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.
DANGER OF CORROSION, PRODUCT SPILLS AND/ OR EXPLOSIONS CAUSED BY CHEMICAL REACTIONS

9
For installation and use in a potentially explosive environment, comply with these general precautions
- ascertain that the pump is full and if possible, that the level is above it by 0.5 m;
- ascertain that the fluid treated does not contain or cannot contain large solids or solids of a dangerous shape
- ensure that the intake or delivery ports are not obstructed nor limited to avoid cavitation or pneumatic motor strain.
- also ascertain that the connection piping is strong enough and cannot be deformed by the pump weight or by the intake. Also check
hat the pump is not burdened by the weight of the piping
- If the pump is to stay in disuse for a long period of time, clean it carefully by running a non-flammable liquid detergent through it that
is compatible with the pump's construction materials
- if the pump was turned off for a long period of time, circulate clean water it in for some minutes to avoid incrustations.
- before starting, after long periods of disuse, clean the Internal and external surfaces with a damp cloth;
- check the grounding;
- always protect the pump against possible collisions caused by moving objects or by various blunt materials that may damage it or react
with its materials;
- protect the pump's surrounding ambient from splashes caused by accidental pump failure;
- if the diaphragms are completely torn, the fluid may enter the air circuit, damaging it, and be discharged from the exhaust port. It is
therefore necessary for the exhaust port to be conveyed by pipes to a safe area.
WARNING: the air supply pressure must never be over 7 bar or below 2 bar
WARNING: when using the pump with aggressive or toxic liquids or with liquids that may represent a health hazard you
must install suitable protection on the pump to contain, collect and signal any spills: DANGER OF POLLUTION, CONTAMINATION,
INJURIES AND/OR DEATH.
WARNING: the pump must not be used with fluids that arc not compatible with its construction materials or in a place
containing incompatible fluids.
WARNING: installing the pumps without on off valves on the intake and delivery sides to intercept the product in case of
spillage is forbidden: danger of uncontrolled product spillage
WARNING: installing the pumps without on-off. three way or check valves on the air supply piping to prevent the pumped
liquid from entering the pneumatic circuit if the diaphragms are broken is forbidden: danger of fluid entering the compressed air
circuit and being discharged into the environment
WARNING: Should the user think that the temperature limits set forth in this manual may be exceeded during service, a
protective device must be installed on the system to prevent the maximum allowed process temperature from being reached.
If exceeded, respect of the maximum temperature marked cannot be guaranteed
WARNING: The pumps must always be grounded irrespective of any organ to which they are connected. Lack of grounding
or incorrect grounding will cancel the requirements for safety and protection against the risk of explosion
WARNING: the use of pumps made with non-conductive material, which become charged with static, and without suitable
grounding for flammable liquids is forbidden: RIS OF EXPLOSIONS DUE TO STATIC CHARGE
WARNING: Aggressive, toxic or dangerous liquids may cause serious injuries or damage to health, therefore it is forbidden
to return a pump containing such products to the manufacturer or to a service center. You must empty the internal circuits from
the product first and wash and treat it.
WARNING: Pumps containing aluminium parts or components coming into contact with the product cannot be used to ρump
Ill-trichloroethane, methylene chloride or solvents based on other halogenated hydrocarbons:
DANGER OF AN EXPLOSION CAUSED BY A CHEMICAL REACTION
WARNING: Conductive Polypropylene, conductive PVDF pumps are not to be installed in applications where the pumps
may be subjected to oil, greases and hydraulic liquids

10
WARNING: The components of the pneumatic exchanger, including the shaft are made from materials that are not specifically
resistant to chemical products, if the diaphragm should break, replace these elements completely if they have come into contact
with the product
WARNING:The air-driven motor of the Ruby pumps is self-lubricating and will not require any greasing. Therefore a void
using Iubricated and non- dried air.
WARNING: ascertain that during service no anomalous noise appears. In that case, stop the pump immediately
WARNING: ascertain that the fluid at the delivery side does not contain gas. Otherwise stop the pump immediately
WARNING: Periodic controls must be made to ensure that there is no powder and/or deposits on the external and internal
surfaces of the pump and, if necessary, they must be cleaned with a damp cloth
WARNING: removal of the silencer and the air supply fitting must be done when free from powder. Before restarting the
pump, ensure that no powder has entered the pneumatic distributor.
To replace worn parts, use only original spare parts.
Failure to comply with the above may give rise to risks for the operator, the technicians, the persons, the pump and/or the
environment that cannot be ascribed to the manufacturer.
WARNING: diaphragm pumps with negative suction are affected by the following factors:
-viscosity and specific weight of the fluid;
-suction diameter and length.
Position the pump as close as possible to the point of collection {within 2.5 m.) and in any case never more than 5 m. The diameter
of the intake pipe must never be smaller than the connection of the pump, but must be increased as the distance increases. Fluid
to be pumped with negative suction must never exceed a viscosity of 5.000 cps at 20° C and a specific weight of 1.4 g/I. These
elements can cause derating and reduce the duration of the diaphragm: DANGER OF PREMATURE BREA AGE.
2.1 Equipotential bonding / earthing
In principle, pumps and accessories must be earthed or provided with equipotential bonding if there
is the possibility of product specific electro-static charging and when used in potentially explosive
areas. Pumps and pulsation dampers with ATEX II 2 Ex h IIB T4 b -- II 2D Ex h IIB T135 b
approval are therefore fitted with an earthing screw.
Please Pay attention
For Zone 1
• Aluminum in combination with stainless steel (greater or equal 16,5% Cr) is only be used if
the steel cannot corrode and no iron oxide and/or rusty particles can be deposited on the
