PRESSURE HAZARDS
Current legislation requires that an air relief shut off valve is mounted on the supply circuit of the
pump motor to let air off when closing the supply circuit. Without this precaution, the motor residual
air of the motor may let the pump beat and cause a serious injury.
Please ensure that, a material drain valve is mounted on the material circuit to drain it (after
shutting down air to the motor and the pressure relief) before any servicing on the equipment. These
valves must be closed for air and opened for product when processing.
HIGH PRESSURE INJECTION HAZARDS
When working with high pressure equipment, special care is required. Fluid leaks can occur. Then
there are injection risks in exposed parts of body that may cause severe injuries or amputations :
Medical care must be handled immediately if product is injected under the skin or in other
parts of the body (eyes, fingers).
Never point the spray gun at any one. Never try to stop the spray with your hands or fingers
nor with rags or similars.
Follow the shut down procedure and always depressurize air and fluid circuits before
carrying out any servicing on the gun (cleaning, checking, maintenance of the material or
cleaning of the gun nozzles).
For the guns equipped with a safety device, always lock the trigger when you do not start the
gun.
FIRE - EXPLOSION - SPARKS - STATIC ELECTRICITY HAZARDS
A poor earth connection, inadequate ventilation, sparks or static electricity can cause an explosion
or fire. to avoid these risks when using or servicing KREMLIN REXSON equipment, the following
safety procedures must be followed :
ensure a good earth connection and ground the parts to be handled i.e. solvents, materials,
components and equipment,
ensure adequate ventilation,
keep working area clean and free from waste solvents, chemicals, or solid waste i.e. rags,
paper and empty chemicals drums,
never use electrical switches / power if in an atmosphere of volatile solvent vapour,
stop working immediately in case of electrical arcs,
never store chemicals and solvents in the working area.
TOXIC PRODUCT HAZARDS
Toxic products or vapours can cause severe injury not only though contact with the body, but also if
the products are ingested or inhaled. It is imperative :
to know the material products and their risks,
notified or hazardous materials must be stored in accordance with the regulations,
the material must be stored in an appropriate container, never place materials in a container
where there is a risk o spillage or leakage,
a procedure must be applied for the safe disposal of waste material. It must comply with all
prevailing regulations and legislations of the country where the equipment is to be used,
protective clothing should always be worn in compliance with the material manufacturers'
recommendations,
depending on the application and chemical safety instructions, safety glasses, hearing
protective earplug, gloves, foot wear, protective masks and possible breathing equipment
should be worn to comply with the regulations
(Refer to chapter "Safety equipment of KREMLIN selection guide).

KREMLIN REXSON 5 Manual : 574.331.112
CAUTION!
It is forbidden using any solvent or with halogenated hydrocarbon base and also products with
these solvents facing aluminium or zinc. The non-compliance with the instructions may cause
explosion hazards causing serious or fatal injuries.
EQUIPMENT REQUIREMENTS
Guards (air motor cover, coupling shields, housings,…) have been designed for a 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.
PUMP
Before carrying out any work, it is imperative to get used with the compatibilities of motors with
pumps before coupling. The operator shall understand the equipment and the safety instructions.
These instructions are available in the manuals of the pumps.
F
A
The air motor is designed to be mounted with a pump. Never modify any components or couplings.
Where operating, please keep hands away from moving parts. Before starting up the equipment,
please read the PRESSURE RELIEF instructions. Please ensure that any relief or drain valves
fitted are in good working order.
HOSES
Keep hoses out of circulation areas, moving parts or hot surfaces,
Never expose product hoses to temperature higher than + 60°C / 140° F or lower than 0°C /
32° F,
Never pull or use the hoses to move the equipment,
Tighten all fittings as well as the hoses before operating the equipment,
Check the hoses regularly; change them if they are damaged,
Never exceed the maximum working pressure (MWP) indicated on the hose.
USED PRODUCTS
Considering the variety of products that may be used by the users and the impossibility to check off all
chemical data, of possible reactions of chemicals to each other and their long term evolution,
KREMLIN REXSON can not be considered as liable for :
the bad compatibility of wetted parts,
risks for staff and surroundings,
for worn or out of order parts, for wrong working of equipments or units, as well as for the
qualities of final product.
The user must know and prevent the possible risks as toxic vapours, fires or explosions due to used
products. He shall determine the risks of immediate reactions or pursuant to repeated exposures of the
staff.
KREMLIN REXSON shall not be liable for psychic injuries, direct or indirect material damages further to
the use of chemicals.

KREMLIN REXSON 6 Manual : 574.331.112
ENVIRONMENT
Label marking on the Volurex
proportioning system
This equipment consists of a label plate with the name of the manufacturer, the
equipment part number, the interesting informations to use correctly the equipment
(pressure, voltage…) and the above pictogram.
The equipment is designed with and consists of high quality materials and
components which can be re-used.
The 2002/96/EC European Directive covers all equipments with a crossed-out bin
pictogram. Please inform yourself about the collection systems for electric and
electronic equipments.
Please according to local rules and do not throw the old equipments with
household wastes. A correct disposal of the old equipment will help prevent
negative consequences for the environment and health.
03. DESCRIPTION
The VOLUREX system consists of a Volurex proportioning gun and a control bay. It is designed for dispensing
materials beads (silicone, adhesive, mastic…) for cold and hot extrusion.
The VOLUREX assembly is linked to a robot that ensures the displacement of the proportioning system (or of
the part). The robot sends a signal to the control bay, thus providing the flow rate required to dispense the
bead.
The flow rate as well as the dosing are programmable and electronically controlled thanks to the control bay.
Depending upon the external informations (robot, manipulator, proportioning system), the bay drives the
system. It controls some safety devices that protect the proportioning system and its environment.

KREMLIN REXSON 7 Manual : 574.331.112
04. OPERATING PRINCIPLE
The proportioning system consists of :
The dispensing system consists of 3 actuators :
- The motor (6) of the proportioning system gives a translation motion to the piston (4) via the ball screw (5)
- The electrovalve (1a) enables the material coming from the fluid inlet (2) to enter into the chamber.
- The electrovalve (1b) enables the material from the chamber (3) to be extruded via the fluid outlet (7).
OPERATING
First position :
-The piston (4) is downwards and the ball screw (5) upwards.
Filling :
- The filling electrovalve (1a) opens to let the material enter in via the fluid inlet (2).
-The fluid enters in the chamber (3) via the shutting group (not represented).
- The piston (4) goes up because of the fluid pressure until coming into contact with the ball screw (5).

KREMLIN REXSON 8 Manual : 574.331.112
Pressurization :
- Thanks to the pressure sensor (8), the piston (4) goes down to put the fluid to the required pressure.
Extrusion :
- The extrusion electrovalve (1b) opens to let the material enter in via the fluid outlet (7).
- The piston (4) goes down in the chamber (3) with a speed that fits in with the output selected by the robot.
- The volume applicated is calculated thanks to the stroke carried out by the piston (4).
Drain :
The drain consists in :
- carry out an extrusion (empty the gun chamber) during a long duration shutdown of the proportioning
system or during a request of the operator.
- then carry out a filling operation (fill the gun chamber with material).

PNEUMATIC CONNECTIONS
Install a HP fluid hose between the mastic regulator fluid outlet and the VOLUREX proportioning system
inlet valve. The hose can be a heated one to make easier the fluid flow.
Install an air hose (4x6) to supply with compressed air the proportioning system. Connect it to the
compressed air network by means of a regulator.
ELECTRIC CONNECTIONS
