Automatic Transmission Pumps (A/T Pumps)

Automatic transmission oil pumps are used with the Trochocentric gearing system due to low pulsation and low noise behaviour.




  • high displacement using small gear set dimensions
  • very low noise
  • very low pulsation of the oil



These oil pump systems are mainly used in automatic transmissions (A/T). They are used as torque converter oil pumps or they are used as auxiliary oil pumps.
