Air Operated Diaphragm Pumps
Warning!
Highly oil containing control air
causes soiling of the control
valve and swelling of the
O-rings.
1.4.4 Particle sizes, suction heads
In order to ensure correct functioning of the
pump the maximum product particle siz-
es listed in the following table must not be
exceeded.
1.4
Technical data
1.4.1 Dimensions, weights and
temperatures
See corresponding data sheet.
Danger!
For correct selection of the lift-
ing gear you should multiply the
specified weight with factor 1.5.
See table in 9.1.
.
In case of short-term exceeding the max.
permanent operating temperature you
should consult the manufacturer. When
using PP control blocks the max. ambient
temperature is 60° C.
When the pump is operated at higher tem-
peratures, diaphragm service life is likely to
be reduced.
Warning! For operation with
auxiliary heating you should
observe the temperature limit.
1.4.2 Control air
Max operating pressure see table 2.
DEPA Air Operated Diaphragm Pumps
are not subject to the pressure
equipment directive acc. to article 1,
para. 3.10, pressure equipment directive.
1.4.3 Air quality
Only air or inert gases of class 5 acc. to
DIN ISO 8573-1 may be used as control air.
(Class 5 corresponds with a max. particle
size of 40µm; max. particle density 10mg/
m
3
; max. pressure dew point +7°C; max. oil
concentration 25 mg/m
3
).
Operating the pump with dry, non-lubricated
and solids free compressed air prolongs the
lifetime of the air control unit.
*Values are reduced when using PTFE diaphragms,
seats and balls.
