Maintenance, service and repair
SRP pumps must only be serviced by Grundfos or an authorized
service workshop. This also applies to the cable entry. Use only
components produced by Grundfos for repair purposes.
Service log
Spare parts etc. must be registered in a service log in order to
have a 100 percent traceability during the product life.
5. Transportation, delivery and storage
5.1 Transportation
The individual components of the pump must be packed carefully
to prevent any damage to the surface protection during
transportation.
All lifting equipment must be rated for the purpose and checked
for damage before any attempts to lift the components are made.
The lifting equipment rating must under no circumstances be
exceeded.
5.2 Delivery
On delivery, the pump and any accessories supplied with it
should be checked for transport damage. This also applies when
the equipment is delivered to the installation site.
If the pump or any accessories have been damaged during
transportation, contact your local Grundfos company before
continuing to install the equipment. Do not dismantle a damaged
new component for further inspection, unless instructed by your
local Grundfos company.
The packaging material must be disposed of according to local
regulations.
5.3 Storage
The pump must be stored in a dry location in which the
temperature is not subject to major fluctuations.
If the pump has been stored for more than one year, the gearbox
oil must be changed. The oil must be changed even if the pump
has never been in use. This is necessary because of natural
aging of mineral oil lubricants.
6. Installation
During installation, the pump must only be lifted when using the
suspension point.
The lifting equipment supplied with the pump as well as the wire
used for lifting and lowering the pump into the tank must not be
used as universal lifting equipment.
6.1 Positioning
Correct positioning of the pump is essential to ensure trouble-free
operation and long life. The following guidelines must be
observed:
• If more pumps are installed in the same tank, they must not
generate opposite flows.
• The distance from the centre of the pump to the tank bottom
(H
min
) must be equal to the impeller diameter. See fig. 4.
• The distance from the top of the pump rack to the liquid
surface (H
ABOVE
) must fulfil one of the following two
requirements:
– For pumps with vortex shield, the distance must at least be
equal to the impeller diameter.
– For pumps without vortex shield, the distance must at least
be equal to 1.5 times the impeller diameter. See fig. 4.

Guide claws are only available for SRP.xx.80.
Warning
Make sure that the pump cannot roll or fall over.
Warning
Before attempting to lift or otherwise handle the
individual components of the pump, observe any
local regulations that set limits for the weight of
the components to be lifted manually by
individuals, i.e. handled without the use of lifting
equipment.
Warning
A damaged pump must not be installed.
Note
Never hang the pump by the supply cable.
Never let the pump run while hanging in the
lifting equipment.
