Do not allow uids to freeze inside of pump.
When using inlet pressures higher than 10 psig (0.69 bar), the motor torque limit (VFD parameter 416) should be lowered to ensure the pump operates within the published operating map (see
Section 14). The rule of thumb is that the inlet pressure (psig) plus the motor torque limit setting (VFD parameter 416 in %) should equal 115 or less. The formula for this is therefore: [Motor Torque
Limit in %] = [115] – [Inlet Pressure in psig]. For example, an inlet pressure of 40 psig (2.76 bar) requires a motor torque limit of 75% (115 – 40 psig).
Values are determined according to noise test code ISO 20361 using ISO noise measurement standards. Measurement locations of 1m taken at pump/driver midline as per B.3.1 and 6.2 as dened
in standard. Calculated A-weighted sound pressure level using half-spherical surface. Published using uncertainty value of 3.
The 0° to -10° C derating of the VFD is due to the limitation in visibility of the liquid crystal display (LCD). The VFD is capable of operating in temperatures as low as -18° C if running in
"auto on" mode (serial or analog control) and not dependent on the keypad for pump running status or control.

READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE FLUID PRESSURE
STATIC SPARK
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING
STATIC SPARK. Can cause explosion re-
sulting in severe injury or death. Ground pump and
pumping system.
Sparks can ignite ammable material and vapors.
The pumping system and object being sprayed must
be grounded when it is pumping, ushing, recirculat-
ing or spraying flammable materials such as paints,
solvents, lacquers, etc. or used in a location where
surrounding atmosphere is conducive to spontaneous
combustion. Ground the dispensing valve or device,
containers, hoses and any object to which material is
being pumped.
Secure pump, connections and all contact points to
avoid vibration and generation of contact or static
spark.
Consult local building codes and electrical codes for
specic grounding requirements.
After grounding, periodically verify continuity of
electrical path to ground. Test with an ohmmeter from
each component (e.g., hoses, pump, clamps, contain-
er, spray gun, etc.) to ground to ensure continuity.
Ohmmeter should show 0.1 ohms or less.
Submerse the outlet hose end, dispensing valve or de-
vice in the material being dispensed if possible. (Avoid
free streaming of material being dispensed.)
Use hoses incorporating a static wire.
Use proper ventilation.
Keep inammables away from heat, open ames and
sparks.
Keep containers closed when not in use.
WARNING
Excessive fluid pressure developed by
pump can cause personal injury, pump damage or
property damage.
Fluid pressure developed by the pump do not exceed
the maximum as stated on the pump model plate.
Be sure material hoses and other components are
able to withstand fluid pressures developed by this
pump. Check all hoses for damage or wear. Be certain
dispensing device is clean and in proper working con-
dition.
WARNING
INSTALLATION OF ELECTRICAL COMPO-
NENTS FOR HAZARDOUS DUTY APPLICATIONS.
Pumps that will operate in environments defined as
“hazardous locations” must only be installed, con-
nected and set-up by qualied personnel with knowl-
edge and understanding of protection classes, regula-
tions and provisions for apparatus in hazardous areas,
for the region where the pump will operate, because
these regulations and provisions, along with the de-
nition of what constitutes hazardous areas vary by
location.
WARNING
ELECTRIC SHOCK HAZARD. This equip-
ment must be grounded. Improper grounding, setup,
or usage of the system can cause electric shock.
Turn o and remove power before disconnecting any
cables and before servicing or installing equipment.
Connect only to grounded power source.
All electrical wiring must be done by a qualied elec-
trician and comply with all local codes and regula-
tions. For North America hazardous locations (NEC/
CEC), ensure wiring is done by a qualified and certi-
ed electrician according to NFPA 70 and CSA C22.1.
Installation personnel should meet IEC 60079-14
Annex A for knowledge, skills and competencies of
responsible persons, operators, technicians and de-
signers.
The knowledge, skills and competences for mainte-
nance and inspection personnel must comply with IEC
60079-17.
The knowledge, skills and competences for repair and
overhaul personnel must comply with IEC 60079-19.
Refer to VFD label and manual for minimum capacitor
discharge time prior to any service.
WARNING
HAZARDOUS PRESSURE. Can result in
serious injury or property damage. Do not service or
clean pump, hoses or dispensing valve while the sys-
tem is pressurized.
Disconnect and lockout / tagout power supply to elec-
tric motor and VFD. Relieve pressure from the system
by opening dispensing valve or device and / or care-
fully and slowly loosening and removing outlet hose
or piping from pump.
WARNING
HAZARDOUS MATERIALS. Can cause se-
rious injury or property damage. Do not attempt to
return a pump to the factory or service center that
contains hazardous material. Safe handling practices
must comply with local and national laws and safety
code requirements.
Obtain Material Safety Data Sheets on all materials
from the supplier for proper handling instructions.
WARNING
EXPLOSION HAZARD. Models containing
aluminum wetted parts cannot be used with 1-1-1
-Trichloroethane,Methylene Chloride or other Halo-
genated Hydrocarbon solvents which may react and
explode.
Check pump crankcase section, PRV section, Oil mod-
ule section, uid caps, manifolds and all wetted parts
to assure compatibility before using with solvents of
this type.
WARNING
MISAPPLICATION HAZARD. Do not use
models containing aluminum wetted parts with food
products for human consumption. Plated parts can
contain trace amounts of lead.
CAUTION
Verify the chemical compatibility of the
pump wetted parts and the substance being pumped,
flushed or recirculated. Chemical compatibility may
change with temperature and concentration of the
chemical(s) within the substances being pumped,
flushed or circulated. For specific fluid compatibility,
consult the chemical manufacturer.
CAUTION
HOT SURFACE. Metallic wetted sections
can reach up to the same temperature as the fluid
temperature (up to 100°C). Precautions should be
taken to restrict access to hot surfaces when needed.
Proper personal protective equipment (PPE) for hot
surfaces should be worn. Check to ensure parts have
cooled down suciently prior to any maintenance.

