Revision 4.4 / November 2010

5.11 Maintenance / Repair
• The Filling of the pump is only permitted outside the explosion aria. Tools that are used should in compliance with
ATEX.
• The pump aggregate always needs to be kept clean of dust with a damp cloth to prevent the dust from smouldering.
• The rinsing channels in the power frame must always be checked for blockages and if necessary cleaned.
5.12 Cleaning
Caution! No solvent cleaning agents may be used to clean the pump as this could create an uncontrollable explosive
atmosphere.
5.13 Medium to be pumped
Chemicals that are combustible below the temperature 120 degrees Celsius (T4/T=120°C) and Carbon disulphide must not be
pumped.
5.14 Coupling
If the pump is used in an explosion-risk area, the pump must only be coupled to the drive by means of an elastic, positive
coupling with ATEX certification, at least corresponding to the supplied pump. Chains, toothed belts, v-belts or similar equipment
which may transmit radial forces on the bearings should not be used.
5.15 Drive
Any preceding reduction gears and/or control units must have the corresponding ATEX certification, at least corresponding to
the supplied pump. Combustion engines must never be used!
For operation with a frequency converter, this must either be installed outside the ex-zone, or have the same ATEX certification
corresponding to the delivered pump. In any case the converter must have the properties required for operation in ex-zones, for
example, temperature monitoring, speed limitation, etc.
6 Warranty and liability
Basically our “General sales and delivery conditions” apply.
These are available to the operator at the latest since conclusion of the contract.

devices
- Non-compliance with the instructions in the operating instructions regarding
transport,
storage,
installation,
start-up,

7 Transport instructions
The choice of the means of transport is according to the size of the pump and of the drive. The pump must be suspended
correctly for transport. The crane/forklift truck and the ropes/belts must be sufficiently dimensioned. If the pump is transported
with a lift truck or a forklift truck, it must be noted that the console centre point is not automatically the centre of gravity.
