The connection to ground is to be maintained until the pump has been
completely pulled out of the container.
There must not be any potential difference between the pump and
a conductive container. This means that container and pump are to be
connected at a common grounding point and thus be conductively
connected with each other.
(see information brochure "Statische Elektrizität, Zündgefahren und
Schutzmaßnahmen" (Static electricity, dangers of ignition and preventive
measures); Publisher: "Internationale Sektion für die Verhütung von
Arbeitsunfällen und Berufskrankheiten in der chemischen Industrie der IVSS"
(International section for the prevention of employment accidents and
occupational diseases in the chemical industry of the ISSA (International Social
Security Association)) , Heidelberg 1995).
The hand-operated movable immersion pumps are to be provided with an
indication referring to the grounding measure (pay attention to grounding).
7. Potential equalization concerning all other pump types (no immersion pumps)
All conductive parts of the pump are to be integrated in the potential
equalization of the pumping set unless the conductive connection to
the ground potential is guaranteed by the drive or connecting shafts
or otherwise.
8. Stator
The stator is to be regularly checked for wear. When the allowable
wear limit is reached, the stator is to be replaced. Before exchanging
the conveying product, the pump operator has to consult the
manufacturer concerning the durability of the stator unless the stator
has already been confirmed for the intended application.
Inspection and maintenance interval of the stator:
– in the case of an operating time of > 16 h/day, at least twice a year
– in the case of an operating time of < 16 h/day, at least once a year.
9. Joints / joint lubrication
The sealing and the lubrication of the joints are to be regularly checked.
If necessary, the seals and the lubricants are to be replaced.
Inspection and maintenance interval of the joints:
– in the case of an operating time of > 16 h/day, at least twice a year
– in the case of an operating time of < 16 h/day, at least once a year.
10. Inspection after initial startup
The aspects relevant for ensuring the explosion protection (such as
lubrication and wear check) are to be checked six months after the
initial startup of the pump at the latest.
