Environmental System Support Aboard the International Space Station (ISS) | Leading Supplier of Spacecraft Environmental Systems
Benefits & Features
This ceramic spur gear pump was designed to allow variants to support three environmental systems on the ISS: oxygen generation (OGA system), water delivery (WPDP system), and waste water processing (WWP system). The highly engineered solution provides the exceptional reliability and long operating life required of space-based equipment; service calls are problematic. Designed with common parts and processes these pumps featured:
- Zirconia pump gears
- Stellite drive shafts
- Ceramic side plates
- 316 stainless steel housings
- Silicon-carbide journal bearings
- Complete traceability and documentation to support NASA program standards
- Zero-G operation
This ECLSS NASA Fact sheet provides an overview of the system which is located on Node 3 of the ISS.
