The Schneider Electric PNV-2 Diaphragm Pressure Vessel is a versatile and reliable solution for storing and transferring various gases and liquids in industrial applications. This diaphragm pressure vessel is designed and manufactured in accordance with the European Pressure Equipment Directive (PED) and the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, ensuring the highest standards of safety and quality.
The Schneider Electric PNV-2 Diaphragm Pressure Vessel features a corrosion-resistant, fiberglass-reinforced polyester (FRP) tank with a seamless, elastomeric diaphragm as the containment boundary. This innovative design eliminates the need for a traditional welded tank and associated metallic parts that can be susceptible to corrosion and leaks. The diaphragm is made of a high-performance elastomer, such as EPDM or PTFE, providing excellent chemical resistance and flexibility.
The vessel is available in various sizes, from 30 to 1,500 gallons (113 to 5,677 liters), and can be configured with different options, such as temperature controls, pressure relief devices, and level indicators, depending on the specific application requirements. The PNV-2 Diaphragm Pressure Vessel can operate at pressures up to 150 psi (1,034 kPa) and temperatures ranging from -40 F to 300 F (-40 C to 149 C).
The Schneider Electric PNV-2 Diaphragm Pressure Vessel is easy to install and maintain, as it requires no internal welding or metal parts that could potentially cause leaks. The diaphragm can be easily inspected and replaced without the need for extensive downtime or specialized tools. The vessel is also lightweight and portable, making it ideal for applications where space and weight are critical factors.
With its robust design, superior material selection, and easy maintenance, the Schneider Electric PNV-2 Diaphragm Pressure Vessel offers unmatched reliability and longevity, making it a preferred choice for industrial applications that demand safe, efficient, and cost-effective gas and liquid handling solutions.
Schneider Electric's PNV-2 diaphragm pump is a popular choice for various industrial applications due to its robust design and efficient performance. However, like any other equipment, it comes with its own set of advantages and disadvantages.
