Safety Instructions For Inspection And Installation Work; Modification Of Equipment And Use Of Spare Parts; Improper Use; Pumpset Delivered Without Motor - salmson NOLH Installation Et Mise En Service

ENGLISH
Operating the pump at lower flow rates may cause a reduction of
ball bearings/bearing lifetime, overheating in pump sealing
chamber, instability and cavitations/vibration.
Never remove protecting covers or coupling guard when pump is
ready to run. Those parts can only be removed during
maintenance operations.
2.5 SAFETY INSTRUCTIONS FOR INSPECTION
AND INSTALLATION WORK
The operator must ensure that all inspection and installation work
are carried out by authorized and qualified personnel. The
operators must be sufficiently informed and must know the content of
these instructions and of the incorporated materials instructions before
any operation is carried out on pumps and accessories.
Access to the product must only be carried out when pump is at a
standstill. It is mandatory that the procedure described in the
installation and operating instructions for shutting down the pumpset
are fully respected.
All protections and security devices must be reactivated or
switched on immediately after works are ended.
2.6 MODIFICATION OF EQUIPMENT AND
USE OF SPARE PARTS
Modifying the product is only permitted after agreement of Salmson.
Use of genuine spare parts and accessories authorized by the
manufacturer ensure safety and proper work of the pump.
2.7 IMPROPER USE
The operating safety of the product is only guaranteed for conventional
use and in accordance with the technical offer and this operating
instructions. The limit values indicated in the relevant catalogue/data
sheet must not be exceeded.
2.8 PUMPSET DELIVERED WITHOUT MOTOR
When pumpset is delivered without any motor (a CE integration
certificate has been supplied with the pump) it is the end‐user's
responsibility to ensure that all regulation requirements are respected
to get a CE marking.
Certification of the complete pump set will be from integrator
responsibility. He will ensure that aIl specifications listed in this
instructions are fully respected.
2.9 SECURITY INSTRUCTIONS
APPLIED ON EQUIPMENTS USED IN
POTENTIALLY EXPLOSIVE ATMOSPHERE
This chapter contains operating instructions that have to be
considered when using the pump in a potentially explosive
atmosphere. The ATEX additive supplied with the pump will be
considered as well.
This chapter indicates supplementary instructions to :

Avoid excessive surface temperature,

Avoid build up of explosive mixture,

Avoid sparks creation,

Prevent leakages,

Ensure proper maintenance to avoid hazard.
The following instructions for the pump and pump units shall be
followed when the equipment is installed in a potentially explosive
atmosphere. Ex‐proof protection is ensured only if the pump unit and
supplied accessories are installed according instruction given in this
instruction and operating manual. Both electrical and non‐electrical
equipment must meet the requirements of European Directive ATEX
94/9/EC.
2.9.1 SPECIFIC MARKING INSTRUCTIONS FOR
ATEX
All manuals and user guides at all-guides.com
TO BE
6
An example of ATEX equipment marking is shown hereunder for
information. Dedicated ATEX classification is engraved on pump
nameplate and indicated in the ATEX additive :
II‐2Gc(x)‐Exd‐IIBT4
With :
EQUIPMENT GROUP :
II = Non‐mining
CATEGORY :
2 = high protection (zone 1)
3 = normal protection (zone 2)
GAS or DUST :
G = Gas
Those pumps are not « D » Dust certified.
PUMP PROTECTION :
c = safe by construction
X = respect special instruction for equipment integration
MOTOR ENCLOSURE :
Exd = flameproof
Exd(e) = flameproof frame and increased safety junction box
GAS GROUP :
IIA ‐ Propane
IIB ‐ Ethylene
IIC ‐ Hydrogen
MAXIMUM SURFACE TEMPERATURE (Temperature class to ATEX
94/9/EC) :
T1 = 450°C
T2 = 300°C
T3 = 200°C
T4 = 135°C
T5 = 100°C
T6 = 85°C
T(x) = variable temperature or pump used in several areas.
2.9.2 FLUID TEMPERATURE
Ensure that the equipment temperature class is suitable for the
hazard zone. It is the plant operator's responsibility to select the
Atex zone in which the pump is installed.
Pump temperature class is as stated on the nameplate. It is based on a
maximum ambient temperature of 40°C. (ask SALMSON for use in higher
ambient temperatures).
The surface temperature taken on pump surface is influenced by the
temperature of the handled liquid. The maximum permissible
temperature depends on the ATEX temperature class and must not
exceed the values indicated in the ATEX additive attached to the pump.
The shaft seal and bearings temperature rise due to the minimum
permitted flow rate are taken into account.
The maximum fluid temperatures indicated below are given
accordingly :
T1  400°C
T2  275°C
T3  180°C
T4  115°C
T5  80°C
T6  need SALMSON approval
If there is a risk to run the pump on a closed discharge valve it is
requested to monitor surface temperature. Motor overload trips
should be correctly calibrated. Proceed with regular cleanings if pump is
installed in dirty or dusty environment.
2.9.3 BUILD UP OF EXPLOSIVE MIXTURE
Ensure that pump casing and mechanical seal chamber are
correctly vented and that pump will not run dry.
