Masten Space Systems and P3 Technologies Team to Offer Line of Electric Pumps

Mojave, CA and Jupiter, FL – July 15, 2019

Masten Space Systems and P3 Technologies have joined forces to offer a line of compact, high power density, high-performance electric pumps.  This collaboration integrates Masten’s proprietary electric motor and controller technology with P3’s advanced pump technology. The first use of this technology is in NASA’s Artemis program, where it is helping return humans to the moon.

The initial product launch, expected in mid-2020, will include pumps for liquid methane, liquid oxygen, and RP for engines in the 5 – 10K pound force thrust class.  This initial introduction will be followed by a liquid hydrogen pump later the same year and additional thrust classes the following year.

“This is a logical commercialization of our development work”, says Sean Mahoney, CEO of Masten Space Systems.  The e-Pump product line is the result of several years of development.  Matt Kuhns, Masten Chief Engineer, adds, “Our e-Pumps enable increased mission capability due to increased system level performance and reduced weight, and they are less costly than turbopumps as well”.  “The e-Pump has several operability advantages over turbine driven pumps in these smaller thrust classes”, added Philip Pelfrey, President of P3 Technologies.  “They don’t have the pressure drop associated with the turbine, and enable rapid engine starts and throttle changes, which are advantageous to in-space and lander propulsion systems”.
