PMD Tanks

Propellant Management Device (PMD) tanks are used in mono- and bi-propellant systems for the control of fluid and separation of the pressurant gas from the fuel or oxidizer to provide gas-free propellant to the thrusters through the spacecraft life. Northrop Grumman presently manufactures PMD tanks with over 100,000 cubic inches of volume with numerous PMD designs for specific mission applications. We have fabricated PMDs for manned and unmanned space missions traveling in low-Earth and geosynchronous orbits as well as deep space. Our versatile propellant management solutions enable complex multi-task missions. The all-titanium PMD tanks assure long-term propellant compatibility throughout mission life. We have delivered 1,200 PMD tank assemblies to date.
