Direct Hydraulic Drive Piston Pump

  • Lower cost and more compact solution for variable rate piston pump drives.
  • Users can supply their own SAE A 2-bolt motor or hydraulic motor/PWM manifold kits are available from John Blue Company. We offer a flow-thru hydraulic motor/PWM manifold kit (116205-91) and a dead-head style hydraulic motor/PWM manifold kit (116205-91D).
  • A piston pump allows for quick and stable adjustment to application rates within millisecond.
  • With a piston pump your application rates won’t change with the temperature.

Manual Rate/Speed Control Drive Kit (Direct Drive)

For remote mounting of drive

  • Can be used for Variable Rate and sectional shut-off as desired.
  • Existing pumps can be easily converted to variable rate.
  • A piston pump allows for quick and stable adjustment to application rates within milliseconds.
  • Motor has 1/2″ NPTF ports to allow connection to any flow control valve.

Variable Rate Hydraulic Drive Kit for Raven, Ag Leader, Trimble (Direct Drive)

(and other systems that can control a PWM Valve)

  • Base kit to add variable rate capacity to a John Blue Piston Pump for PWM (pulse width modulation) series is for Raven, Ag Leader, Dickey-John plus others.
  • Can be used for Variable Rate and sectional shut-off as desired.
  • Existing pumps can be easily converted to variable rate.
  • A piston pump allows for quick and stable adjustment to application rates within milliseconds.
