BEFORE CONNECTING 

EJECTOR TO AIR LINE

Airline  lubrication  is  necessary  for  the 

proper performance and life of this ejector 

Be  sure  that  the  proper  airline  filter. 

lubricator  and  regulator  can  supply  the 

volume  of  air  necessary  to  operate  the 

ejector at the speed required.

OPERATING PRECAUTIONS

Use Lincoln replacement parts to assure 

compatible pressure rating.

Heed ALL warnings.

ALWAYS check equipment for proper 

operation  before  each  use,  making 

sure safety devices are in place and 

operating properly. DO NOT alter or 

modify any part of the equipment  as 

this  may  cause  a  malfunction  and 

result in serious bodily injury.

DO NOT OPERATE Ejector in excess of 

recommended pressure range.

NOTE:  A 24” length of 1/2” I.D. hose 

must be used at the material inlet to 

prevent hydraulic lock which may 

occur if rigid piping is used.

ALWAYS read and follow the 

fluid and solvent manufacturer’s 

recommendations regarding the 

use of protective clothing and 

equipment.

To reduce the risk of serious bodily 

injury or property damage. NEVER 

exceed the maximum air or fluid 

working pressure of the lowest 

rated system component.

OPERATION

Model 85250 Ejector incorporates an inline 

double povver air cylinder which produces 

a 35:1 ratio during the dispense cycle. This 

is achieved through special porting through 

the upper piston rod which allows air to flow 

and pressurize the top sides of the pistons.

When the Ejector is pressurized to dispense 

material, air should also be vented from the 

bottom of the lower piston. The bottom of the 

upper piston is never pressurized because 

of a small hole in the upper cylinder wall 

which exposes it to ambient pressure. As 

the Ejector continues its dispense stroke, 

it’s travel is limited by the adjustment screw.

When  the  Ejector  is  retracted,  air  is 

vented from the tops of the two cylinders 

and  pressure  builds  under  the  lower 

piston. When the Ejector is fully retracted, 

pressurized  material  enters  the  material 

inlet  and  refills  the  void  of  the  pumping 

chamber just in front of the plunger.

The  Ejector  is  now  ready  for  another 

dispense stroke.

SERVICE AND

DISASSEMBLY PROCEDURE

Always disconnect air supply to 

Ejector and relieve pressure before 

checking, servicing, or repairing 

any part of Ejector.

TOOLS REOUIRED

1.7/16 Open End Wrench

3. 5/8” Open 

End Wrench

4.  3/4” Open End Wrench

5.  7/8” Open End Wrench

6.  1-1/2” Open End Wrench

7.  Pliers

Disassembly of

Air Components

1.  Remove the four Bolts and Lock-

  washers (Items 2 & 3).

2.  Lift the Top Plate and Gasket off 

  (Items 4 & 5) Gasket must be 

  replaced.

3.  Remove the top Air Cylinder

  (Item 6).

4.  Hold the top of the Plunger (ltem 21 

with a 1/2” wrench through the slot ted 

holes in the Cylinder (Item 16) while 

removing the top piston Bolt (Item 1).

5.  Remove the Spacer (Item 8).

6.  Remove the top Piston and 0-ring 

sub-assembly (Items 7, 9 & I 0).

7.  Hold the center Cylinder (Item 30)

while lifting off the center divider

Plate and 0-ring subassembly

(Items 11 & 12) and upper Piston

Rod (Item 13).

8.  Remove the upper piston rod from the 

center divider plate.

9.  Remove the center Cylinder (ltem 30) 

which will include the lower Piston 

and 0-ring sub-assembly (Items 7,9 & 

10).

10. Remove the lower Gasket (Item 5)

    for replacement.

11.  Remove the  lower divider Plate, 

    Piston Rod and Connector (Items 

    14,29 & 15). At this point the entire 

    air unit is disassembled and all 

    seals can be replaced if necessary.

Disassembly of

Wetted Components

1.  Remove the Packing Nut and Gasket 

(Items 17 & 18).

2.  Remove the Bottom Plate (Item 19).

3.  Remove the Packing Retainer and 

  U-cup (Items 28 & 20).

4.  Remove the Cap (Item 27).

5.  Remove the Lock Nut (Item 25).

6.  Remove  the  Nose Adapter, Adjusting 

Screw and 0-ring Sub-Assembly (Items 

23. 26 & 24).

7.  Turn the adjusting screw all the way in 

(clockwise direction) to access the 

  0-ring for replacement.

8.  Finally remove the Gasket (ltem 22).  At 

this point the wetted components should 

be completely disassembled.

REASSEMBLY

To  reassemble  the  Ejector  reverse  the 

Disassembly Procedure.

IMPORTANT: The small holes in the upper 

Piston Rod (Item 13) and the upper CyIinder 

(Item 6) must be positioned towards the 

Body  &  Plunger  assembly  (ttem  21)  for 

proper function of the Ejector.
