When a centrifugal pump undergoes negative effects such as reduced rotor damping, stiffness and efficiency along with increase in cavitation and vibration in general; the pump do require more and more power to operate with increased NPSH ( Net positive suction head ). Both the seal chamber and the stuffing box have the primary function of protecting the pump against leakage at the point where the shaft passes out through the pump pressure casing. Remove all of the used pump packing rings and the lantern ring. The pump drive … between the stuffing box and the shaft, Packing or Mechanical Seal is used. Centrifugal pumps are one of the world's most commonly used devices. Centrifugal pump inspection should be done regularly. Certain component failures of a centrifugal pump, such as coupling, hydraulic, static joints, and bearings, will cause the whole system to fail, but approximately sixty-nine percent of all pump failures result from the sealing device malfunctioning. If your team takes the time to conduct regular and detailed analysis of used or failed packing, you can identify the root cause of premature packing failure and take definitive steps. Centrifugal pump is a piece of rotary equipment that converts kinetic energy into the pressure head of the liquid. Centrifugal pumps with an internal suction stage such as water-jet pumps or side-channel pumps are also classified as self-priming pumps. How often the packing in a centrifugal pump should be renewed depends on several facts-such as the type of pump, condition of the shaft sleeve, and hours in use. RE: Gland packing in Centrifugal Pumps TenPenny (Mechanical) 21 Mar 13 08:36 To further complicate the question, Goulds used to offer (and may still do) an option of a quench gland for standard packing, the gland itself had a single row of small cross section packing in it, to contain the quench liquid. The pump suction may be under a vacuum so that outward leakage is impossible or the fluid may be too hot to provide adequate cooling of the packing. When the pressure at the bottom of the chamber is below atmospheric, it prevents air leakage into the pump. Packing gland for centrifugal pumps .
