Flush Inlet Strainer Screen - Graco Reactor 2 E-30 Operation

Flush Inlet Inlet Strainer Strainer Screen
Flush Flush Inlet Strainer
The inlet strainers filter out particles that can
plug the pump inlet check valves. Inspect the
screens daily as part of the startup routine, and
clean as required.
Isocyanate can crystallize from moisture
contamination or from freezing. If the chemicals
used are clean and proper storage, transfer, and
operating procedures are followed, there should
be minimal contamination of the A-side screen.
Clean the A-side screen only during daily
startup. This minimizes moisture contamination
by immediately flushing out any isocyanate
residue at the start of dispensing operations.
1. Close the fluid inlet valve at the pump inlet
and shut off the appropriate feed pump.
This prevents material from being pumped
while cleaning the screen.
2. Place a container under the strainer base to
catch drain off when removing the strainer
plug (C).
3. Remove the screen (A) from the strainer
manifold. Thoroughly flush the screen with
compatible solvent and shake it dry. Inspect
the screen. No more than 25% of the mesh
should be restricted. If more than 25% of the
mesh is blocked, replace the screen. Inspect
the gasket (B) and replace as required.

4. Ensure the pipe plug (D) is screwed into the
strainer plug (C). Install the strainer plug
with the screen (A) and o-ring (B) in place
and tighten. Do not overtighten. Let the
gasket make the seal.
5. Open the fluid inlet valve, ensure that there
are no leaks, and wipe the equipment clean.
Proceed with operation.
