Mission-Critical Process Cooling System
The positive displacement pump assembly includes a gerotor type pump element driven by a multi-coil, three phase motor, capable of 460/230 VAC 60 Hz or 380/415 VAC 50 Hz operation, and UL certified for use in R-134a refrigerant. The motor and pump element are contained in a semi-hermetic housing system. Download PDF
Wireline Logging - Sidewall Coring Tool
The hydraulic motor consists of a two piece hollow shaft driven by the keyed IGR and supported by precision ball bearings. Inlet and outlet flow from the supply pump to the motor is routed through internal housing passageways to the IGR element. The motor is equipped with a thrust bearing system designed to minimize impact on the ball bearings. Download PDF
Cryogenic Compressor for Spacecraft Electronic Cooling
The pump supplies oil to seal four pistons used in a multistage nitrogen compressor and lubrication for associated bearing surfaces. The pump contains two independent main circuits each containing an external spur gear-set, filter, and regulator valve. All housings, gearplates, and shafts are manufactured from hardened M4 tool steel. Download PDF
Tracked Military Vehicle Electronics Cooling System
The gerotor pump assembly consists of a rotary type gerotor type pump with an integral electric drive motor and motor control electronics. The drive motor is a permanent magnet, 270 vdc brushless dc design, featuring high energy neodymium magnets, Class H winding insulation, pre-lubricated sealed ball bearings, and an anodized aluminum housing.
