WARNINGS AND CAUTIONS

In this document you will find warnings and cautions for installation, use and maintenance of the Direcflo pumps.
A continuación le indicamos el significado de los símbolos y mencionamos unas advertencias generales que usted debe tener en cuenta.
WARNING: This symbol aware that there is a danger of serious bodily injury or death if you ignore the warning described.
CAUTION: This symbol aware that there is a danger of personal injury or property damage if you ignore the caution described.
WARNING: ¡CAREFULLY READ THE INSTRUCTIONS AND WARNINGS BEFORE OPERATING THE EQUIPMENT!
• This equipment is for professional use only.
• Do not degrade the integrity of the equipment. Use only original
replacement components from Samoa Industrial, S.A.
• Fluids not suitable for the pump can cause damage to the pump unit and
involve risk of serious personal injury.
• Always consult Samoa Industrial, S.A. if you have any questions about the
compatibility within the fluids and the pump materials, including
elastomers.
• Install and use the pump according to all local and national regulations
and abide all health and safety laws or legislation.
• The pump can produce fluid pressures equal to the air supply pressure. Do
not exceed the maximum allowable pressure of 115 psi (8 bar) air supply.
The total hydraulic pressure (differential pressure + system) should never
exceed 115 psi (8 bar).
• Never use a pump that leaks, that is damaged, that is corroded or
otherwise it may lack the capacity to contain the fluid.
• Frequently check that the bolts on the diaphragm cover of the pump are
torqued correctly.
• Do not use a model with aluminium wetted surfaces to pump fluids for
human consumption, there is a possibility of trace contamination of lead.
DESCRIPTION
Air operated double diaphragm pumps are air-powered, reciprocating
positive displacement pumps with two pumping chambers. Two diaphragms,
centrally located in the chambers, separate the compressed air (dry side)
from the fluid being pumped (wet side). A shaft transmits the reciprocating
motion of one diaphragm to the other. A directional valve alternatively
distributes the air from one chamber to the other; thus a reciprocating
movement of the diaphragms is created. With each stroke, fluid is discharged
by one of the diaphragms whilst the opposite diaphragm sucks new fluid
into the expanding chamber. Check valves, two on the discharge side and
two on the suction side, control and direct the fluid flow.

• Danger of explosion if used 1,1,1-trichloroethane, methylene chloride or
other halogenated hydrocarbon solvents with aluminium wetted materials.
It could cause serious injury and property damage.
• Inside the pump, diaphragms separate the fluid that is being pumped
from the air supply. If a diaphragm breaks, the fluid can leak out of the air
exhaust and contaminate the environment.
• When handling hazardous fluids, always route the air exhaust into a
suitable container and locate it in a safe place.
• When the fluid source level is situated higher than the pump, (flooded
suction), the outlet tank must be at a higher level than the product to
prevent spills.
• For pumps handling hazardous fluids that are a danger to humans or to
the environment, install a suitable container surrounding the pump to
prevent any leaks or spills.
• Ensure that the operators of this equipment are trained on the operation
and limitations. Use safety equipment as safety goggles or other
equipment required.
