    WARNINGUse of Baker equipment contrary to

    manufacturers specification may result inproperty damage, serious injury or fatality.

    8. Check body feed tank, fill when approximately3/4 down by opening body feed fill valve(14 AS) and closing discharge valve (8 PS) onpress skid.

    NOTE: Be sure that discharge valve (8 PS) is

    ALWAYSopen before closing either of the fill valves(14 or 15 on auxiliary skid).

    Bringing Centrifugal Pump On-Line1. Prime all lines (See Priming the Centrifugal

    Pump section).

    2. Open centrifugal intake valve (2 AS) one-fourth(1/4) of the way.

    3. Start pump at low idle.

    4. Stop M-15 pump (10 AS).

    5. Close M-15 discharge valve (11 AS).

    6. Run rpm up to 1,400 on centrifugal.

    7. Using centrifugal intake valve (2 AS), adjustpressure to same or little higher than it was withM-15, or until reaching desired rates.

    8. As rates slow down, gradually open centrifugalintake valve to increase rates.

    9. Once centrifugal intake valve is wide open andrates still need to be increased, raise rates bygiving centrifugal more rpm.

    10.Upon reaching 100 psi on press, or point thatrates are so slow that you no longer can keepup, proceed to break down.

    NOTE: Before breaking down, try to have enough

    clean fluid in active pit so rig will not have to stopwhile you clean the press. When working with smallsurface volumes, let rig know ahead of time so they

    can slow down (allowing you to get volume aheadand time to break down).

    Blowing (Breaking) Down1. Try to allow a half empty body-feed tank before

    breaking down.

    2. Turn centrifugal off and close intake valve(2 AS).

    3. Turn M-4 off (9 AS) and close body feed dis-charge valve (4 AS).

    4. Close main intake on auxiliary skid (3 AS).

    5. Open body feed fill valve (14 AS).

    6. Close discharge valve on press skid (8 PS).

    7. Open M-15 discharge valve (11 AS).

    8. Open through valve (8 AS).

    9. Start M-4 and M-15 pumps and continue pump-ing until there are no returns.

    10.Open by-pass valve (5 PS).

    11.Close main intake valve on press (4 PS).

    12.Close top and bottom return valve on press(9 and 10 PS).

    13.Jack hydraulic hand pump up to 4,200-5,000psi of pressure until locknut on cylinder can beunscrewed.

    14.Release hydraulic pressure on hand pump andturn closing screw back a few revolutions untilhydraulic cylinder can be swung clear.

    15.Place the locknut handle on the follow headand allow the hydraulic cylinder to rest on han-dle.

    16.Pull follow head back a little allowing any fluidstill on press to fall on drip pans and be pulledback into body feed tank.

    17.Once all fluid has been removed from press,turn M-4 and M-15 pump off. Remove drip pansand through hose. Begin to wash press plate byplate.

    18.Once clean, close press back and proceed to

    precoat steps.

    Priming The Centrifugal Pump

    Since this is not a self-priming pump, it will nor-mally require some type of external priming. Listedbelow are several methods which may be helpful.

    NOTE: * PS = Press skid sketch

    ** AS = Auxiliary skid sketch

    Priming by Backwash from Press1. Turn off centrifugal pump.

    2. Close centrifugal intake valve on skid (2 AS).3. Loosen wing-half on hose of centrifugal intake

    valve to allow air to escape.

    4. Once a steady flow of fluid starts coming out,tighten wing-half back up.

    NOTE: This works while precoating or filtering

    because part of the fluid going to the press at theTEE comes back through the pump.

    Priming with M-4 Air PumpWith Centrifugal Running

    1. Crack the centrifugal intake valve (2 AS) only asmall amount to allow very little fluid to pass

    through.2. M-15 should be turned off (10 AS).

    3. With centrifugal intake valve open (2 AS), startpumping from body-feed tank with M-4 at a fastpace and body feed discharge valve (4 AS) andcontrol valve (7 AS) opened all the way.

    4. Pump should regain prime shortly. At that time,slow M-4 down and get body feed back to nor-mal.

    With Centrifugal Stopped

    1. Turn off M-15.

    2. Close centrifugal intake valve (2 AS).

    3. Loosen centrifugal intake hose.

    4. Loosen centrifugal discharge hose betweencentrifugal and intake valve (2 AS).

    5. Open body feed discharge valve (4 AS).

    6. Open body feed control valve (7 AS).

    7. Start M-4.

    8. Shake intake on centrifugal until all air comesout.

    9. Shake discharge on centrifugal until all air es-

    capes.

    10.Tighten discharge on centrifugal.

    11.Shake intake one last time to make sure all aihas escaped.

    12.Tighten intake back down and shut off M-4

    pump, closing body feed discharge and controvalves.

    Troubleshooting

    Below are several reasons which have causedprime loss in the past:

    Through valve left open and fluid in trough hasall been pumped back into system, allowing airto enter into lines.

    Body feed tank has run dry, allowing air toenter.

    If precoating or circulating and unit leaks badlyaround plates, precoat tank may be allowingair to enter lines due to loss of fluid.

    Hose connections are not tight on suction linesomewhere, allowing air to enter.

    Return or settling pit has been drained dry andfluid level is below suction line.

    The pump is bad and air is entering some-where around worn seals or pump gaskets.
