Ni-Hard IV or ceramic lining
So the wear is the problem. Have you tried changing the material of rubber lining to another material (Ni-Hard IV or ceramic lining) to reduce the wear effect. Or replacing the rubber lined spool by entirely Ni-Hard IV spool. That may be extending the replacement period substantially.In case you eliminate the spool, and connected flange does not meet the pump flange dimensions (PCD and bolt sizes) you had better get Warman's approval for what you are doing. Sketching your idea is going to cut a lot of discussion I guess.Additionally I suggest you look at the following link, may be helping you in the process:Very interesting coupling, I can think of many piping arrangements that would benefit from this. I did speak with a Warman rep. and he had no objections with bolting an 8" line to the 6" discharge flange however, I also seek the advice of this forum for more in depth discussions. Ni-Hard is truly the way to go! and I will follow up on both."high" pressure water pump
"high" pressure water pump
I feel silly asking this question, but I've searched high and low on the internet and can't find a pump solution for my needs. The requirement is 500 ft of head (including losses) at 6 gallons per minute flow rate. I have 240 volt service Vacuum pumps available. Most "deep well" pumps seem to tap out at 100 ft or so. The highest I've found is 300 ft. I do not need submersible.I am looking for a selection of pumps that service this range. Can anyone point me in the right direction?
