KREMLIN REXSON - 1 - N° : 578.155.110-UK-1208
CAUTION :
Before any action on the pump, shut off the compressed air supply and
depressurize the system.
The pump is manufactured under the ATEX agreement and can not be modified.
KREMLIN REXSON will not be held responsible for any failure to comply with that instruction.
FLUID MOTOR OR AIR MOTOR REPLACEMENT (REFER TO DOC. 573.412.050 & 573.413.050)
Guards (air motor cover, coupling shields, housings …) have been designed for
safe use of the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or
damage to property due to removal or partial removal of the guards
Position the air motor piston in a high position before shutting off the compressed air and before
depressurizing the system.
Disassemble all the accessories of the pump (rods, filter).
Disassemble the pump from the cart, then from the bracket by removing the nuts that hold on the U-
bolts.
Put aside the pump (the pump is fitted with an hoisting ring).
Remove the 3 nuts (4) that hold on the 3 tie-rods (3).
Disassemble the air motor from the fluid section by removing the coupling rod from the air motor and
the piston from the air motor (hold on the coupling rod and unscrew the piston by means of a
wrench).
When changing the fluid section :
Position the spring protection on the new fluid section piston, assemble the air motor and the fluid
section, the tie-rods and the nuts.
Position the whole on the wall mounted unit.
When changing the air motor :
Remove the air supply from the old air motor and assemble it on the new one.
Assemble the new air motor and the fluid section (as it is specified previously).
Fix the pump on its bracket.

DISASSEMBLY / REASSEMBLY OF THE FLUID SECTION
Guards (air motor cover, coupling shields, housings …) have been designed for
safe use of the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or
damage to property due to removal or partial removal of the guards
SUCTION VALVE (15)
Disassembly
Unscrew the suction valve (16). (If the cylinder (2) remains
attached to the suction valve, unscrew both parts, then hold
cylinder (2) by inserting a rod into the cylinder holes designed for
this purpose).
The ball (17) is secured on the valve (16) by means of a circlips
(18).
Clean the parts with the appropriate cleaning solvent.
Reassembly
Reinstall the ball (17) and the circlips (18) on the valve body (16).
Change the seal (19). Lubricate it.
Lubricate the valve body threading.
Reinstall the valve assembly (15) on the cylinder (2).
CYLINDER (2)
In order to make easier the disassembly, a hole is made in the
cylinder (2) at each end.
Depending on the part that it is unscrewed first, insert a rod into
one of these holes to unscrew the other part.
When reassemblying, make sure the two seals (19 and 24) are
installed. Lubricate them.
Lubricate the inside of the cylinder (grease, type A1) and the threadings to prevent from
damaging the mobile packing (grease, type A2) (Refer to greases in the Assembly instructions §).
EXHAUST VALVE (6) AND MOBILE PACKING (7)
Disassembly
Unscrew the cylinder (2) and pull it downwards.
Unscrew the screw (6b).
Unscrew the exhaust valve (6a) with a flat wrench
n° 46 by holding the piston (3).
Remove the ball (8), the washer (6c) and the
mobile packing (GT seal - 7).
Clean the parts.
Reassembly
Install a new seal (7). Lubricate it.
Comply with the GT seal installation order.
Install the ball (8) on the exhaust valve (6a).
Lubricate the threading of the exhaust valve (grease, type A2).
Tighten the whole in the piston lower part (3).
Applicate glue (glue, type C2) (Refer to glues in the Assembly instructions §) on the screw (6b) and
lock it.

UPPER PACKING (9)
Disassembly
Disassemble the coupling rod from the air motor and
the piston (3) from the fluid section.
Unscrew the wetting-cup (4) by means of the wrench
provided with the pump.
Unscrew the cylinder (2) and pull the piston (3)
downwards. Pull the upper packing (9) upwards and
remove the seals (10 and 11).
Reassembly
Change the seals (10 & 11) and lubricate them.
On the support washer (12), install the seals (10 &
11) (comply with orientation and order) as well as
the the blocking washer (13) {upper packing (9)}.

Ind. 9
You must install a seal (11), then another one
(10) according to the opposite drawing.The first
seal in contact with the material must be the stiffer
one.
Grease the cone shapped tool (the tool is
supplied with the fluid section).
Position the upper packing (9) on the tool (32).
Slide the piston (3) into the flange (1) by inserting it
from bottom to top.
Position the tool equipped with the seals on the
upper part of the piston.
Slide the seals on the piston. The tool prevents from
damaging the seals when assemblying the piston.
Remove the tool.
Position the seals (always set up on the piston) into
the upper flange (1).

Hold the piston to prevent from its sliding downwards.
Tighten by hand the wetting-cup (4) without tightening the upper flange (1).
After reassemblying, fill up the pump with solvent and increase progressively the pressure to
maximum setting up of the seals.
After half an hour, stop the pump and open the exhaust valve to depressurize.
Retighten the wetting-cup (4) by means of the wrench supplied with the pump in order to be
in accordance with the drawing. Comply with assembly dimension.
Before reassemblying the different components :
-Clean the parts with the appropriate cleaning solvent.
-Install the new seals if it is necessary after having lubricated them with PTFE grease.
-Lubricate the piston and the inside of the cylinder to prevent from damaging the seals.
-Install new parts if it is necessary.

AIR MOTOR
AIR MOTOR REVERSING BLOCK
Guards (air motor cover, coupling shields, housings …) have been designed for
safe use of the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or
damage to property due to removal or partial removal of the guards
Disassemble the air motor cover (6) by removing the nut (4).
Dissociate the female yoke (27) from the reversing block lever (9).
Dismount the reversing-block by removing the screws (28).
Remount the new reversing-block in the reverse order of the
disassembly sequence.
CAUTION : the number of spirals must equally be
distributed on each fastening parts in order to get the above
dimension.
31.85 mm

DEGREES OF WEAR
The wetted parts in contact with the material are subject to wear with time. It depends, of course, on the
rates and duration of pump operating; also on the material handled.
Under normal operating and servicing conditions, with standard filled material not including foreign
matters or chemically aggressive, the average working life can be estimated as :
-1 million strokes for the tightness seals.
-10 millions strokes for the bellows.
