Section 4 - Essential Safety Requirements (ESR)
ATEX DIRECTIVE 2014/34/EU (EXPLOSION HAZARD SAFETY)
All FPL products that are certified to comply with the Directive also carry a specific ATEX Safety Manual
(Section 5) which must be referred to in conjunction with this manual. It is the responsibility of the user to
ensure that the equipment is correctly rated for the environment in which it is to be used.
When handling FPL products,please note weights given on FPL literature. Lifting equipment may be
required in certain cases.
Note that all pumps despatched from our works are tested with water and during storage,
packing and installation, some water will have remained in the pump body. This water may cause
spillage during handling. Water could react with the products you wish to pump,and it is your
responsibility to check this before putting the pump into operation. Water may also freeze if the pump
is exposed to sub zero temperatures. Do not operate the pump under these conditions as ice inside
the pump may cause damage to working parts of the pump.
At all times the installer must wear suitable clothing, footwear, goggles, etc for personal protection.
This particularly applies when the pump is being operated or maintained.
As with all double diaphragm pumps, it must be expected that diaphragm failure will occur without
warning and under these conditions, leakage of product can occur from the exhaust silencers unless a
guardian or barrier system is fitted (see Section 18).
If the product being processed is hazardous,then provision must be made by the user to deal with
this problem. This can be achieved by either specifying a guardian or barrier system as part of the
original pump specification or, as a retrofit from FPL works, or the silencers must be removed and
replaced by pipework which can carry the leakage to a safe place. Please note that wherever the
product is piped, pulses of mixed air and product will occur at the end of the pipework when diaphragm
failure has occurred. Provision must be made to accept the volumes of air/product mixture and the
pressures realised at that point.
If the product being pumped is corrosive or hazardous in any form, then provision must be made in the
piping construction to accept the mixed air/product that will be discharged under diaphragm failure
conditions.
Note the product may remain inside the pump after use and may be under pressure.
