Additional information and recommendations.
2.2 Intended Use
Use
The EcoPump HP is an auto-suction pneumatic hori-
zontal piston pump.
The EcoPump HP may only be used for pumping
water-based and solvent-based flammable and non-
flammable coating materials and their detergents.
The pump is only intended for industrial use.
The pump may only be operated within the approved
technical data Ä 12 “Technical data”.
The pump is approved for use in explosive areas of
Ex zones 1 and 2.
Misuse
If used improperly, it can cause serious injuries.
Examples of wrong use are:
nUse outside a closed process or a remotely con-
trolled and automated process
nInstallation of the pump in an area without forced
ventilation
nUse of unapproved materials, see safety data
sheets
nMaking conversions or changes on your own
nUse of non-conductive fluids Ä 12.11 “Material
specification”
nUse in explosive areas Ex zone 0
nUse of components unapproved by Dürr Systems
Ex labeling

2.3 Residual risks
Danger of explosion due to sources of ignition in
an explosive atmosphere.
Sparks, open flames and hot surfaces can cause
explosions in explosive atmospheres. Serious injury
and death could be the consequence.
nBefore carrying out any work, make sure that there
is no explosive atmosphere.
nDo not use any sources of ignition and no open
light in the work area.
nDo not smoke.
nDo not unpack Pump in Ex zone.
nDispose of packaging according to regulation out-
side of Ex zone or store it.
nUse tools with Ex approval.
nGround Pump.
nWear suitable protective equipment.
Sparks due to electrostatic discharge
If the pump is not properly grounded or the potential
equalization fails, components may get charged elec-
trostatically. Electrostatic discharge can cause sparks
that in explosive atmosphere can cause a fire or an
explosion. Serious injury and death could be the con-
sequence.
nGround Pump as specified.
nCheck connection of grounding cable during oper-
ation.
nMeasure volume resistivity.
Escaping material
Material escaping under pressure can cause serious
injuries.
Before working on the product:
nDisconnect the system, in which the product is
installed, from compressed air and material supply.
nDepressurize the lines.
nSecure the system against being switched on
again.
Danger from harmful or irritant substances
Serious injuries or death can result if you come into
contact with dangerous fluids or steam.
nPump Check regularly for leakage. Observe local
regulations and maintenance schedule.
nEnsure that the forced ventilation is operational.
nFollow the safety data sheet.
nWear specified protective equipment.
2.4 Conduct in the event of a hazardous situa-
tion
Conduct in case of danger depends on the operator’s
installation situation.
Perform the following activities:
nClose lines.
nSecure against reconnection.
nDepressurize lines.
2.5 Staff qualification
WARNING!
Inadequate qualification
Wrong estimation of dangers can cause serious
injury or death.

3 Design and Function
3.1 Control Unit
Fig. 2: Control Unit operation
1 Motor
2 Sound muffler
3 Compressed air connection
4 Valve
5 Distributor block
Air reaches into the distributor block of the control unit
(5) via the compressed air connection (3). The valve
(4) in the distributor block (5) controls the air intake to
the motor (1). The air outlet is through the two sound
mufflers (2).
Design and Function
08/2020 EcoPump HP - MPU00020EN 7/56

3.2 Motor
Fig. 3: Motor operation
1 Cylinder
2 Piston
The pneumatically operated motor drives the pump.
The piston (2) of the pneumatic motor divides the cyl-
inder (1) into two air chambers. Compressed air
moves the piston (2) back and forth in the cylinder (1).
When the piston (2) reaches one end of the cylinder
(1), the piston switches the switch valve. The switch
valve causes the control unit to change the supply of
engine air from one side of the piston (2) to the other.
The piston (2) then moves in the opposite direction.
3.3 Fluid part
Fig. 4: Fluid part operation
1 Suction line
2 Pressure line
3 Non-return valve in the outlet cylinder
4 Non-return valve in the piston
5 Piston rod
The motor and the fluid parts are mutually linked
through the piston rod (5). The movement of the
piston rod causes suction of the material into a fluid
part through the suction line (1). At the same time,
material is pushed out through the pressure line (2) in
the second Fluid part. Non-return valves (3) and (4)
prevent material from flowing back.
4 Transport, scope of supply and
storage
4.1 Unpacking
DANGER!
Electrostatically charged plastic films and foils
in potentially explosive areas
The foil and the product can charge electrostatically
at the time of the unpacking. Electrostatic discharge
can cause sparks that in explosive atmosphere can
cause a fire or an explosion. Serious injury and
death could be the consequence.
nUnpack product outside Ex zones.
nDischarge the product.
nDispose packaging outside of the Ex zone in
accordance with the regulation or store properly
for a later return.
