6.4.4
Chemical may be attacking packing elastomer material
The packing will appear swollen or badly
damaged once removed from the packing gland if it is being attacked by the chemical. Contact CheckPoint or your
authorized CheckPoint distributor. If the chemical has recently been changed or if the pump has just been placed
in service, there is a good chance that new packing materials are needed to do the job.
6.4.5
Chemical may be attacking plunger material
The plunger will be severely worn, pitted, or corroded when
inspected. A different plunger material, such as Hastelloy, 17-4 SS or ceramic is indicated.
6.4.6
Chemical may have abrasives suspended in it
The plunger will appear scored and the packing will appear
severely worn if trash in the chemical is indicated. To remove such particles prior to entering the pump, CheckPoint
offers the Series ST In-Line Chemical Filter available in a range of mesh sizes.
6.5 Other problems
If you are experiencing an operating problem not listed above, or if none of the above troubleshooting actions
solves your operating problem, please contact your authorized CheckPoint distributor, or call CheckPoint directly at
(800) 847-PUMP or (504) 340-0770, to determine appropriate next steps. Once CheckPoint has had the opportunity
to help you troubleshoot your problem, please keep in mind the following regarding repairs:
6.5.1
CheckPoint offers an exchange program to keep you in service
We will ship you a rebuilt pump, which
you will be able to install prior to sending us your existing pump. When we do receive your pump, we will tear it
down, rebuild it, and report back to you any problems we uncovered, charging you for only those repairs you
required. If you bought your pump from a distributor, please contact them directly to arrange for this service.
6.5.2
Nothing beats factory-direct repairs
Although the Series 1250 has been designed to be easy to operate
and to repair, the best way to ensure continued reliable service is to have your pump repaired at the factory. This is
the only way to ensure you always get the quality and reliability you invested in when you purchased the product.
6.5.3
Remember that after you repair your CheckPoint pump, it should perform as well as it did when it was
new
If it doesn’t, call us to determine what can be done to restore the pump to “like-new” performance.
6.5.4
Training sessions are available
Please call us to set one up.
