SAFETY INSTRUCTIONS

DESCRIPTION

CAREFULLY READ THE INSTRUCTIONS AND WARNINGS BEFORE STARTING TO OPERATE THE EQUIPMENT

Pumps with the mark

atmospheres according with 94/9/CE European Directive. This mark

assures that it is safe to operate the pump within the limitations

described in this manual.

A pump without the mark on it must never be used in a potentially

explosive atmosphere.

ATEX MARKING

The pump with this documentation must have a label as the one shown

above. This label includes the following information (this information is

only valid if the pump includes the label shown, if the label on the

pump is different, the following information does not apply):

PATENTED WORLDWIDE

PUMP TYPE:

PART No.:

YEAR: 2010

SERIAL No.:

MAX AIR / FLUID PRESSURE: 7 bar / 100 psi

FLUID IN/OUT:

Ex: Means that the pump can be used in a potentially explosive atmosphere.

II: Means the equipment group, for use above ground (non-mining

products).

2: Means product category.

USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES SPECIAL INSTRUCTIONS

WARNING: FOLLOW THE INSTRUCTIONS MENTIONED IN THIS CHAPTER TO AVOID RISKS OF SERIOUS INJURIES OR

DEATH AND DAMAGE OF THE EQUIPMENT AND ITS ENVIRONMENT.

• The information in this chapter is a complement to the information

provided in the pump manual. This chapter reoffers only to the

special cautions and procedures that shall be followed when working

in a potentially explosive atmosphere. Read always both manuals

before starting to use the pump.

• Always respect the working conditions for the pump mentioned in its

instructions manual.

• Pump installation, piping, commissioning, maintenance and repair

must be done by qualified personnel.

• Be sure that the pump is used following its marking and in approved zones.

• Be sure that the pump is well primed before start pumping flammable

or explosive fluids.

• Do not close the suction line and do not adjust pump speed or

operation acting on it.

• Check regularly for pump leaks.

• Always connect a ground wire, which must be attached to the pump.

• Never use the pump with non conductive fluids in atmospheres with

IIC gas.

• Maximum working temperature must always be observed. In normal

working conditions, the highest temperature on the pump surfaces

will correspond to the temperature of the pumped fluid marked up

with a safety factor to cover a spot temperature rise. The pump

follows norm EN 12463-1 for your safety. This norm limits temperature

for the gas present the potentially explosive atmosphere.

Pumps with the Ex mark on them have certain differences with other

pumps for complying with the requirements of the European

Directive 94/9/CE.

This instruction manual must be used together with the general

instructions manual for other pumps.

GD: Means that the pump can be used in a potentially explosive

atmosphere due to gas, mist or vapors (G) or dust (D).

IIB/IIC: Means the type of gas present in the potential explosive

atmosphere for which the pump is suitable. (IIB gas includes IIA gas).

95 ºC: Is the maximum working temperature for use with IIA and IIB gas.

Since the pump will never reach this temperature in normal working

conditions, this temperature represents the maximum fluid temperature for

a safe use with IIA and IIB gas. It is also the maximum temperature on the

pump or any other component surface. The pump surface maximum

temperature will always the fluid temperature if it is higher than 30 ºC.

Tech Ref: is the technical documentation reference and the notified

body that keeps it.

X: Means that there are special instructions conditions for the safe use

of the product mentioned in this manual (see chapter "Use in

potencially explosive atmospheres special instructions").

• Pump surface temperature will always be the fluid temperature

whenever it is higher than 30 ºC.

• Clean the pump regularly and remove all dust accumulation on its

surface when working in a potential explosive atmosphere.

• Be sure all elements are well connected before running the pump.

Always use flexible connecting elements and install pump on silent

blocks to avoid vibrations.

• Be sure valves at the pump inlet and outlet are open before running

the pump.

• Avoid the pump to run dry. Install a detection system like a low level

detector in the fluid storage tank.

• Maintain and inspect the pump regularly. Make sure the pump is

serviced according to the service instructions by a qualified repair

station. Use only original parts for servicing. Use of non original

parts will make the Ex approval invalid.

• Make sure that pump is placed in a safe location, with no risk of parts

or materials falling on it.

• The explosion protection certification marking on the pump refers

exclusively to the pump. All other assembled equipment should have

separate certification of at least the same or higher level of protection

as the pump.

• If a diaphragm beaks, the environment where the pump is installed

could became a potentially explosive atmosphere. If it occurs, stop

immediately the pump.
