I'm looking to replace a few 6" pinch valves (one manual and one automated). The material being conveyed is nickel chips (approx. 17-25mm in diameter and approx. 3-5mm thick, density of 8.9g/cc @ 300K). The rubber internals are wearing out (gravity feed piping system @ 40 degrees off of a 80T...

I'm curious to know if anyone has had the opportunity to use a peristaltic pump and if it would be of benefit in this case. Watson Marlow/Bredel has an SPX50 pump that would surely eliminate a lot of the problems we are seeing now with heat being generated nor would we require cooling of the...
jet1749; The Flowserve CPX mag drive pump is one of the models I am looking at (ISO overhung). Curious to know about pump reliability, flow conditions and why you changed out to peripheral (what make?). Thanks.
When I refer to "front bearing", I mean closest to the impeller but inside the stator assembly. Yes, the design is an overhung impeller. The contact surface was with the front bearing housing and impeller (metal to metal). Sorry for the confusion. The bearings are carbon graphite so there is...
First off, thanks for your replies. Yes, we have had the vendors involved, Chempump. They inspected the system, piping, flow, pressure, head, etc. Everything seemed to check out. We've had the same pumps in service for over 20+ years without much of a maintenance issue. Up until '96 (at...
I'm in need of some assistance. We've been having trouble with our canned motor pumps for the past number of years.
Possible solutions at this point are mag-drive pumps, seal less pumps or displacement chambers. We've replaced the same canned pumps on another system with displacement...
