WARNINGS AND CAUTIONS

In this document you will find warnings and cautions for installation, use
and maintenance of the pumps.
WARNING:
This symbol aware that there is a danger of serious
bodily injury or death if you ignore the warning described.
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 BALCRANK.
• Fluids not suitable for the pump can cause damage to the pump unit and
involve risk of serious personal injury.
• Always consult BALCRANK 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
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.

Here's the meaning of symbols you may find in this document and general
warnings that you should keep in mind.
CAUTION:
This symbol aware that there is a danger of personal
injury or property damage if you ignore the caution described.
WARNING
consumption, there is a possibility of trace contamination of lead.
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.
