Appendix 4 Pressure Relief
Pressure Rating of Pump Housings and Single-Use Devices
XCell ATF stainless steel pump housings are designed to maximum allowable working
pressure of 45 PSIG at 140
o
C. Stainless steel assemblies are pressure tested (hydrostatic
pressure test at 70 PSI) and marked in accordance with the ASME Boiler and Pressure Vessel
Code.
XCell ATF Single-use devices are designed and validated to withstand a pressure of 60 PSIG
at 40
o
C. All device units are subjected to a pressure hold of 30 PSIG as part of standard
release testing.
Overpressure Relief
To protect the XCell housings and devices from reaching pressures > 40psig, a pressure relief
assembly set at 40 PSIG is located on the outlet of pneumatic box supplying pressure and
vacuum to the air-side hemisphere of the pump housing. The flow path of pressure relief is
shown below.