EP20-XXXXX-XXX-XXX (en) Page 9 of 44
CAUTION
Maximum temperatures are based on
mechanical stress only. Certain chemicals will signi-
cantly reduce maximum safe operating temperature.
Consult the chemical manufacturer for chemical com-
patibility and temperature limits. Refer to PUMP DATA
on page 3 of this manual.
CAUTION
Be certain all operators of this equipment
have been trained for safe working practices, under-
stand it’s limitations, and wear safety goggles / equip-
ment when required.
CAUTION
Do not use the pump for the structural
support of the piping system. Be certain the system
components are properly supported to prevent stress
on the pump parts.
Suction and discharge connections should be flexi-
ble connections (such as hose), not rigid piped, and
should be compatible with the substance being
pumped.
CAUTION
Prevent unnecessary damage to the
pump. Do not allow pump to operate when out of ma-
terial for long periods of time.
Disconnect power supply from motor when system

4. GENERAL DESCRIPTION
4.1. Introduction
The EVO Series electric diaphragm pump offers a unique
combination of benets in the positive displacement pump
market. It features a broad range of material compatibility
options, high volume delivery, secondary containment, the
ability to fully deadhead, and is ecient and intelligent. The
pump works on the principle of converting rotary motion
from an AC induction motor to linear reciprocating motion to
drive a diaphragm. The motor is coupled directly to a rotating
eccentric crankshaft to drive connecting rods and pistons
which in turn drive three independent diaphragms. Three
diaphragms are used to ensure reduced pulsation and noise
for smoother and more reliable ow. Pump cycling will begin
as a commanded speed is supplied to the variable frequency
drive (VFD). As back pressure builds, the pump will reduce
speed until maximum line pressure is reached (dispensing
device closed). The pump will resume ow as back pressure is
relieved.
4.2. Storage
Place the equipment in a clean dry area, protected from im-
pacts, vibrations, temperature extremes and in an environ-
ment with relative humidity less than 90%.
When storing for longer than six months, consult the manu-
facturer.
4.3. Unpacking
Items supplied vary according to product conguration.
Make sure that the items supplied and the information on the
nameplate correspond to the order conrmation.
Check the individual packaging and the product visually for
damage caused by inappropriate handling during shipment.
NOTE: In-case of damage, report the damage to the transport
company and thereafter contact IR distributor.
NOTICE
To protect consumer rights please keep the Label intact on the
Motor, Pump and Drive.

