7. 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.
8. 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.
9. Materials
Although being allowed as material for the pumps, aluminum should be avoided in
potentially explosive areas.
The pumps may only be used if, under the particular operating conditions, the
materials are resistant to mechanical and/or chemical influences or corrosion such that
the explosion protection will be maintained.
10. Gland
If a gland packing is applied it has to be observed that the permitted temperature
corresponding to the temperature category is not exceeded. Recommendation: fasten
the screws of the stuffing box gland only with low torque (approx. 5 Nm).
11. Dust layer
No dust layer of more than 5 mm is allowed on the pumps. Rotating parts (like drive
shaft, bearing carrier and drive stool of paddle agitators) must not run in a dust layer.
In respect of this the pumps have to be controlled at regular intervals and if necessary
the dust has to be removed.
