  • CUTWATER? | Eng-Tips
    The "cutwater" is located in the discharge casing of a centrifugal pump and it directs the product discharge from the impeller into the discharge volute Along with the impeller, the cutwater can suffer damage from cavitation
  • cutwater | Eng-Tips
    Hello Does anybody know where I can get an information about the shape of cutwater in the centrifugal pumps and its influence on vane-pass frequency? Thanks
  • Effects of worn cutwater throat in pump - Eng-Tips
    Hi everyone, I have been searching online for information about the effects of a worn cutwater throat in pumps but have not been too sucessful Can anyone help ? Thanks alot
  • Piping Resonance | Eng-Tips
    I have usually found it to be cheaper to modify the internals of a pump than to re-design the piping (modifying pump internals includes: better selected impeller, modified cutwater, modified rings, etc) This, of course, is only if operational requirements can support it Tmoose mentioned a VFD - that could be great for you in a number of ways
  • Unusual cavitation on impeller outer diameter tip | Eng-Tips
    At the very least vibration (acceleration above 200-Hz) or contact ultrasound could be measured on pump case near cutwater while changing flow rate to indicate changes in Cavitation correlated with pump performance
  • Effect of excessive back clearance on re-circulation in pump
    Does anyone have any specific knowledge about the effect on the H-Q curve of excessive clearance between the impeller and the back liner casing of a simple end-suction centrifugal pump? I presume that internal recirculation will increase and that power goes up without an aparrent increase in
  • High BPF (3x) at Velocity and ENV measurements | Eng-Tips
    Increasing cutwater clearance beyond 20% and decreasing pump rotational speed both tend to reduce the number of harmonics present and their signal to noise ratio above the broadband level If streaming inlet vortices are involved then the problem is upstream of the pump impeller
  • Centrifugal Pump into Empty Main | Eng-Tips
    The impellor is overhung How would the cutwater cause problems at low heads during start up main filling that it wouldnt have during normal operation? Also why would the turbine type pump (axial?) not have problems operating away from its BEP? Wouldnt it have vibration problems due to pressure variations and dynamic imbalnces?
