CHAPTER 6
SYSTEM MAINTENANCE
Proper injection pump maintenance is critical to maintain the service life of the injection pump and system
performance. Perform these maintenance procedures periodically over a season and be sure to store the pump
properly when not being used.
Depending upon the type of chemicals used with the Raven injection system, periodic maintenance may be
required to ensure proper operation of the injection pump.
NOTE:
Some chemicals may require daily maintenance of the injection pump. Review best practices with a
chemical supplier to ensure the proper frequency of pump maintenance.
MAINTENANCE AND STORAGE
Perform the following procedure before storing the injection pump for long periods:
NOTE:
Failure to perform seasonal maintenance may result in damage to injection system or reduce the
service life of the injection pump.
1. Empty product from the chemical supply tank and flush the injection pump with water.
2. Remove hardened chemical residues or build up by flushing the injection system with:
a. kerosene or fuel oil if the last product through the pump was petroleum based.
b. soap and water if the last product through the pump was water based.
WARNING
Always use caution when performing
maintenance or servicing an injection pump or
system which has been previously pressurized.
Wear appropriate protective equipment to
prevent contact with hazardous chemicals and
rinse the chemical system as instructed by the
chemical manufacturer prior to performing
maintenance.
WARNING
Hazardous chemicals may be under pressure
even if the pump has not been in service recently.
Before servicing any components on the injection
pump, thoroughly rinse the injection pump with
clean water to remove excess chemical residue.
