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

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 2G Ex h IIB T4 Gb -- II 2D Ex h IIB T135 Gb
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
