4.3 SAFETY SYSTEMS
Several safety systems have been conceived during the diaphragm pump design and manu-
facture to safeguard the operator, in compliance with pr EN 12621 Directive about paint.
SAFETY VALVE
A 7 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 DISASSEMBLE THE SAFETY VALVE. ANY TAMPERING WITH COULD BE
DANGEROUS FOR THE OPERATOR AND COMPROMISE THE EQUIPMENT GOOD WORKING.
EXHAUST VALVE
In case of anomalies during working, turn 90° the exhaust valve lever. In this way the air sup-
ply will be interrupted and the residual pressure inside the pump will be released.
4.4 SAFETY PICTOGRAMS
Some pictograms can be found on the pump with the safety warnings to follow by anyone
who is 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.

wood and plastic.
The products that can be delivered are: solvent-based paints for all DPS-70C.TE models with
a maximum viscosity of 85 sec/Ford # 4 (100 sec/NK-2) and water based paint for all
DPS-70CN.TE models.
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
NEVER USE THE FOLLOWING HALOGENATED HYDROCARBON SOLVENTS :
- METHYL CHLORIDE, DICHLOROMETHANE, 1.2-DICHLOROETHANE, CARBON TETRA-
CHLORIDE, TRICHLOROETHYLENE,1.1.1-TRICHLOROETHANE WHICH CAN CAUSE
CRACKS OR DISSOLUTION ON GUN BODY (ALUMINUM) BY CHEMICAL REACTIONS.
- VERY TOXIC PRODUCTS SUCH AS PETROL, KEROSENE COMBUSTIBLE GASES;
- ANY HERBICIDE OR PESTICIDE
- ANY RADIOACTIVE FLUID
(Be sure that all fluids and solvents are compatible with gun parts.
We are ready to supply a material list used in the gun on request.)
Do not use with corrosive liquids (except for PH6-8)

5.1 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.
