PUMP DESCRIPTION

Proposed use
The air-driven Piusi MA and Piusi MP pumps have been designed
and constructed to pump liquids with an apparent viscosity of
between 1 and 50.000 cps at 20°C that are chemically compat-
ible with the pump's components. Fluid service temperatures
must range from +3°C to a maximum of 65/95°C according to
the material of the components. Its use is defined by the type
of material used to build the pump, the temperature class and
the type of fluid. The maximum temperature allowed for process
fluid or powder depends on and/or is declassed by the material
of the pump; if exceeded, respect of the maximum temperature
shown on the marking cannot be guaranteed.
TEMPERATURE CLASSES FOR PUMPS TO BE INSTALLED IN AN
EXPLOSIVE ENVIRONMENT
DEFINITION OF THE CALCULATION DATA:
T4 = ATEX temperature class 135°C
Ta = maximum ambient temperature 40°C;
Tl = maximum temperature for dry use of the pump in the work-
place (50°C);
Δs = safety factor (5°C);
Tf = maximum allowed fluid processing temperature
Functioning
The air introduced behind the diaphragm pushes the product
principles to the delivery side. At the same time, it uses the shaft to draw
the opposite diaphragm, which causes suction at the intake side.
When complete, the cycle reverses.
Improper use:
WARNING
In particular, it is FORBIDDEN to use Piusi MA and Piusi MP
pumps for :
- production of vacuum;
- operation as an on-off valve, as a non-return valve or as a
metering valve
- operation with liquid that is chemically incompatible, with the
materials of construction;
- operation with suspended products whose specific weight is
higher than the liquid's (for example with water and sand);
- with air pressures, temperatures or product characteristics that
do not comply with the pump's technical data;
WARNING
use of a Piusi MA and Piusi MP pumps for any other
use other than that previously described in the
chapter entitled "TECHNICAL CHARACTERISTICS"
is to be considered improper use of the pump and
is therefore forbidden by Piusi.
since an endless variety of products and chemical
compositions exist, the user is presumed to have the
best knowledge of their reaction and compatibility
with the pump's construction materials. Therefore,
before using the pump, all necessary checks and
tests must be performed with great care to avoid
even the slightest risk, an event that the manufac-
turer cannot foresee and for which he cannot be
held responsible.
