System Operation

IMPORTANT: Remove drive chain from piston pump when fertilizer is not used while planting. This will prevent damage to pump

The liquid fertilizer pumps are single piston, variable stroke pumps. These pumps are ground driven, positive displacement metering devices. Select the high or low rate range. The gallons per acre applied will be accurate regardless of varying ground speeds.

When using the frame mounted single-disk fertilizer opener, a low pressure delivery system is used with a flow divider on the piston pump. The flow divider will automatically adjust for varying application rates and will evenly distribute an equal amount of liquid to each output flow port. The flow divider is self-cleaning of debris; however, should large debris enter the unit, the unit may be cleaned by simply removing the four top socket head screws, then removing the cap, seal, and spring, and finally removing the needle for cleaning with a soft cloth. Assembly is made in reverse order. The unit should be cleaned and flushed out with water after usage to avoid clogging.
