Check the resistance list to ensure that assembled elastomers are suitable for the
pumped medium. ∗
∗∗
∗
Ensure the good assembly of the mechanical shaft seal as indicated by the supplier
(see technical specifications B-Series). ∗
∗∗
∗
Ensure the correct coolant for the mechanical shaft seal. Ignition temp.
of cooling water must be at least 50 K above the max. surface temp. of the pump
∗

∗
(EN 13463-5:2003 §4.5).
Ensure the correct coolant for the medium to be pumped.
Choice of seal only to be determine after consultation with the supplier.∗
∗∗
∗
• With extra guarantee against leakage
• Only when pumping volatile liquid.
• Apply safety device for coolant presence.
• (Only with Cat. 2 pumps)
Protect pump against temperature!
• (Only with Cat. 2 pumps)

With an Ex-pump (unit) supplied by BBA Pompen these aspects are ensured for the application
indicated by the client with the associated indicated medium.
Dangers relating to
the software:
It is the responsibility of the employer to ensure that the
safety measures (such as protection against temperature) and
the resulting action (such as the stoppage of the pump) are
appropriately included in the safety circuit.
The seal must be replaced in the following situations:
• If a seal leak occurs.
• If the seal develops heat.
• If the seal is exposed to a too high pressure
• If the seal is exposed to a too high temperature.
• If interaction has taken place with auxiliary liquid.
• If the pump has run dry for a protracted period
• If bearing surfaces of the seal show signs of running marks.
• If the pump bearings are worn.
• If different liquid is pumped to that for which the pump was originally purchased.
• If the seal has been damaged by a foreign object in the liquid.
6.2 Circulation systems: API 610/682
The B-Series optionally has the following systems:
• plan 2
• plan 11
• plan 12
• plan 21
• plan 31
6.2.1 Plan 2
The pump is prepared for the possible application of a plan system. On the delivery side in the pump
housing and at the place of contact surfaces of the mechanical shaft seal a hole is made for a system
possibly to be assembled later (see technical specifications B-Series).
