EXHAUST SAFETY WHEN PUMPING HAZARDOUS LIQUIDS

Suction Lift Installation

Flooded Suction Installation

Submerged Installation

In the event of diaphragm rupture, pumped material may enter the air end of the pump, and be discharged into the atmosphere. If pumping

a product which is hazardous or toxic, the air exhaust must be piped to an appropriate area for safe disposition.

WARNING!

Exhaust Safety

When a diaphragm fails during operation, pumped liquid can enter and contaminate the air side of the pump. If diaphragm

failure is not severe, i.e. a small split or hole, then the pump can continue to run, with air being forced into the product

being pumped. If however the failure is more serious, then the pump may stop, with uid or fumes being expelled through

the exhaust. Under these conditions it is recommended that exhaust is piped away to a safe area. In standard suction

lift conditions this can simply be done by piping from the exhaust connection to a safe area. Multiple installations can be

piped to a common connection, then to a safe area. In ooded suction exhaust is piped away above uid level.

In all conditions ensure exhaust outlet is not expelling across a non-conductive surface. The exhaust must not be placed

less than 100mm from any non-conductive surface, as this may generate a propagating brush

discharge resulting in a possible ignition source.
