4.11 Base
Centrifugal pumps can in principle be fixed on a foot, on a base, with a mounting flange in or on a tank, or
directly in a piping system. There are only limitations with respect to the size of the pump/pump unit and
the load-bearing capacity of the connected parts. An installed position with motor downwards is only
allowed with written approval from BBA Pompen BV. The base must be flat, must be provided with
sufficient fastening points, and must be able to withstand the load. With a pump unit with flexible
coupling the pump and motor shaft are aligned by BBA Pompen BV.
After the pump/pump unit has definitively been placed on the base, alignment must always be checked. If
pumps provided with an extra foot under the pump housing are used for higher liquid temperatures, the
bolts with which this foot is fixed to the base may only be lightly tightened to allow the expansion of the
pump.
Extra point(s) for attention with ATEX pumps.
K8.
Make sure you choose the right coupling.
• The coupling must be sufficient for the power and number of revolutions. ∗
• The coupling must itself be (Ex), and be able to be used in the appropriate zone and
temperature category. ∗
• The certificate for the coupling must be present. ∗
• Follow the instructions of the manufacturer (see technical specifications B-Series).
K9.
Ensure the correct design and material choice for the protective cover.
• No dangerous dust accumulation may take place. A design open at the bottom is
preferred. ∗
•
The protective cover must fit widely around the coupling in case of dents, and to make
no contact with any dust layer on the inside of the protective
cover. For cat. 2: choice of material no more than 7.5% magnesium (see EN 13463-
8.2) ∗
P3.
Make sure that the pump (unit) is mechanically well shielded while operating.
P4.
Make sure that the pump is installed without any stresses.

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.
