GENERAL NOTES

“PHOENIX” series pumps are air-operated, double-diaphragm positive-displacement pumps, designed and manufactured for
pumping fluids that are chemically compatible with the constructive materials of the pump. The characteristics of the fluid
(pressure, temperature, chemical reactivity, specific weight, viscosity, vapor pressure) and of the environment must be compatible
with the pump characteristics and are defined in the ordering phase. Fluimac is not responsible for the pumped liquid. The
customer must ensure that there is compatibility between the pumped liquids and pump materials.
“PHOENIX” series pumps are self-priming; at the start-up the pipes can be empty.
The declared dry negative suction is referred to intake of water at a temperature of 20°C/ 68°F. The priming time and the
diaphragm’s life depend on.
-           the suction circuit (total length and diameter)
-           specific weight of the pumped fluid
-           viscosity of the pumped fluid
-           negative suction: max 5.000 cps (at 18°C / 64,4°F)
-           below head suction: max 50.000 cps (at 18°C / 64,4°F) “PHOENIX” series pumps may be used dry
“PHOENIX” series pumps cannot be used to generate a vacuum
Make sure that the physical-chemical characteristics of the fluid have been correctly evaluated.
The maximum temperature referred to water in continuous operation depends on the version of the materials (indicated on the
nameplate) and on the environment in which the pump will be installed:
The ambient temperature interval is related to the choice of materials (specified on the identification plate):

The pump may be operated at a maximum pressure equal to 1.5 times the head value with closed delivery.
The value of the vapor pressure of the pumped fluid must be greater (of at least 3 mwc - meters of water column) than the
difference between the total absolute head value (pressure on suction level subtracted of the suction height) and the leakages of
the suction section. The pumped fluid may contain particles suspended in different concentrations in accordance with the type of
valve assembled:

OPERATING PRINCIPLE

The pneumatic distribution system sends compressed air behind one of the two diaphragms (A), which pushes the fluid
towards the delivery circuit. Simultaneously, the opposite diaphragm (B) is in the intake phase since it is dragged by the
shaft that connects it to the other diaphragm (A) under pressure; air present behind it is discharged into the environment
through the flow rate regulator present on the pump, while a pressure drop is created in the fluid chamber which sucks
the fluid from the suction circuit. When the diaphragm (A), under pressure, reaches the stroke limit, the distributor
switches the two inputs to the chamber on the diaphragms air side, putting diaphragm (B) under pressure and
diaphragm(A) in discharge. When the pump reaches its original starting point, each diaphragm has carried out one air
discharge stroke and one fluid delivery stroke. This sequence of movements makes up a complete pumping cycle.
