Packed pump

Many packed pumps have an installed discharge bypass line running from the discharge nozzle of the pump to the packing box. This line... [Pg.221]

Because of its excellent chemical resistance, ETFE is used in the chemical industry for valve components, packings, pump impellers, laboratory ware, and battery and instrument components and for oil well, down-hole cables 41 Examples of such applications are shown in Figures 4.17 and 4.18. [Pg.80]

The best design of a pump for a pressure up to 300 lb. is the outside center-packed pump, illustrated in Fig. 18. The plunger can be watched and any cutting readily detected from the outside. Leakage can be stopped while the pump is in operation. [Pg.124]

The column can be packed by various methods, but the most common method is to use a slurry of the stationary phase. Once the initial end frit has been manufactured, the capillary can then be attached to a packing reservoir, which contains a slurry of the stationary phase. The packing reservoir in turn is attached to a high-pressure packing pump that delivers the packing solvent. The packing material is... [Pg.2547]

Packed pump Centrifugal pumps that handle water or nonhazardous liquids do not use a mechanical seal. They use a cheaper and simpler packed seal. [Pg.21]

The 1889 text does not mention mechanical seals, as they did not exist then. These early centrifugal pumps were packed pumps. My old shift foreman, Henry Ziprean, showed me how to replace the packing for a sour water pump during the long strike in 1974 in Texas City. 1 have only done this twice, 39 years ago. But, since I did it with my own hands, I ve never forgotten the details. [Pg.490]

Yep. Packed pumps have their limits. Not any good when pumping stuff that don t lubricate—like propane and butane and such. [Pg.491]

Zip. If the seal faces run past each other and are pressed together by the bellows, I would think they would get real hot, just like if we overtightened the lantern ring follower on the packed pump. Why doesn t that also happen to the mechanical seal "... [Pg.491]

Three different piston-piston seal combinations are shown above. The left and right sets are for an analytical HPLC system the middle is from a column-packing pump. Note that the larger diameter of the center pump will allow for faster flow rates (displaces more volume per piston stroke). [Pg.149]
