IPSJules Posted August 23 Share Posted August 23 We are getting ready to refurbish a PVC and 316 SS pump that has had cupric chloride concentrate run through it. It has been cleaned. However, there is green residue. We will be plastic welding, chipping and scrapping this pumps. What are the dangers? Is this safe to do? How should we advise our customer to clean the pump?

chenbeier Posted August 23 Share Posted August 23 Should be no problem to scrap the pumps. The green residue is also copper chloride. Cleaning with ammonia solutions possible. Link to comment Share on other sites More sharing options...

The other one scrapping would be to dump the pump, but then I dont need cleaning of it. Link to comment Share on other sites More sharing options...
