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.

제품 설명

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:

장점 1

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.

이점 2

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.
