3.4 Storing the product

The contractor must inspect the equipment on delivery and make
sure that it is stored in such a way that corrosion and damage are
avoided.
If more than six months will pass before the equipment is put into
operation, please consider applying a suitable corrosion inhibitor
to the internal pump parts.
Make sure that the corrosion inhibitor used does not affect the
rubber parts with which it comes into contact.
Make sure that the corrosion inhibitor can be easily removed.
To prevent water, dust, etc. from entering the pump, all openings
must be kept covered until the pipes are fitted. The cost of having
to dismantle the pump during startup to remove foreign objects
can be very high.
