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 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 analyzed, 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
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.

8
▪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 8 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.

9
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: RISK 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 aluminum parts or components coming into contact with the
product cannot be used to pump.
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.
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.

10
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 Kg/I. These
elements can cause derating and reduce the duration of the diaphragm: DANGER OF
PREMATURE BREAKAGE.

11
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 2/2 G Ex h IIC T4 Gb –II 2/2 D Ex h IIC
T35 Db 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 surface.
(appropriate reference to the properties of the stainless steel shall be given in the technical
documentation and instruction for use.
▪For Pumps with diaphragm type TFM:
1.Not run empty with flammable fluid/gas.
2.Flush before
For Zone 2
1.Not run empty with flammable fluid / gas.
2.Flush before
WARNING: the use of pumps made with non-conductive material, which become charged
with static, and without suitable grounding for flammable liquids is forbidden:
RISK OF EXPLOSIONS DUE TO STATIC CHARGE

12
3.0 Installation
To be observed before installation
1.The installation must only be carried out by persons who have the necessary skills for this work.
2.Before installation align the pump correctly and fasten it without any tension. Pipelines must be
assembled in a way that the basic weight of the lines is not reasting on the pump.
3.In order to avoid damage to the pump new installations should generally be checked for any
debris (welding beads, pieces of wire, etc.) in tank and pipeline system.
4.Consider the arrangement of the pump with respect to suction and discharge heads.
5.The pump system must be designed according to the requirements of the application. Valves or
spools must be installed as close as possible to pressure port. This also applies for T-fittings with
valve for bypass control or pressure relief valves, pressure gauges, flow control valves and shut-off
valves.
6.Thoroughly examine the alignment of the pump with the pipelines, in order to avoid strain and
premature wear.
7.Check all pipelines for leaks. This applies in particular for the suction line, in order to avoid the
intake of air.
8.If the fluid to be pumped contains solid particles bigger than specified , a filter must be installed.
The filter must be of such a size, that the change in resistance at the pump inlet port is only minor.
This filter must be permanently monitored and, if necessary, cleaned.
9.Fluids which change their viscosity must be permanently agitated, or the tank must be fitted with
a temperature sensor. With increasing viscosity start the agitator and/or the heating. This is of
special importance for intermittent operation!
Note: It is recommended to install flexible, shape and pressure resistant hoses or compensators
at the suction and pressure ports of the pump. This will prevent the transfer of pulsation shocks
into the pump.

13
3.1 Connection of air supply line
We recommend to supply the air through a hose to the pump. Using moisturized compressed air
requires the installation of a service unit with water separator. This control equipment can
additionally be used to regulate the flow capacity of the pump. The diaphragm must not be
subjected to shock loads. For this reason we recommend the installation of a spool, diaphragm or
needle valve as shut-off element.
WARNING: pneumatic supply to the Ruby pumps must he made using FILTERED. DRIED. NON
LUBRICATED OIL FREE AIR at a pressure of not less than 2 bars and not more than 8 bars.
WARNING: do not remove RESET for any reason and/or do not connect the air supply to the
RESET channel Warning! Do not use a ball valve as shut-off element.
Note: Especially for plastic pumps or pumps with PTFE diaphragms it is highly recommended to
install a slow start valve in the supply line to the pump. This valve protects both the diaphragm
and housing parts against suddenly occurring pressure shocks .

14
3.2 Connection of suction and pressure lines
Suction and pressure lines must be installed in a way that no additionally loads are applied to the
pump ports.
The tightening torque of the mounting screws and the pressure strength of the sockets and flanges
must be observed with the installation of the suction and pressure lines. After assembly check the
system for leaks.
3.3 Pump in suction operation
Ruby Air Operated Diaphragm Pumps are dry self-priming. Depending on the pump design a
suction head of max. 9 mwc can be reached, when the suction line is filled.
3.4 Pump in submerged operation
The Ruby Air Operated Diaphragm Pumps are suitable for submerged operation. However, it must
be assured that the surrounding fluid will not attack the pump.
When installing the pump make sure that the air discharge muffler has been removed and the
exhaust air is discharged from the fluid through a hose.
3.5 Connecting to the product circuit
After positioning the pump you can now connect it to the product circuit as follows:
WARNING: only fittings with cylindrical gas threads in materials compatible with both the
fluid to be pumped and the pump’s construction materials must be used.
For example:
Pump made from PP - PP fitting.
Stainless steel pump = stainless steel fitting.
CAUTION: Risk of breakage and/or yielding of the threads.
Do not use thread lockers and / or Teflon paste and conical threads. Excess PTFE tape and/or
excessive clamping pressure can cause cracks on the manifolds and/or yielding of the threads.
1.On the suction and discharge manifold install a manual valve of the same diameter as the pump
inlet (never smaller) to intercept the fluid correctly in case of spills and / or when servicing the
pump.
2.Install the sleeves to secure the flexible hoses on both valves.

15
WARNING: the pump must be connected with FLEXIBLE HOSES REINFORCED WITH A RIGID
SPIRAL of a diameter never smaller than the pump's connection. The filters or other equipment
installed at the intake side must be suitably dimensioned in οrder to avoid pressure drops. For
negative installations and/or viscous fluids, use hoses with an OVERSIZE DIAMETER, especially
on the intake side. Connections using rigid pipes may cause strong vibrations and break the
manifolds.
3.Connect the product intake and delivery hoses to their respective fittings whilst taking into
consideration the signs on the pump:
IΝ" = INTAKE (down) and
OUT" = DELIVERY (up)
or according to that indicated by the arrows.
4.Secure the hoses using the relevant clamps
WARNING: Provide appropriate support for the piping. THE PIPING MUST BE STRONG
ENOUGH TO AVOID DEFORMATION DURING THE SUCTION PHASE AND MUST NEVER WEIGH
DOWN ON THE PUMP IN ANY WAY OR VICE VERSA.
5.If used for drum suction (not below head), the submersed end of the intake hose must be
provided with a diagonally cut fixing to prevent it from adhering to the drum bottom.
WARNING: Ascertain that the fluid treated does not contain or cannot contain large solids or
solids of a dangerous shape and that the intake or delivery ports are not obstructed nor limited
to avoid either cavitation or pneumatic motor strain.
Connection off the product circuit finishes here.
3.6 Noise emissions (2003/10/EC)
In a room with several pumps you may experience an extreme development of noise . Depending
on the sound pressure level the following measures must therefore be applied:
Below 70 dB (A) : No special measures required
Above 70 dB (A) : Persons who are permanently in the room must wear ear defenders.
Above 85 dB (A : Room with dangerous noise level.! Each door must have a clearly noticeable
waning sign to warn persons from entering the room without ear defenders.
