4.0 Instructions for assembly and disassembly
4.1 General
Insufficient or wrong assembly and disassembly can lead to the pump malfunctioning, high repair
costs and long-term inoperability. Contact your distributor for information.
Disassembly and assembly may only be carried out by trained personnel. Such personnel should be
familiar with the pump and follow the instructions below.
Non compliance with the instructions or neglecting warnings can harm the user or lead to severe
damage to pump and/or pump unit. SPX Process Equipment is not liable for accidents and damage
resulting from such neglect.
Because of the presence of strong magnetic fields there are special safety instructions
which must be observed.
Personnel who carry a cardiac pacemaker should not be allowed to work on a pump equipped with
magnetic coupling!. The magnetic field is sufficiently strong to affect the proper operation of a pace-
maker, so keep a safe distance of at least 3 m.
Do not come close (not less than 1 m) to the magnetic coupling with objects equippid with magnetic
data carrier such as cheque cards, computer disks, watches etc. to avoid damage and/or loss of
information.
Do not subject the pump to any jolting loads. This can cause damage to the magnets or the slide
bearings of the rotor shaft on account of their brittleness.
