Diaphragm pulsation damper HGV

pneumaticstainless steel

Pressure: up to 1379 bar (20.000 PSI) Test Pressure (PT): PS x 1,43 / 1,3 / 1,5 Warranty: see dedicated pageLow maintenance dampeners or better called “low maintenance flow-through suction stabilizer” are typically installed on the suction sides of the API 674 or API 675 and usually combined with spherical resonator BHP series installed in the discharge nozzles. The HGV series is used, instead the standard bladder or diaphragm pulsation dampeners, with clear advantages: 1. Complete customization, as per customers requests and projects specification. 2. The accidental faliure of the bladder / bellow does not compromise the operation since the available liquid volume ensures its proper functionality. 3. It is a dampener useful to stabilize the flow and suction pressures on pumps, where high load losses, high vapor pressure and low NPSHa are present. Construction material can be customized depending on the pumped fluid and end-user specification; as a standard, FOX dampeners are in stainless steel AISI 316 L but materials like: DSS (Duplex Stainless Steel), SDSS (Super Duplex Stainless Steel), Alloy-20, Hastelloy-C and Carbon Steel can be foreseen and painted, as per FOX painting procedure for marine and corrosive environments or as per end-user specification. The elastomer material are available in NBR, HNBR, EPDM, FPM, HYTREL, Butile, Polyurethane, PTFE. Volumes can be customized up to 5.000 liters; FOX is always suggesting to share all the necessary operating conditions, in order to be in a position to select the most appropriate volume for your pump. Process connections (in & out flanges) are customized as per the requirement of the customer,
