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.
