5.3 Measuring the Pump’s Output - Volumetric Test.
This volumetric test will take into account individual installation factors
such as line pressure, fluid viscosity, suction lift, etc. This test is the most
accurate for measuring the injector’s output in an individual installation.
1. Be sure the Injection Fitting and Footvalve/Strainer is clean and
working properly.
2. With the injector installed under normal operating conditions, place
the Footvalve/Strainer in a large graduated cylinder.
3. Fill the graduated cylinder with the solution to be injected and run the
injector until all air is removed from the suction line and the solution
enters the discharge tubing.
4. Refill the graduated cylinder, if necessary, and with the Footvalve
completely submerged in the solution, note the amount of solution in the
graduated cylinder.
5. Run the injector for a measured amount of time and note the amount
of fluid injected. A longer testing time will produce more accurate results.
6.0 How to Maintain the Pump
6.1 Routine Inspection and Maintenance
The Pump requires very little maintenance. However, the pump and all
accessories should be checked regularly. This is especially important
when pumping chemicals. Inspect all components for signs of leaking,
swelling, cracking, discoloration or corrosion. Replace worn or damaged
components immediately.
Cracking, crazing, discoloration and the like during the first week of
operation are signs of severe chemical attack. If this occurs, immediately
remove the chemical from the pump. Determine which parts are being
attacked and replace them with parts that have been manufactured using
more suitable materials. The manufacturer does not assume responsibil-
ity for damage to the pump that has been caused by chemical attack.
6.2 How to Clean the Pump
The Pump will require occasional cleaning, especially the Injection fitting, the
Footvalve/Strainer, and the pump head valves. The frequency will
depend on the type and severity of service
When changing the diaphragm, the pump head chamber and pump head
cover should be wiped free of any dirt and debris.
Periodically clean the injection/check valve assembly, especially when
injecting fluids that calcify such as sodium hypochlorite. These lime
deposits and other build ups can clog the fitting, increase the back
pressure and interfere with the check valve operation.
Periodically clean the suction strainer.
Periodically inspect the air vents located on the back of the motor
compartment and under the pump head. Clean if necessary.
CAUTION: PROPER EYE AND SKIN PROTECTION MUST BE WORN
WHEN INSTALLING AND SERVICING THE METERING PUMP
