Turnkey Design Services is a leader in the design and development of micro fuel pumps for a wide range of metering applications. Our miniature, lightweight fixed displacement pumps are driven by highly reliable permanent magnet brushless DC motors controlled by "smart" electronics that can be easily modified to fit a particular need.

Our technology is available in two configurations, baseline and smart whereas both configurations contain:

  • A fixed displacement pumping element
  • A "canned" permanent magnet brushless DC motor
  • An electronic control module that:
    • Precisely sets and maintains pump flow
    • Contains protection devices to protect hardware from damage
    • Contains lightning protection and electromagnetic interference circuits

The "smart" pump configuration is capable of:
  • Adjusting motor speed to compensate for fluid temperature viscosity changes
  • Communicating with engine controller to transmit and receive fault and health status
  • Predicting pump remaining useful life

Our micro fuel pump technology provides the following:
  • Good suction performance
  • Contamination resistance
  • Long life
  • Low power draw
  • Constant demanded flow over the entire fluid temperature operating range
  • Fault detection and health monitoring

Technology Currently Available

All Configurations:
  • Powered by 28VDC
  • Receive 4-20 mA Flow Command Signal
  • Pump Heavy Fuels between -40°F to 160°F
  • +/- 2.5% Flow Tolerance
  • EMI and Lightning Protection Circuitry
