1.2 LIST OF RESIDUAL RISKS
After a careful analysis and assessment of the hazards present during the operational phases affected by the
BOXER series Pneumatic Pumps, the necessary measures were taken to eliminate or reduce the associated risks
and the residual risks were reported and dealt with in the Installation, Use and Maintenance Manual (Original
Instructions) provided with the pump, so that they can be further reduced or eliminated through the design and inte-
gration of safety of the machines in which they will be installed:
HANDLING AND POSITIONING - CONSULT PROCEdURES IN THE ORIGINAL INSTRUCTIONS
• Impact and crushing hazard
INSTALLATION - CONSULT PROCEdURES IN THE ORIGINAL INSTRUCTIONS
• Hazards related to toxic and/or corrosive liquids to be pumped;
• Danger of chemical incompatibility with the uids to be pumped;
• Danger of produced leakage with dangerous uids; (provide ow and collection containment protections);
• Danger of chemical reaction with uids reacting to tap water for testing; (open and dry the internal parts of the
pump before installing it);
• Crushing hazard.
OPERATION - CONSULT PROCEdURES IN THE ORIGINAL INSTRUCTIONS
• Hazards related to toxic and/or corrosive liquids to be pumped;
• Danger of chemical incompatibility with the uids to be pumped;
• Danger of stress corrosion cracking (combined action of corrosion and/or incorrect application of a load) com-
bined with high temperatures;
• Fire hazard due to the deposit of ammable dust or use with temperatures higher than those shown on the prod-
uct Identication Plate.
CLEANING AND MAINTENANCE - CONSULT PROCEdURES IN THE ORIGINAL INSTRUCTIONS
• Hazards related to toxic and/or corrosive liquids to be pumped;
• Danger of projection of pump parts during disassembly, due to residual internal pressures (anomalous) in the pneu-
matic circuit of the pump;
• Danger of rupture of diaphragms in the absence of Scheduled Maintenance.
Those designing the machine/system in which the BOXER series Pneumatic Pump will be installed must consider
the residual risk indicated in each operational phase and must take the necessary safety integration measures
provided by the applicable directives, before commissioning. It is forbidden to commission the pump before the
Machine in which it will be incorporated has been declared compliant with Directive 2006/42/EC and any
further applicable specic Regulations and/or Directives.
Whoever works in these areas and deals with these operational phases must be a trained person and aware that
there may still be “residual risks” (related to the type of uid used and the chemical compatibility) that it was not
possible to eliminate.
Those in charge of these operations must always have at their disposal (consult and understand) all the informa-
tion contained in the Manufacturer’s Manual (Original Instructions or Translation of Original Instructions) and must
obtain the necessary Personal Protective Equipment (PPE) provided, before intervening.
The Customer, the Installation and Maintenance Technicians, the Qualied Operators are responsible for arranging
all the necessary measures so that access near the pump is reserved and limited to trained and qualied person-
nel and providing adequate information and reports of any residual risk on the machine/system in which it will be
installed, in compliance with current safety laws.
Since an endless variety of products and chemical compositions of the uids exists, the user is presumed to have the
best knowledge of their compatibility and chemical reaction with the pump’s construction materials. The purchaser
is strictly responsible for selecting the construction materials compatible with the uid(s) with which the
pump components come into contact.
The user can contact the Manufacturer or the Distributor for suggestions in relation to the construction materials
that offer the best chemical compatibility, however, neither the Manufacturer nor the Distributor will be held liable for
damage (malfunction, structural ageing, leakage or indirect damage) attributable to chemical incompatibility reac-
tions between the pump materials and the uids that come into contact with them.

2.5 DESCRIZIONE DELLA POMPA
2.5.1 PRINCIPIO DI FUNZIONAMENTO
Le pompe pneumatiche della serie BOXER sono costituite da uno Scambiatore Pneumatico con un ridotto
numero di componenti, che comanda tramite un perno centrale le membrane dei due gruppi pompanti. Le
membrane solidali al perno centrale di trascinamento vengono azionate con moto alternato in due stadi
(aspirazione-mandata) e costituiscono gli elementi pompanti.
