Pulsation dampeners play a critical role in the longevity and efficiency of pumping systems. When industrial applications involve extreme pressures or aggressive chemicals, standard accessories often fall short. Griffco Valve meets these demanding requirements through an exclusive partnership with Fox S.r.l. to distribute their comprehensive line of high-pressure pulsation dampeners. Manufactured in Italy and backed by a reputation for precision engineering, these products expand the capabilities of modern fluid handling systems.
Understanding the Range of Fox S.r.l. Technology
The partnership brings eight distinct technology families to the global market, ensuring a solution for virtually any chemical or hydraulic application. The product line covers an impressive pressure spectrum, ranging from 10 bar up to 20,000 PSI. This versatility allows engineers to select the exact dampener style that fits their specific environmental and performance needs. Whether the system requires a bladder, diaphragm, piston, or bellow design, Fox S.r.l. provides the necessary hardware to mitigate damaging pressure surges.
For applications requiring the highest level of chemical compatibility, the BTHX series utilizes a PTFE elastomeric bellow. This design ensures that the dampener remains resilient even when exposed to the most corrosive fluids. Meanwhile, the BSTX series offers a metallic bellow with zero elastomers, making it the ideal choice for ultra-high temperature or cryogenic services where traditional seals might fail.
Optimized Performance with Fox S.r.l. Bladder Dampeners
The HTRX and HBX series represent the bladder-style offerings within the catalog. The HTRX series features a 316L stainless steel body and remains a favorite for medium to high-pressure scenarios. One of its primary advantages involves the top-repairable design, which allows for field bladder replacement without removing the entire unit from the piping system. This feature significantly reduces downtime and maintenance costs for busy industrial facilities.
Large volume requirements often lead professionals to the HBX series. This bottom-repairable model handles high pressures while providing significant volume capacities. Like many products from Fox S.r.l., these units come with various options, including exotic material bodies and specialized flange connections. Maintaining the proper nitrogen pre-charge remains essential for these gas-charged models. Griffco recommends charging the units to 60–80% of the system working pressure to ensure the best possible protection for the pump and surrounding instrumentation.
Specialized Diaphragm and Piston Solutions
Compact systems often benefit from the HSTX diaphragm series. These units feature an unscrewable body and provide a massive pressure range, with special executions reaching up to 20,000 PSI. The ability to customize the diaphragm material—choosing from options like NBR, EPDM, or Viton—ensures the unit stays compatible with the process fluid. For hydraulic or mineral oil service where cost-effectiveness is a priority, the carbon steel HST series offers a crimped body design that eliminates welds.
When orientation flexibility is a primary concern, the HP piston series and the MPX PTFE flat diaphragm series offer distinct advantages. The HP piston dampeners work in any position, making them perfect for tight mechanical spaces where vertical mounting is impossible. Similarly, the MPX series uses a PTFE flat diaphragm and serves the pharmaceutical and food industries particularly well. These units often feature lapped or electro-polished surface finishes to meet strict hygienic standards. Choosing Fox S.r.l. through Griffco Valve ensures that these specialized configurations are available with the necessary certifications, including ASME U-stamps, CE, and ATEX.
Custom Engineering and International Standards
Every industrial project carries unique challenges, and sometimes a standard catalog item does not suffice. The engineering teams at Griffco and Fox S.r.l. collaborate frequently to design custom “damper lung” configurations for OEM partners and large-scale oil and gas applications. These custom units utilize high-capacity stainless steel or exotic alloys like Inconel and Hastelloy to survive the harshest seawater or brine environments.
Global compliance represents another pillar of this product line. Fox S.r.l. dampeners carry a wide range of international pressure vessel certifications. This includes CRN for Canada, SELO for China, and NR-13 for Brazil, among many others. This commitment to international standards ensures that global companies can standardize their equipment. Specifically across different geographic regions without worrying about local compliance hurdles. By integrating these high-quality dampeners into a system, operators protect their investment and ensure a steady, pulse-free flow. This ultimately improves metering accuracy and prevents pipe fatigue.
