizes flow efficiency to lower kWh electrical power consumption on 30 kW industrial systems.
PREMIUM STAINLESS STEEL: Built for extreme aggressive fluid resistance with a stainless steel pump body, impellers, diffusers, outer shell, and motor shaft.
EXTREME 120°C HIGH-TEMP RATING: Handles fluids from -15°C up to +120°C (up to +85°C for domestic use) and high operating pressures.
SPACE-SAVING IN-LINE VERTICAL DESIGN: Vertical axis with flanged in-line ports allows easy direct piping installation in boiler feed.
Product information
The Pentax ULTRA HX U90HS/HX-4000/4-2RT is an industrial-grade, vertical multistage centrifugal electric water pump engineered for boiler feed and severe industrial pressurization. Designed with a vertical in-line layout, it delivers reliable hydraulic power while taking up minimal space in plant mechanical rooms.
Driven by a 40 HP 30 kW 3-phase 230/400V 50Hz motor, this pump utilizes a full EN 1.4401 / AISI 316 stainless steel hydraulic assembly (pump body, impellers, diffusers, shell, and shaft). Operating at high pressures, it moves up to 1883 L/min with a pressure head of 101m across a temperature span of -15°C to +120°C.
Built for long service life with aggressive liquids, it incorporates a silicon carbide-graphite-EPDM mechanical seal, EPDM body gaskets, a tungsten carbide intermediate bush, and IP55 protection. The Pentax U90HS/HX-4000/4-2RT is the ideal solution for clean, non-loaded fluids and boiler feed.
Note: Suitable for clean non-loaded fluids, drinking water, glycol mixtures, and industrial liquids from -15°C to +120°C.
