Catch Test - Raven SideKick Pro Installation & Operation Manual

CHAPTER 5

CATCH TEST

Prior to starting a chemical injection application, perform a catch test (if desired) to manually verify the pump
output before operation. This test ensures the desired catch volume, volume caught, and flow correction are
correct.
Before starting:
1. Ensure pump and injection plumbing are primed. Refer to the Prime the Injection Pump section on page 37.
2. Verify the catch test vessel is large enough to catch the desired volume.
3. Ensure the end of the hose going from the pump to the catch vessel has a check valve to prevent excess fluid
from exhausting when the pump has stopped pumping.
To perform a catch test:
1. Set the hand valve on the injection pump outlet port to pump the fluid to the catch vessel through the
recirculation line.

2. Verify the following conditions exist:
a. Injection pressure is less than 12 PSI [82.7 kPa].
b. Pump is off.
c. Vacuum pressure is less than 11.5" [29 cm] of mercury.
NOTE: The vacuum switch on the pump will engage and a flow alarm will display if the product cannot be
drawn into the pump (e.g. vacuum pressure at or above 11.5" [29 cm] of mercury]). Check screens,
chemical tank lids, hose diameter and any hand valves between the chemical tank and pump inlet.
Also, verify that the product is flowing freely. Cold temperatures and high viscosity products may
cause high vacuum pressures and cause the pump to not operate properly.
3. Disconnect the coupler from the top of the chemical tank and place the recirculation hose in the catch test
vessel.
