1.4 Pump operation
Ruby Air Operated Diaphragm Pumps are oscillating positive displacement pumps with two pump chambers arranged opposite each other.
Both of these are separated by a diaphragm each into an air and a fluid section.
Both diaphragms are linked by a piston rod, so that with every stroke product is displaced to the outside from the one pump chamber and
product is drawn into the opposite pump chamber.
1.5 Improper use
Particularly, it is
FORBIDDEN
to use Ruby 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 with air pressures, temperatures or product characteristics that do not comply with the pump's technical data .
WARNING: 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 manufacturer
cannot foresee and for which he cannot be held responsible.
WARNING: the user must consider the ratio between the pump’s maximum surface temperature indicated on the marking
and the minimum ignition temperature of the layers and clouds of powder as shown in the ΕΝ1227-1.
WARNING: Use of the pump that does not comply with the instructions indicated in the use and maintenance manual will
cancel the safety and explosion protection requirements. The risks associated with use of the pumps under the exact conditions
set forth in the use and maintenance manual have been analysed, whilst the analysis of the risks associated with the interface
with other system components must be carried out by the installer
The user is responsible for classifying the area of use whilst identification of the equipment category is the responsibility of the
manufacturer
2.0 Safety Rules
Dangerous or hazardous practices or practice not complying with the safety rules and with the recommendations contained herein, may
cause serious injuries, material damage and even explosions and /or death for which the manufacturer cannot be held responsible.
WARNING: these instructions are essential for the pumps' compliance to the requirements of the 2006/42/EC directive and
must therefore be available, known, understood and applied.
WARNING: the personnel in charge of installing, inspecting and servicing the pumps must have suitable technical knowledge
and training in matters concerning potentially explosive atmospheres and the related risks
WARNING: use of the pumps in a manner that does not comply with the instructions indicated in the use and maintenance
manυaI will cancel all the requirements for safety and protection against of explosions.
WARNING: before intervening on the pump and/or servicing or repairing it, please- note that you must:
A - Discharge any product that was being pumped
B - Wash it internally using a suitable non-flammable fluid, then drain.
C - Cut-off the air supply using the relevant valve and make sure that no residual pressure remains inside it.
D - Close all on-off valves {delivery and intake sides) relative to the product.
Ε - Disconnect the network air supply;
F - Wear suitable individual protection before any maintenance or repair (goggles / face protection,
gloves, closed shoes, aprons and others).
WARNING: before using the pump, make sure that the fluid to be pumped is compatible with the explosion protection class
and with construction materials of the pump.
