Definitions

  • This invention relates to pumps adapted to be tested in a water environment and subsequently maintained before actual use with minimized corrosion.
  • waterlines corrosion at such interfaces
  • the material is included in the form of a pellet and comprises a neutral blend of polycarboxylic compounds sold by Nuclear Technology Corporation, Route 85, Amston, Connecticut 06231 under the trademark NUTEK-876.
  • a wet motor pump 10 there is shown in. the figure in side elevation, partially broken away in vertical section, a wet motor pump 10 according to the invention. Construction of the pump is described in detail in my U.S. Patent No. 3,911,300, "Encapsulated Wet Dynamoelectric Machine Rotor", granted October 7, 1975, and hereby incorporated herein by reference.
  • pump 10 includes a - pumping chamber 12 which is formed in a pump chamber casing 14 with an inlet passageway 16 and an outlet passageway 18.
  • a pump motor 20 is connected to the pump casing 14.
  • the motor rotates drive shaft 30, which rotates impeller 32.
  • the pump motor housing 22 is removably attached to the pump chamber casing 14 and is sealed against leakage at the point of attachment by an O-ring seal 38.
  • the electrical controls for the pump motor 20 are contained atop the motor in a control housing 36 and are connected to a source of electricity.
  • zone 100 Between bearing 68 and seal 74 (numbering being as in the above incorporated-by-reference patent) is zone 100, and situated therein is pellet 102 of NUTEK-876. Typically 30 cc. of water will be left in pump 10 following testing, and preferably pellet 102 will be in 0.4 grams per 100 cc. of water to remain, or in this preferred embodiment 0.12 grams. The size and shape of pellet 102 should be such that it cannot escape zone 100, to cause possible interference with initial running of pump 10.
