QUOTE(adamgombak @ Aug 28 2020, 10:33 PM) can show picture of flexible hose? Just google expansion joint or flexible joint for pump and you can see the picture. All industrial pumps are installed with this kind of joint to reduce the fatigue from pump vibration.can stand pump pressure? how to specify when buying? how long must hose be from the pump to join to say pvc pipe to reduce vibration? use what sort of clips to join? gotta use adaptor at pump outlet & also at pvc pipe? hose easily available from usual hardware shop? I think it should be something that can be easily sourced since pump installation should be connected with flexible joints. This post has been edited by blanket84: Aug 29 2020, 12:17 AM |
