It is sometimes necessary to coat the underside of the baseplate with an epoxy primer. This may have been purchased as an option. Remove the rust preventative solution from the machined pads with an appropriate solution. 3.2 Site / foundation A pump should be located near the supply of liquid and have adequate space for operation, mainte- nance, and inspection.

  • Page 21: Piping

    3.6 Piping 3.6 Piping 3.6.1 General Guidelines for piping are given in the "Hydraulic Institute Standards" available from: Hydraulic Institute, 9 Sylvan Way, Parsippany, NJ 07054-3802 and must be reviewed prior to pump installation. WARNING: Never draw piping into place by forcing at the flanged connections of the pump. This may im- pose dangerous strains on the unit and cause misalignment between pump and driver.

  • Page 22: Suction Piping

    3.6 Piping Figure 13: Incorrect Do not connect piping to pump until grout has hardened and pump and driver hold- down bolts have been tightened. It is suggested that expansion loops or joints, if used, be properly installed in suction and/or discharge lines when handling liquids at elevated temperatures, so linear expan- sion of piping will not draw pump out of alignment (Fig.
  • Page 23 3.6 Piping Figure 14: Correct Figure 15: Incorrect Use suction pipe one or two sizes larger than the pump suction, with a reducer at the suction flange. Suction piping should never be of smaller diameter than the pump suction. Reducers should be eccentric at the pump suction flange with sloping side down and horizontal side at the top (Fig.
  • Page 24 3.6 Piping Figure 16: CAUTION: Pump must never be throttled on suction side. Suction strainers, when used, must have a net ''free area" of at least three times the suction pipe area. Separate suction lines are recommended when more than one pump is operating from the same source of supply.

  • Page 25: Discharge Piping

    3.6 Piping Figure 18: Suction Lift Conditions Suction pipe must be free from air pockets. Suction piping must slope upwards to pump. All joints must be air tight. A means of priming the pump must be provided, such as a foot valve, except for the 3796 self priming pump.

  • Page 26: Final Piping Check

    3.7 Final piping check Cushioning devices should be used to protect the pump from surges and water hammer if quick- closing valves are installed in system. 3.7 Final piping check After connecting the piping to pump: Rotate shaft several times by hand to be sure that there is no binding and all parts are free. Check alignment, per the alignment procedure outlined previously to determine absence of pipe strain.

The flushing liquid must be at a pressure of 5-15 psi (0.35-01 kg/cm2 ) greater than the seal chamber pressure. Injection rate should be ½-2 GPM (2-8 LPM). Other methods may be used which make use of multiple gland connections and/or seal chamber connections.

    4.2 Checking rotation Figure 21: Install the gland halves and evenly hand tighten the nuts. Connection of Sealing Liquid: If the stuffing box pressure is above atmospheric pressure and the pumpage is clean, normal gland leak- age of 40-60 drops per minute is usually sufficient to lubricate and cool the packing and sealing liquid is not required.
  • Page 31 4.2 Checking rotation Figure 22: Open air vents on the suction and discharge piping until water flows out. Close the vent valves. Suction Supply Below Pump (Except 3796) A foot valve and outside source of liquid may be used to prime the pump. Outside source of liquid can come from a priming pump, pressurized discharge line, or other outside supply (Fig.
  • Page 32 4.2 Checking rotation Figure 24: Figure 25: NOTICE: Model 3796 is a self-priming pump and does not require the use of a foot valve in the suction line. Refer to the pump's performance curve to determine the time required for priming. Close discharge valve and open air vents in casing.

  • Page 33: Other Methods Of Priming

    4.3 Starting pump Open valve in outside supply line until only liquid escapes from vent valves. Close the vent valves and then the outside supply line. Suction Supply Below Pump - 3796 NOTICE: The 3796 is a self priming pump and does not require manual priming prior to start-up (except for the initial charge).

    4.4 Operation CAUTION: Observe pump for vibration levels, bearing temperature and excessive noise. If normal levels are exceeded, shut down and resolve. 4.4 Operation 4.4.1 General considerations Always vary capacity with regulating valve in the dis charge line. Never throttle flow from the suction side.

    5.8 Impeller clearance setting The life of a mechanical seal depends on various factors such as cleanliness of the liquid handled and its lubricating properties. Due to the diversity of operating conditions it is, however, not possible to give definite indications as to its life. WARNING: Never operate the pump without liquid supplied to mechanical seal.

  • Page 71: Appendix

    8 Appendix 8 Appendix 8.1 Labyrinth Seal Installation Instructions 8.1.1 Description of Operation The labyrinth oil seal serves two functions. The first being to exclude environmental contamination from the power-end. This is accomplished with a series of tight clearance fits between the stationary and rotor. Any water that manages to enter the seal is eliminated from the seal through a drain slot located at the six o'clock position when installed.
  • Page 72 8.2 Installation Procedures NOTICE: During start-up when the parts of the labyrinth oil seal establish a voluntary running clearance, a small amount of wear is experienced as the parts are in contact. This wear produces a car- bon filled PTFE residue, visible at the outside diameter of the seal and at the drain slot. This is the result of the two surfaces being smoothed, similar to burnishing.
