    PIPING Guidelines for piping are given in the Centrifugal Pump section of the “Hydraulic Institute Standards” and should be reviewed prior to pump installation. WARNING Never draw piping into place by forcing at the flanged connections of the pump. This will impose dangerous strains on the unit and cause misalignment between pump and driver.
  • Page 24 CORRECT CORRECT PIPING Fig. 26 Fig. 28 Suction Lift Conditions Suction pipe must be free from air pockets Suction piping must slope upwards to pump. Fig. 27 All joints must be air tight. A means of priming the pump must be provided, such as a foot valve, except for the self priming pump.
