2.4 Safety systems
Several safety systems have been conceived during the diaphragm pump design and manufacture to
safeguard the operator, in compliance with pr EN 12621 Directive about paint.
SAFETY VALVE
A 8 bar calibrated safety valve is installed to ensure the pump working pressure does not exceed the
limits inside the feeding circuit.
If the calibration pressure is exceeded, the valve opens by releasing the excess of air.
WARNING
DO NOT REMOVE THE VALVE PLASTIC PROTECTION. ANY TAMPERING WITH COULD BE
DANGEROUS FOR THE OPERATOR AND COMPROMISE THE EQUIPMENT GOOD WORKING.
THREE-WAY VALVE
In case of anomalies during working, turn 90° the three-way valve lever. In this way the air supply will
be interrupted and the residual pressure inside the pump will be released.
17

18
Safety Some pictograms can be found on the pump with the safety warnings to follow by anyone who is
pictograms going to use it.
WARNING
THE MANUFACTURING COMPANY IS NOT TO BE HELD RESPONSIBLE FOR DAMAGE OR
ACCIDENTS TO PEOPLE OR THINGS COMING FROM THE NON-COMPLIANCE WITH THE
PRESCRIBED RULES.THE RESPONSIBILITY RESTS ENTIRELY WITH THE OPERATOR HIM
SELF.
2.5 Workable products
All DPS 90 diaphragm pumps are conceived to paint ferrous material in general, wood and plastic.
The products that can be delivered are: water-based and solvent-based paints with a maximum
viscosity of 85 sec/Ford # 4 (100 sec/NK-2).
To use the pump with special products ask for the manufacturer’s approval. Moreover, the pump
technical features will have to be adapted to the special product working.
The Company ANEST IWATA is not to be held responsible for any accident due to the pump use by
an UNAUTHORIZED and non qualified staff using it for purposes that are different from the above
mentioned ones.
WARNING
DO NOT USE:
- ANY HALOGENATED HYDROCARBON SOLVENTS, SUCH AS TRICHLOROETHANE, METHY-
LENE CHLORIDE OR SOMETHING LIKE THAT;
- ANY INFLAMMABLE OR VERY TOXIC PRODUCTS SUCH AS PETROL, KEROSENE, INFLAM-
MABLE SOLVENTS OR COMBUSTIBLE GASES;
- ANY HERBICIDE OR PESTICIDE
- ANY RADIOACTIVE FLUID

3.1 Operation description
Based on a simple manufacture, the operation consists in two diaphragm movement, which are both
fixed at the end of a rod, pressurizing and sending the paint.
The compressed air enters the air chamber from side A in picture 1. The diaphragm is moved to the
left, by pushing the paint.
At the same time, the diaphragm on the opposite end (side B) moves to the left by sucking the paint.
When the rod is completely on the left, the double pneumatic valve reverses the operations.
The compressed air enters the air chamber from side B in picture 2. The diaphragm is moved to the
right, by pushing the paint.
At the same time, the diaphragm on side A end sucks the paint.
The pump repeats the above-mentioned suction and delivery movements. The result is a steady and
pulsation-free material flow.
The main feature is the action of two pneumatic valves: the first one is a power valve feeding the
pump, and the other one a control valve always ensuring the movement.

4.1 Check on the purchased product
Before using the pump, make sure it has not been damaged during transport or storage.
Also check that all standard components are inside the packaging.
4.2 Conditions for installation
The equipment must be installed by a specialized and authorized staff.
In any case, follow the instructions below.
Painting must preferably take place inside a suitable spray booth equipped with suction devi-
ce.
Do not use the unit if the suction device is off.
WARNING
IF PAINTING IS CARRIED OUT OUTSIDE THE SPRAY BOOTH, ALWAYS OPERATE IN A PLACE
WITH A RIGHT VENTILATION TO AVOID CONCENTRATING INFLAMMABLE VAPOURS COMING
FROM SOLVENTS OR PAINTS.
4.3 Installation of DDP 90 D and DDP 90 CE WB base models:
- Place the pump on a stable support, to avoid movements during use.
- The distance between the pump and the fluid (height of suction) must be as short as possible.
However, it can vary according to viscosity and required delivery.
- Connect the air supply to the pump supply connection (see C on page 30).
- The suction pipe must have an inside diameter of at least 1/2” or slightly higher.
- To install the pump use two M8x12 screws by means of the special holes on the intake manifold.
Do not fasten the pump with any other system.
- Earth the free end of the ground cable directly.
WARNING
THE FLUIDS USED AND THE REQUIREMENTS MUST BE IN COMPLIANCE WITH SECTION 2.5
(WORKABLE PRODUCTS) AND WITH SECTION 5.0 (USE).
WARNING
- CONSULT THE LOCAL CODE FOR DETAILED INSTRUCTIONS RELATIVE TO GROUND CON-
NECTIONS IN THE WORK AREA AND TO THE TYPE OF SYSTEM USED.
- THE GROUND CABLE (INCLUDED IN THE SUPPLY) MUST HAVE A MINIMUM SECTION
EQUAL TO 1.5 mm
2
.
- ONE END OF THE CABLE MUST BE EARTHEN WHILE THE OTHER MUST BE CONNECTED
TO THE LATERAL LID OF THE DIAPHRAGM PUMP.
