Pressure vessel FAQ
TECHNICALQUESTIONS.
What is a pressure vessel?
A pressure vessel is a sealed container that holds a liquid under pressure so it can be delivered in a controlled way. SR-TEK builds them in stainless steel, clear acrylic and toughened glass, from 0.5 to 60 litres, for pressurised fluid dispensing and process applications.
How does a pressure vessel work?
Compressed air is applied above the liquid inside the sealed vessel. The pressure pushes the liquid out through the outlet at a steady, controllable rate, so dispensing stays consistent without a pump. Gauges, regulators and safety components fit to the vessel's ports.
What is the difference between ST, CT and LT series pressure vessels?
ST Series vessels are stainless steel and suit durable, long-term industrial use. CT Series vessels are clear or transparent, so you can see the fluid level and the process itself — ideal for dispensing, monitoring and lab setups. LT Series vessels are built for larger volumes and production support, including food, medical and pharmaceutical environments.
Which outlet and port configurations can a pressure vessel have?
Most SR-TEK vessels can be configured with a top outlet or a bottom outlet, plus multiple ports for inlet, outlet, gauge and safety components. They accept common fittings and dispensing accessories, including valves, gauges, regulators and quick connections.
