How to clean your pump and fittings
Periodically clean the injection fitting / check valve assembly, especially when
injecting fluids that calcify such as sodium hypochlorite.
These lime deposits and other build ups can clog the fitting, which will increase
the back pressure and interfere with the pump accuracy. Warning: Severe cases
can physically damage the injection fitting and the increase back pressure can
cause increased wear on the pump components; gears, bearings and pump
tubes.
Please follow these steps when cleaning your injection fitting / check valves.
1. Wash the pump, tubing and
fittings out with clean water.
To do this, place the "suction
tubing" and "discharge
tubing" (injection fitting too) in
a container full of clean water.
2. Let the pump run in the clean
water for a couple of minutes
to remove all traces of
chemical.
3. Remove the lime deposits
with undiluted vinegar.
To do this, place the "suction
tubing" and "discharge
tubing" in a container full of
undiluted vinegar. See image
to the right.
In severe cases the
entire Injection Fitting
will need to be
unassembled and
cleaned using
undiluted vinegar.
Lime deposits
usually begin to
build up at point
of injection.

Note:
All diagrams are strictly for guideline purposes only. Always consult
an expert before installing the Chem-Feed/FlexFlo pump on specialized
systems. The Chem-Feed/FlexFlo should be serviced by qualified
persons only.
Caution:
Always wear protective clothing, face shield, safety glasses
and gloves when working on or near your metering pump.
Additional precautions should be taken depending on the solution being
pumped. Refer to MSDS precautions from your solution supplier.

Optional Threaded Injection Fitting (check Valve) installation.
Install the Injection Fitting directly into
a tee fitting. The solution must inject
directly into the flow stream.
Use Teflon® thread sealing tape on the
pipe threads of the Injection Fitting.
This illustration shows the Injection
Fitting installed in a tee fitting using the
1/2" threads.
You can install the Injection Fitting directly into your pipe.
Drill the correct size hole and then tap the hole for 1/4" or ½"
NPT.
Use Teflon® thread sealing tape on the pipe threads of the
Injection Fitting.
This illustration shows the Injection Fitting installed directly
into pipe using the 1/4" threads.
The Injection Fitting is designed to
install directly into either 1/4" or 1/2"
female pipe threads (NPT).
You can trim the injection point (nose)
if needed. See image to the right.
The nose section is designed to inject
the chemical away from the wall of
your pipe.
We do offer another Injector Fitting for
smaller pipe sizes (such as 1/2" and
1/4"). This fitting does not have the
same length at the injection point
(nose). See images to the right.