Tra le due camere di pompaggio ed i condotti di aspirazione e mandata della pompa sono alloggiate le
rispettive valvole a sfera di ritenuta del uido.
Il principio di funzionamento a doppio stadio, avviene simultaneamente (mentre una camera è in fase di aspi-
razione, la seconda camera è in mandata) garantendo aspirazioni negative, prevalenze elevate e il pompag-
gio di uidi con alta viscosità e parti solide in sospensione (vedere 2.6 CARATTERISTICHE TECNICHE).
2.5.2 REQUISITI E CARATTERISTICHE DI INSTALLAZIONE
Le pompe pneumatiche della serie BOXER sono autoadescanti e possono funzionare a secco, e consen-
tono la variazione della velocità di funzionamento anche durante il servizio.
Possono essere impiegate per il ricircolo e il pompaggio di liquidi con elevata viscosità e parti solide in
sospensione (vedere 2.6 CARATTERISTICHE TECNICHE). I
l loro funzionamento è previsto per installa-
zioni in orizzontale, sopra e sotto battente, con prevalenze conformi alle caratteristiche di ciascun modello
(vedere 2.6 CARATTERISTICHE TECNICHE).
I condotti di aspirazione e di mandata devono essere opportunamente dimensionati (mai inferiori ai diametri
della pompa) per garantire le portate minime, le velocità ed un rendimento ottimale (vedere GRAFICO DI
RENDIMENTO). L’NPSH(r) richiesto dalla pompa (vedere Scheda Tecnica), deve sempre essere inferiore a
quello disponibile in aspirazione dal circuito del uido NPSH(a).
2.6 USO PREVISTO E USI IMPROPRI
2.6.1 USO PREVISTO
Le pompe pneumatiche della serie BOXER sono state progettate e costruite per il pompaggio di liquidi e
uidi aggressivi (acidi o alcalini) con composizione chimica e temperature compatibili con i materiali di com-
posizione della pompa, e viscosità apparente compresa tra 1 a 20.000 Cps a 20°C
(vedere Scheda Tecnica
Modello pompa); per viscosità superiori
a 20.000 Cps a 20°C intervengono fattori sici che richie-
dono una corretta valutazione pertanto
è sempre necessario contattare preventivamente l’Ufcio
Tecnico del Costruttore.
La massima temperatura ammessa per uidi di processo è comunque subordinata e/o declassata dal mate-
riale costruttivo della pompa e dell’impianto.
ATTENZIONE
I limiti massimi di temperatura si basano su due fattori, meccanici e corrosivi. Alcuni uidi impiegati,
potranno ridurre signicativamente le temperature massime di sicurezza a causa dell’elevato tenore cor-
rosivo.
Con il superamento della massima temperatura, non è più garantita la conformita della mar-
catura ATEX apposta sulla pompa.
2.6.2 CALCOLO DELLA MASSIMA TEMPERATURA DEL FLUIDO (per Zona 1 - Zona 21)
Qui di seguito viene indicata la formula per determinare la massima temperatura di processo del uido
consentita, per le pompe BOXER in versione CONDUCT (esecuzione: II 2/2 GD c IIB T135°C) per instal-
lazioni in
Zona 1 - Zona 21.

 ALLACCIAMENTO DEL CIRCUITO PRODOTTO
Dopo aver eseguito il posizionamento è possibile effettuare l’allacciamento della pompa al circuito del
prodotto operando come segue:
ATTENZIONE: pericolo di reazioni chimica all’acqua
Prima di effettuare l‘installazione della pompa per l’impiego con liquidi che reagiscono con l’acqua di rubinetto
è necessario effettuare l’apertura del circuito prodotto e provvedere all’asciugatura di tutte le superci interne.
