thoroughly flushed with clean water. Rinse the pump parts in
water after dismantling.
8.1 Servicing Grundfos pumps with explosion-proof
motors
Only Ex-approved service centres are allowed to intervene in the
flameproof enclosure pump. Service not affecting the explosion
protection of the pump and not violating the Ex regulations may
be carried out by service persons who are not Ex-authorised.
Consequently, these persons are allowed to replace the following
parts of explosion-proof pumps:
• pump housing
• impeller
• seal ring and wear ring
•shaft seal.
All other service work must be carried out by an authorised Ex-
approved service centre. Violation of this requirement will
invalidate the Ex classification of the pump.
