START-UP
GENERAL DESCRIPTION
1. Turn pressure control knob until motor starts to cycle.
2. Allow pump tocycleslowlyuntilit isprimedandallair ispurgedfrom
the fluid hose or dispensing valve.
The1” metallicdiaphragm pumpoffershighvolumedeliveryeven atlow
airpressures,easyselfpriming,theabilitytopumpvariousviscosityma-
terials and the ability to pass solids (as stated in the chart above). The
pump is offered with optional wetted parts configurations to satisfy a va-
rietyofapplicationrequirements.Refertothe“ModelDescriptionChart”.
3. Turn off dispensing valve and allow pump to stall - check all fittings
for leakage.
4. Adjust the regulator as required to obtain desired operating pres-
sure and flow.

GENERAL SERVICE NOTES:
S Use flexible connections (such as hose) at the suction and dis-
charge, these connections should not be rigid piped and must be
compatible with the material being pumped.
S Clean and inspect each part thoroughly upon disassembly, look for
deep scratches on metallic surfaces and nicks, cuts or flat spots on
“O” rings. Replace any of the parts that are of questionable condi-
tion.
S Install a ground wire where applicable.

and metallic moving parts with Key-Lube grease upon reassembly.
S SERVICE NOTE: PTFE “O” rings are not resilient and they should
always be replaced with new ones.
1. Install the (164) back-up ring by pulling it apart, twist or walk it down
into the cavity bottom inside the (163) bushing.
2. Install the (165) quad ring on top of the spiral ring by folding it in half
allowing it to get past the bushing i.d. and into the cavity.
3. Install the second (164) back-up ring as in step 1. Locate it on top of
the quad ring. Lubricate and smooth out the set with your finger to
assure good alignment.
4. Placethe(9) washer onto the(14) bolt, with thechamfer againstthe
bolt head, place the (3) “O” ring onto the (14) bolt and insert these
three parts thru the (6) plate.
5. Place the (7) diaphragm onto this assembly, (see assembly note,
page 5).
6. Assemble the (150) “O” ring and (148) piston assembly to the (149)
adapter piston, securing with the (151) nut.
7. Lubricate the (152) cylinder wall and insert the piston assembly into
the cylinder and through the bushing / quad seal.

2. Place (113) “O” ring on the (115) spacer, insert the spacer with the
legs facing outward, be sure not to block the internal ports with the
spacerlegs.Repeatthisprocessthreetimesandmakecertaineach
set is pressed in well.
1. Remove the two (124) tie rods blocking the (136) plugs.
2. Using a 3/8” Allen wrench, remove both (136) plugs. Check the
(137) “O” rings and make certain they are intact and undamaged.
Fragments of “O” rings can cause the pump to malfunction.
3. Install the last (112) washer and a(114) “O” ring, placethe last(113)
“O” ring onthe(116) spacer andinstall. Installthe last(114) “O”ring.
4. Lubricate the (111) spool and install (this is the side opposite of the
air inlet). Note: The end with the hole in it faces outward.
5. Install a new (137) “O” ring on the (136) plug and thread it into the
(101 motor center body.
S Note: Align plug carefully and take care not to damage “O” rings.
6. Assemble the (110) “U” cup to the (109) piston and install it into the
air inlet side with the lips facing outward.
7. Install new (137) “O” ring on the (136) plug and install into the (101)
motor center body.
8. Assemble(124)tierods,securingwith(29)nuts.NOTE:Torque(29)

1. For best results, rebuild the Major Valve stack one piece at a time.
Start with the (112) washer and install it in the side opposite the air
inlet. Place the washer into the bore with the raised edge facingout-

TROUBLE SHOOTING
Product discharged from exhaust outlet.
S Check for diaphragm rupture.
S Check tightness of bolt (14).
S Do not use air line additives containing solvents.
S Do not spray pump off with solvents, wipe clean only.
S Check “O” rings on (111) spool in major valve.
S Check (103) sleeve and (2) “O” ring on (1) rod.
S Check (168) “O” rings on (167) pilot piston for wear.
Air bubbles in product discharge.
S Check connections of suction plumbing.
S Check “O” rings between intake manifold and fluid caps.
S Check tightness of bolt (14).
Low output volume.
S Check air supply.
S Check for plugged outlet hose.
Pump blows air out main exhaust when stalled on either stroke, a
typical cause of pump malfunction can be attributed to problems
with “O” rings.
S For the pump to prime itself, it must be mounted in the vertical posi-
tion so that the balls will check by gravity.
S Check for pump cavitation -- suction pipe should be 1” minimum or
larger if high viscosity fluids are being pumped. Suction hose must
be non-collapsible type, capable of pulling a high vacuum.
S Checkalljointsonintakemanifoldsandsuctionconnections. These
must be airtight.
S Check for sticking or improperly seating check valves.
S Ifpumpcyclesatahighrateorrunserratically, check(168)“O”rings
for wear.
S Segments of broken “O” rings can move around or lodge in areas of
the air motor valve section.
S Swollen “O” rings can cause valve parts to stick or seize. Solvents
can ruin the “O” rings.
S Do not use contaminated air supply.
S Donot use light weight oilin air supply, it willwash theKey-Lube
grease out of the air motor section.
