Stark Commercial High-Flow 4 NPSM Pressure Vessel Series
The Stark commercial **4 NPSM pressure vessel** features a wide threaded top opening engineered for high-flow industrial water treatment. This heavy-duty tank eliminates pressure drop bottlenecks and is fully compatible with 1.5″ to 2″ control valves, making it ideal for large-scale boiler feed and hotel water systems.
Product Beschrijving
The Industrial Workhorse: High-Flow 4 NPSM Pressure Vessel.
The Stark **4 NPSM pressure vessel** series is designed to meet the rigorous demands of high-volume commercial and industrial applications. As vessel diameter increases (14″ to 36″), standard openings create a “choke point” that restricts flow. Our 4″ NPSM design solves this by providing a significantly larger cross-sectional area, allowing for higher service flow rates and vigorous backwashing of heavy media.
Constructed with a thickened fiberglass winding layer over a seamless PE liner, these tanks offer superior structural integrity to handle the immense weight of large media beds while maintaining a 150 PSI pressure rating.
Engineering Data:
Large-diameter vessels require strict fatigue analysis to ensure safety under load. For cycle pressure test reports, resin loading calculations, and dimensional drawings, please reference the official technical data at our specialized manufacturing division:

Voordeel één
Maximized Flow & Low Pressure Drop
The 4″ NPSM top opening is a critical upgrade for commercial systems. By pairing with 1.5″ or 2″ control valves, this series minimizes pressure drop during service flow and ensures sufficient water velocity for backwashing. This is essential for heavy media beds (like Pyrolox or Greensand) that require vigorous expansion to prevent fouling, ensuring your system operates efficiently for years.Voordeel TWEE
Heavy-Duty Structural Integrity
Larger tank diameters require superior structural reinforcement. Stark 4″ NPSM vessels feature a thickened fiberglass winding layer and a reinforced base design to withstand the static load of tons of filter media. Rated for 150 PSI (10.5 Bar) and cycle-tested for fatigue resistance, these tanks are built to perform reliably in harsh industrial plant environments.Verwante producten

FAQ
V1: Hoe lang gaat het omgekeerde osmose systeem mee?
De levensduur van een omgekeerd osmose systeem hangt af van de waterkwaliteit en het onderhoud. Het membraan gaat meestal 2-3 jaar mee, terwijl het systeem zelf meer dan 10 jaar kan meegaan als het goed onderhouden wordt.
V2: Kan het systeem worden aangepast aan verschillende wateromstandigheden?
Ja, al onze systemen zijn volledig aanpasbaar. We analyseren uw waterrapport en toepassingsbehoeften voordat we oplossingen op maat bieden.
V3: Aan welke normen voldoet de apparatuur van STARK?
Onze producten voldoen aan CE, ISO 9001 en kunnen op verzoek worden ontworpen om te voldoen aan specifieke regionale voorschriften of industrienormen.
V4: Wat is de levertijd voor STARK RO-systemen?
Standaardsystemen worden binnen 7-15 dagen verzonden. Voor aangepaste bestellingen kan de levertijd oplopen tot 20-25 dagen, afhankelijk van de complexiteit.
V5: Biedt u technische ondersteuning of begeleiding bij de installatie?
Ja. We bieden volledige technische documentatie, begeleiding op afstand via video en kunnen op verzoek technici internationaal sturen.
V6: Wat is inbegrepen in jullie offerte?
Onze offerte omvat het volledige RO-systeem, het bedieningspaneel, de pompen, de voorbehandelingsunits en alle benodigde appendages. Installatiegereedschap en reserveonderdelen kunnen op verzoek worden meegeleverd.
