2. RECOMMENDED INJECTION PUMP FLUSH SYSTEM
The recommended system is shown in Figure 10. Strainers are recommended for the product
and flush system water. Strainers suitable for concentrated product are typically 20 mesh
stainless steel. However, certain products may not flow through strainer without causing
excessive vacuum or may clog strainer entirely. It is recommended that a flush system be
incorporated with the injection system. This will enhance the performance of the injection pump.
The basic components are shown below and are available through local spraying equipment
supplier. This system shall be installed as shown and operated per the following instructions.
The required frequency of flushing may vary per the product being injected.
1) Drain or empty Product Injection Tank.
2) Place VALVE 3 in Recirculation position.
3) Place VALVE 2 in position to let clean water circulate thru Injection Pump from flush pump.
VENT PRODUCT TANK. Start the Flush System, pump approximately 1/2 gallon into Injection
Tank.
4) Reposition VALVE 2 and VALVE 3 to allow rinse mixture to be injected. Spray rinse mixture at
normal recommended rate.
5) Repeat this procedure until Pump and Tank are clean. (i.e. Triple rinse).
