7.4 Pumping station system (PS.S)
This section applies only to pumping station systems consisting
of Grundfos-approved components mentioned on the nameplate
of PS.S.
The pumping station system contains all the elements making the
pumping station function as one unit, and can contain the
following five elements:
• pit
• pump
• pump controller
• level controller
• accessories.
The pumping station system may not always have all five
elements. However, it will always have a pit and a pump, but the
pump controller or the level controller may be incorporated in the
pump, and/or accessories may be omitted.
7.4.1 CE approval of PS.S
PS.S is CE-approved in accordance with these directives and
standards:
• EN 2006/42/EC, EU Machinery Directive
• EN/ISO 12100, Safety of machinery - General principles for
design - Risk assessment and risk reduction.
To ensure safe transport and to fulfil customers' requests, the
PS.S elements can be assembled on site. But the CE approval of
PS.S is only valid if the following conditions have been fulfilled:
• PS.S has been assembled correctly in accordance with the
installation and operating instructions for PS.S and the pit,
pump and control systems.
• PS.S contains the Grundfos-specified elements stated on the
PS.S nameplate. The PS.S nameplate is fitted inside the pit.
7.5 Pumping station modular (PS.M)
PS.M is used instead of PS.S when the CE approval for the
complete system is not needed, or some of the components in the
pumping station, such as the controllers, are not supplied by
Grundfos.
A risk assessment for the complete system must be performed by
the customer, if necessary.
7.6 CE approval of PS.W and PS.S
PS.W and PS.S are CE-approved in accordance with these
standards:
• EN 12050-1
• EN 12050-2.