Requisiti tubazioni impianto prodotto
• I raccordi di allacciamento devono essere dello stesso materiale della pompa con lettature cilindriche
(non impiegare lettature coniche);
• L’allacciamento alla pompa deve prevedere uno spezzone di tubo essibile con anima metallica
(è vietato l’allacciamento diretto alla pompa con tubo rigido);
• tutte le tubazioni essibili presenti, devono essere rinforzate con anima metallica;
• Le tubazioni devono essere auto sostenute e non gravare in nessun modo sulla pompa;
• Corretto dimensionamento dei condotti di (aspirazione e mandata) per una corretta velocità di aspirazione;
• NPSH(r) richiesto dalla pompa, inferiore a quello disponibile in aspirazione dal circuito del uido NPSH(a);
• Valvole di intercettazione prodotto (aspirazione e mandata, che non causino perdite di carico);
• Con particolato in sospensione, installare sull’aspirazione, una succhieruola, correttamente dimensionata
(supercie 2,5 / 3 volte la sezione di aspirazione della pompa con feritoia massima consentita);
• Con prodotti che cristallizzano prevedere circuito un di per lavaggio o strippaggio (con acidi compatibili);
• Condotti prodotto puliti e internamente e privi di residui solidi di lavorazione (trucioli, particolato, ecc.).
 Le pompe a membrana con aspirazione negativa sono inuenzate dai seguenti fattori:
- Viscosità del uido - peso specico del uido - diametro - lunghezza dell’aspirazione.
Posizionare la pompa il più vicino possibile al punto di prelievo (entro 2,5 m) e in tutti i casi mai superiore
a 5 m. l diametro del tubo di aspirazione non deve mai essere inferiore a quello dell’attacco della pompa;
deve essere opportunamente aumentato con l’aumentare della distanza o della viscosità del uido.
ATTENZIONE:pericolo di usura prematura e/o rottura membrane.
Il uido da pompare con aspirazione negativa non deve mai superare una viscosità di 5.000 Cps a 20°C
ed un peso specico di 1,4 Kg/l.
Con viscosità superiori
intervengono fattori sici che richiedono una corretta valutazione pertanto è
sempre necessario contattare preventivamente l’Ufcio Tecnico del Costruttore.
 Le pompe serie BOXER sono fornite con le sedi per attacco prodotto con lettature Gas cilindriche.
Per le connessioni ai collettori della pompa impiegare unicamente raccordi con lettature gas cilindrico
(non coniche) dello stesso materiale della pompa.
Esempio: (pompa in PP = raccordi in PP) oppure (pompa in INOX = raccordi in INOX).
Installare sul collettore di mandata e scarico una valvola manuale di uguale diametro all’attacco della
pompa (mai più piccola) o maggiorata per aspirazioni negative o per uidi con elevata viscosità.
Se necessario, caricare due giri di nastro in PTFE sul letto ed avvitare le valvole sui collettori
della pompa (con una forza di serraggio moderata) no a garantire la tenuta.

1.4 FOREWORD
BOXER pumps have been manufactured in accordance with Directives 2006/42/EC and 2014/34/EU in
compliance with the harmonised European standards EN ISO 80079-36:2016, EN ISO 80079-37:2016
and EN ISO 80079-38:2016.
With the drafting of this manual, the Manufacturer hopes that you can make the most of the performance
of the BOXER pumps, in complete safety; the BOXER pumps do not represent any risk to operators if
used in compliance with the Manufacturer’s Original Instructions.
The Customer, the Installation and Maintenance Technicians and the Qualied Operators are responsible
for arranging the necessary measures so that access near the pump is reserved to trained and qualied
personnel and providing adequate information and reports of any residual risk on the machine or system
in which it will be installed, in compliance with current safety laws.
All technical values refer to the “standard” BOXER pumps (see 2.7 TECHNICAL FEATURES) and we
remind you that due to a constant search for innovation and technological quality, the technical features
of the products could change without prior notice; it is necessary to always follow the version of the
Original Instructions provided with the pump.
It is forbidden to commission the pump, before the Machine in which it will be incorporated has been
declared compliant with the provisions of Machinery Directive 2006/42/EC, as well as with any further
other applicable Regulations and/or Directives.
Please note that the Original Instructions Manual, the Drawings and any other Technical Document deliv-
ered with the pump are condential and the property of the Manufacturer who reserves all rights (intel-
lectual property) and PROHIBITS the reproduction (even partial with any means) and the disclosure to third
parties without its written approval.

