The FOX MPX Series Flat Diaphragm Pulsation Damper is an advanced technical solution for damping pulsations within complex hydraulic and process systems<\/span><\/span>. <\/span>The device body is entirely made of AISI 316 L stainless steel, a material selected to provide significant corrosion resistance and long-term reliability<\/span><\/span>. <\/span>The internal flat diaphragm is made of PTFE, known as Teflon, ensuring excellent chemical compatibility and consistent performance even under repeated mechanical stress<\/span><\/span>. <\/span>The accumulator installation is extremely versatile, as it is designed to operate effectively in any spatial position<\/span><\/span>. <\/span>The standard integrated nitrogen valve features a unified 5\/8″ UNF connection<\/span><\/span>.<\/span><\/p>\n

Operating Principle and Mechanical Life<\/h3>\n

To ensure optimal use as a pulsation damper, the nitrogen pre-charge pressure must be accurately calculated, strictly falling within a range between 60% and 80% of the actual working pressure<\/span><\/span>. <\/span>This value must be determined by carefully considering the type of pump used in the circuit and the operating temperatures of the fluid<\/span><\/span>. <\/span>The mechanical life of the component depends directly on the operating conditions, as the number of operating cycles is inversely proportional to the increase in the compression ratio<\/span><\/span>. <\/span>The maximum working pressure supported under operating conditions, indicated as PS, is 150 bar, while the test pressure PT is calculated by applying international standard coefficients, equal to PS multiplied by 1.43, 1.3 or 1.5<\/span><\/span>.<\/span><\/p>\n

Dimensional and Volumetric Specifications<\/h3>\n

The models in the range differ in structural dimensions and volumetric capacities, allowing precise sizing for various industrial contexts<\/span><\/span>. <\/span>Overall heights range from 205 millimetres for the most compact model, with a capacity of 1.5 litres, up to 470 millimetres for the 12-litre version<\/span><\/span>. <\/span>The external diameter is maintained at 200 millimetres for the smaller models, while it reaches 300 millimetres for variants from 5.5 litres upwards<\/span><\/span>. <\/span>The hydraulic connection includes female BSP threaded ports of one and a half inches for the smaller models and two inches for dampers with larger volumes<\/span><\/span>. <\/span>The structural weight scales proportionally, starting from 35 kilograms and reaching 110 kilograms in the largest format<\/span><\/span>. <\/span>The maximum permitted nitrogen pre-charge is set at 105 bar for the entire MPX series<\/span><\/span>.<\/span><\/p>\n

Customisations and Construction Variants<\/h3>\n

The series offers extensive configuration options to meet specific design requirements. <\/span>The body can be externally painted according to standard FOX procedures or specific technical directives<\/span><\/span>. Connection options extend to SAE 3000, SAE 6000, ANSI B16.5 and UNI\/DIN flanges, as well as API spec. <\/span>6A type 6BX, Autoclave, Grayloc and integrated flanges<\/span><\/span>. <\/span>Versions for handling pressures higher than the standard ones, constructions in exotic materials or carbon steel, and special volumes based on requested sizing are available<\/span><\/span>. <\/span>For the food and pharmaceutical sectors, the device can be equipped with an FDA-certified flat diaphragm and a lapped or electropolished version<\/span><\/span>. <\/span>A single double-diaphragm configuration is available for in-line fluid passage, as well as a sandwich double-diaphragm version integrated with a rupture detector managed through a pressure switch, pressure transmitter, pressure gauge or small piston<\/span><\/span>.<\/span><\/p>\n

Certifications and International Standards<\/h3>\n

Upon explicit request, the component can be manufactured and tested in full compliance with multiple international regulations. <\/span>These include CE PED and ATEX directives, ASME VIII Div.1 or Div.2 standards with U-Stamp and NB, EN 14359, EN 13445 and PD5500<\/span><\/span>. <\/span>The list also extends to territorial certifications for global export, such as KOSHA, SELO, CU-TR, DOSH, NR-13 and CRN, as well as technical approvals from naval registers and bodies such as BV, DNV\/RINA, Lloyd’s and ABS<\/span><\/span>.<\/span><\/p>\n