5. MECHANICAL INSTALLATION
5.1. Pump and Motor Installation
WARNING
Pump and motors are industrial products. They
must therefore be installed by qualied, experienced and autho-
rized personnel. The safety of people, animals and property must
be ensured when tting the motors into pump.
CAUTION
Prior to commissioning for all motors, rotate
the motor at no load (no mechanical load) for 2 to 5 minutes,
checking that there is no abnormal noise. If there is any abnormal
noise, see section 5 on motor manual (Page 18).
WARNING
Before starting the motor, it is advisable to
check the insulation between the phases and earth, and between
phases.
Once Pump has been fully unpackaged and inspected, use
lifting points on Crankcase to move into nal operating posi-
tion (See Figure. 2).
Ensure straps and lifting device are properly rated. Refer
section 1.1 for pump weight.
All three lifting points should be used for stability.
Lifting points on Crankcase are intended to only move
the pump.
Do not use pump Manifolds to lift the equipment.
Ensure installation location has enough overhead room
to install motor vertically from above.
Ensure adequate clearance around pump for sufficient
access and ventilation.
Ensure the pump is installed on at level surface.
Secure pump legs to oor with M14 anchors.
Refer to section 13.1 for bolt circle spacing.
Pump must be positioned such that fluid inlet and fluid
outlet port are easily accessible.
Install motor onto the pump crank case.
Ensure gearbox motor does not damage pump Manifolds.
Refer to electric motor manual for lifting points and rec-
ommendations.
Ensure motor is vertical with shaft pointing downward
when mounting to the pump.
Ensure pump Crankshaft is greased from factory.
Motor should be carefully lowered while gently rotating
back and forth to ensure proper engagement of spline
interface. Ensure motor is aligned vertically. Do not apply
excessive force on the pump input Crankshaft. Spline in-
terface will t together easily with proper alignment.
Secure gearbox ange to Crankcase ange with 4X M12 (192)
bolts.

6.2. General Wiring Practice for VFD
Due to limited number of knockouts in VFD, it is recommended to combine signal wires (Safe Stop cable, Leak detector ca-
ble, Thermistor cable) into a single cable.
Route control wiring in separate conduit and as far away from power wires as possible.
A dedicated ground wire is needed, It is not recommended grounding through the conduit.
Keep wire runs as short as possible to help avoid problems.

imum stop level, which typically corresponds to 15% below the drive’s lowest rated supply voltage. Power-up and full torque cannot be expected at
mains voltage lower than 10% below the drive’s lowest rated supply voltage.
2. The unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 240/500/600 V maximum.
6.4. Power Wiring
6.4.1 VFD - Input Power Wiring
Size the wiring based on the input current of the drive (see page 3). For maximum cable cross-sections, see the table below
(from VFD manual, table 8.1.4)
Comply with local and national electrical codes for cable sizes.
Cable glands should be selected to match the cable diameter and to maintain the IP / Nema rating of the VFD.
Connect the 3-phase AC input power wiring to terminals L1, L2, and L3.
Ground the cable in accordance with the grounding instructions, see 4.3 Grounding and 4.5.1 Grounding the Cable Shield
in VFD manual.
When supplied from an isolated mains source (IT mains or oating delta) or TT / TN-S mains with a grounded leg (ground-
ed delta), ensure that parameter 14-50 RFI Filter is set to [0] O. This setting prevents damage to the DC link and reduces

6.5. Control Wiring (Required)
6.5.1. Leak detector wiring diagram
General Description:
An ARO Diaphragm pump equipped with the ARO Leak Detection Sensor warns of a Diaphragm failure by sensing the pres-
ence of liquid in the air cap of the pump. This system uses a liquid sensor in each of the three air caps which will send an out-
put signal to the VFD to shut down the motor when uid is detected.
Installation and Warnings:
NOTE: All WIRING MUST COMPLY WITH ALL LOCAL AND / OR NATIONAL ELECTRICAL CODES.
The Leak Detection Sensor components must be installed by a qualied electrician in compliance with all national, state
and local codes and regulations to reduce the risk of electrical shock or other serious injury during installation and opera-
tion.
Some local electrical codes may require the installation of rigid conduit.
ARO is not responsible for accidents resulting from improper installation of components or hardware.
Do not attempt any service without disconnecting all electrical supply source.

6.10. User dened readout
Parameters 030, 031, and 032 are available to modify the “User Dened Readout” that will display in the top left corner of
the main menu screen. By default, these values are set to scale motor frequency to actual pump rpm. To update the “User
Dened Readout”, refer to the following parameter descriptions.
1. Select the unit to be displayed on LCP from option given in parameter 030.
2. Minimum value is set to zero in parameter 031.
3. Maximum value is set for parameter 032 based on maximum motor frequency (92 Hz) set in parameter 414 and calcu-
lated as below.
Pump unit (Maximum) = Motor sync. RPM (1500) X Maximum motor frequency (92 Hz) x unit conversion factor (X)
“Motor Frequency (50 Hz) X GB ratio (12.7)”
Pump Unit (parameter 030) * Unit conversion factor (X)
RPM 1
Gallons per Minute 0.65
Liters per Minute 2.46
NOTE: Adjust unit conversion factor for the selected unit given in parameter 030 to calculate maximum value for parameter
032 per the above formula.
* Unit conversion factor values are approximate and depend on back pressure.