1.6 WARRANTY
The high quality of BOXER pumps is promptly conrmed to us by our Customers’ satisfaction. However,
should any defect appear, please contact the Manufacturer’s After-Sales Service, your Dealer or the
nearest Customer Service Centre where you will receive assistance as quickly as possible.
In any case, provide the following:
A. Identication of the pump through the Serial number on the label afxed to it;
B. Description of the detected anomaly.
All BOXER pumps are covered by the following warranty:
1 WARRANTY TERMS
The pump is warranted for 12 months (8 hours of daily operation) starting from the delivery date (see
Accompanying Document) on all mechanical parts found to be defective, except for the parts subject
to normal wear due to operation. The warranty provides for the free repair of the pump or the supply in
replacement of the defective parts, provided that the Manufacturer acknowledges the manufacturing defect.
The repair or replacement of defective parts constitutes full satisfaction of the warranty obligations.
2 INTERVENTION NOTIFICATION
The Purchaser must report any defect to the Manufacturer in writing within 8 days.
3 METHODS OF INTERVENTION
The warranty intervention will be exclusively carried out at the Manufacturer’s workshop after
shipment or sending of the defective pump at the Purchaser’s expense.
4 EVALUATION RESERVE
Warranty shall not be extended in case of repair or replacement.
5 EVALUATION RESERVE
The defective parts remain the Manufacturer’s property the moment they are replaced by the same under
warranty. If the parts are found not to be defective, the Manufacturer reserves the right to invoice the full cost
of the parts that have been replaced under warranty.
Purchaser responsibility
The Manufacturer will not bear the costs and risks for the shipping or transport of the defective and/or
repaired or replaced parts, including any custom charges. The warranty DOES NOT cover any indirect
damage and, in particular, any lack of production. In addition, the warranty does not cover any normal con-
sumable materials (diaphragms, balls and ball seats, etc.). The warranty does not cover parts damaged as
a consequence of incorrect installation, carelessness, neglect, incorrect maintenance, or damages due to
transportation or to any other reason or event that is not directly linked to functional or manufacturing defects.
Warranty and liability exclusion for chemical reactions:
Since an endless variety of products and chemical compositions of the uids exists, the user is presumed
to have the best knowledge of their compatibility and chemical reaction with the pump’s construction
materials. The purchaser is strictly responsible for selecting the construction materials compatible
with the uid(s) with which the pump components come into contact. The user can contact the Manu-
facturer or the Distributor for suggestions in relation to the construction materials that offer the best chemical
compatibility, however, neither the Manufacturer nor the Distributor will be held liable for damage (malfunc-
tion, structural ageing, leakage or indirect damage) attributable to reactions due to chemical incompatibility
between the pump materials and the uids that come into contact with them.
The warranty excludes all cases of tampering, improper use or incorrect applications or non-obser-
vance of the information contained in the Manufacturer’s Original instruction manual.
Any controversy falls within the jurisdiction of the Court of Busto Arsizio (VA) ITALY.

2.5 PUMP DESCRIPTION
 FUNCTIONING PRINCIPLES
BOXER air pumps consist of a Pneumatic Exchanger with a reduced number of components, which
controls the diaphragms of the two pumping units via a central pin. The diaphragms integral with the
central driving pin are operated with alternating motion in two stages (suction-delivery) and constitute the
pumping elements.
The respective ball valves are housed between the two pumping chambers and the pump delivery and
suction ducts.
The dual-stage functioning principle takes place simultaneously (while a chamber is sucking, the second
chamber is delivering), ensuring negative suctions, high heads and pumping of uids with high viscosity and
solid parts in suspension (see 2.7 TECHNICAL FEATURES).
 INSTALLATION REQUIREMENTS AND FEATURES
BOXER air pumps are self-priming and can run dry and allow varying the operating speed even during
service.
They can be used for the recirculation and pumping of liquids with high viscosity and solid parts in
suspension (see 2.7 TECHNICAL FEATURES). Their functioning is designed for horizontal installations,
above and below head.
The suction and delivery pipes can be suitably sized (never smaller than the pump) to ensure minimum ow
rates and optimal performance.
