Mark Upton Posted: Jun 21, 2014 10:03 PM	stick pump issue Hello. On my last spray job, my A side barrel ran out, and the pump pounded off the bottom of the barrel until I was able to get up and shut it off. When placed in the new drum, the pump rapidly pumped and seemed like it wasn't getting it's prime back. I was unable to make it work on the job after that. Can you suggest a way to make this work properly? It has only sprayed approx 9 sets of foam in less than a year. Thx.

The inlet ball seat or ball itself can be damaged, get out of round and not seat properly, You can damage the piston, packings even the cylinder. Take the pump apart and check the way everything fits together. Replace the packings, seals and anything else that looks out of shape. then try it out again

You will need to remove the air motor and re-attach. If you need further assistance, let us know what pump you have and I will be happy to send you the proper manual and some guidance. George
