Safety; Receiving The Product; Transporting The Product; Contaminated Pumps - Grundfos S Series Service Instructions Manual

2. Safety

Pump installation in pits must be carried out by
specially trained persons.
Work in or near pits must be carried out according to
local regulations.
For safety reasons, all work in pits must be supervised by a
person outside the pump pit.
Pits for submerged sewage and wastewater pumps contain
gasses and wastewater with toxic and/or disease-causing
substances. Therefore, all persons involved must wear
appropriate personal protective equipment and clothing, and all
work on and near the pump must be carried out under strict
observance of hygienic regulations in force.
DANGER
Crushing hazard
Death or serious personal injury
- Before attempting to lift the pump, make sure the
rated capacity of the lifting equipment (lifting chain
etc.) is adequate for the lifting work. The rated
capacity of the lifting equipment is stated on the
equipment nameplate. The weight of the pump is
stared on the pump nameplate.
WARNING
Crushing of feet
Death or serious personal injury
- Always lift the pump by its lifting bracket or by
means of a fork-lift truck.

3. Receiving the product

3.1 Transporting the product

You can transport the pump in vertical or horizontal position.
Make sure that the pump cannot roll or fall over.
During long periods of storage, the pump must be protected
against moisture and heat.
For further information, see the installation and operating
instructions for S pumps, range 50-70. The installation and

3.2 Contaminated pumps

CAUTION
Biological hazard
Minor or moderate personal injury
- Flush the pump thoroughly with clean water and
rinse the pump parts in water after dismantling.
If a pump has been used for a liquid which is injurious to health or
toxic, the pump will be classified as contaminated.

4. Handling the pump

S pumps weigh up to 2375 kg without accessories. It is therefore
very important to use the right lifting equipment.
The pump weight is stated on the pump nameplate. See section
5.1 Nameplate.

4.1 Lifting the pump

All lifting equipment must be rated for the purpose and checked
for damage before any attempt to lift the pump. The lifting
equipment rating must under no circumstances be exceeded. See
section
7.4 Lifting tools.

4.2 Lifting points

DANGER
Electric shock
Death or serious personal injury
- Never lift the pump by the power supply cables.
Lifting the pump by the power supply cables may result in electric
short circuit and risk of electric shock when the pump is
connected to the mains. The cables and the cable entry may be
damaged, leading to loss of watertightness and consequent
severe damage to the motor.
4.2.1 Lifting points (top)
Use the right lifting point to keep the pump balanced. S pumps
are equipped with a lifting bracket with lifting points ensuring that
the pump can be lifted in a safe manner. See fig.