2.6 INTENDED USE AND IMPROPER USES
 PROPOSED USE
The air-driven BOXER pumps have been designed and constructed to pump liquids and aggressive liq-
uids (acid or alkaline) with chemical composition and temperatures compatible with the pump materials
and apparent viscosity of between 1 and 20.000 Cps at 20°C (see the Technical Data Sheet of the Pump
model); physical factors intervene for viscosities higher than 20.000 Cps at 20°C that require a cor-
rect evaluation, therefore, it is always necessary to contact the Manufacturer’s Technical Depart-
ment in advance.
The maximum temperature allowed for process uid depends on and/or is declassed by the construction
material of the pump and system.
CAUTION
The maximum temperature limits are based on two factors, mechanical and corrosive. Some of the u-
ids used may signicantly reduce the maximum safety temperatures due to the high corrosive content.
Conformity with the ATEX marking afxed on the pump is no longer ensured when the maximum
temperature is exceeded.
 CALCULATION OF THE MAXIMUM FLUID TEMPERATURE (for Zone 1 - Zone 21)
The formula used to determine the maximum allowed uid processing temperature for CONDUCT version
BOXER pumps is shown below, (execution: II 2/2 GD c IIB T135°C) for installations in Zone 1 - Zone 21.

 TEMPERATURE CLASSES FOR PUMPS TO BE INSTALLED IN AN EXPLOSIVE ENVIRONMENT
(Zone 1 and Zone M2):
The temperature class corresponding to the protection against the risk of explosion of the pumps designed
for use in Zone M2 with the presence of explosive atmospheres is T150°C.
The temperature class corresponding to the protection against the risk of explosion of the pumps designed
for use in Zone 1 with the presence of explosive atmospheres is T135°C (T4); all the data for calculating
the maximum uid temperature under the operating conditions are shown below.
NOTE
The equipment’s maximum temperature has been determined with no powder deposits on the external
and internal surfaces.
Denition of the Calculation Data (Zone 1):
T4 = ATEX temperature class 135°C;
Ta = maximum ambient temperature 40°C;
Tl = maximum temperature for dry use of the pump in the workplace (50°C);
Δs = safety factor (5°C);
Tx = calculation factor (Tl + Δs) only for Zone 1;
Tf = maximum allowed uid processing temperature.
CAUTION
In consideration of the admitted ambient temperature variation range in Zone 1 and Zone M2, uid service
temperature values higher than those indicated above will not permit compliance to the corresponding
temperature classes, respectively T4 (135°C) and (150°C), besides cause damages to the pump.
Where the user presumes that the temperature limits set forth on the product marking and in this
manual may be exceeded, a detection and protective device must be installed on the system to
prevent the maximum allowed temperature from being reached.
NOTE
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.
 IMPROPER USES
Any use of a BOXER pump other than that previously described and specied in Section 2.7 TECHNICAL
FEATURES, is to be considered improper and is therefore forbidden by DEBEM .
In particular, it is FORBIDDEN to use BOXER pumps for:
• production of vacuum;
• operation as an on-off valve, as a check valve (non return valve) or as a metering valve;
• pump operation for pumping powders of all types and kinds (ammable and non);
• operation with uids that are chemically incompatible with the materials of construction;
• operation with air pressures, process temperatures and/or functional characteristics that are incompatible
with the Technical Data of the pump and/or the Certication marking afxed;
• pump operation in potentially explosive environments that are not classied and/or compatible with
the type of execution of the pump (see Certication marking afxed and Declaration of Conformity).
• unsuitable pump use (incorrect choice of materials and installations) to operate in the presence of stress
corrosion cracking phenomena;
• operation with alimentary or pharmaceutical uids.
CAUTION
The risks associated with use of the pumps under the exact conditions set forth in the Manufacturer’s
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/user.
To correctly use and operate the BOXER FPC 100 pump, in accordance with the provisions of ATEX
Directive 2014/34/EU, the user is strictly prohibited from:
- detach the reinforcement anges, xed to pump casings and manifolds, from the PTFE surfaces;
- act on the nuts and bolts of the reinforcement anges, modifying their tightening.
Use of the pump that does not comply with the Manufacturer’s Original Instructions is prohibited
and invalidates the Warranty, the safety and explosion protection requirements.
