Delivery

WARNING
Crushing of feet
Death or serious personal injury
- Stack the pumps with the biggest at the bottom,
and do not stack above 1 m.
- Use lifting equipment which is approved for the
weight of the product.
- Wear personal protective equipment.
WARNING
Crushing of hands
Death or serious personal injury
- Stack the pumps with the biggest at the bottom,
and do not stack above 1 m.
- Use lifting equipment which is approved for the
weight of the product.
- Wear personal protective equipment.
The pump must remain in the packing until it is
placed in vertical position during installation.
Handle the pump with care.
When the pump part and motor are supplied as separate units
(long pumps), fit the motor to the pump as described in section
7.1 Fitting the motor to the pump.
The extra nameplate supplied with the pump must be
fixed at the installation site.
Do not expose the pump to unnecessary impact and shocks.
3.2 Storage
Storage temperature
Pump: -20 - +60 °C.
Motor: -20 - +70 °C.
The motors must be stored in a closed, dry and well ventilated
room.
If MMS motors are stored, the shaft must be turned
by hand at least once a month. If a motor has been
stored for more than one year before installation, the
rotating parts of the motor must be dismantled and
checked before use.
The pump must not be exposed to direct sunlight.
If the pump has been unpacked, it must be stored horizontally,
adequately supported, or vertically to prevent misalignment of the
pump. Make sure that the pump cannot roll or fall over.
During storage, the pump can be supported as shown in fig. 1.

3.2.1 Frost protection
If the pump has to be stored after use, it must be stored on a
frost-free location, or the motor liquid must be frost-proof.

4. Applications

Grundfos SP submersible pumps are designed for a wide range
of water supply and liquid transfer applications, such as the
supply of fresh water to private homes or waterworks, water
supply in horticulture and agriculture, drawdown of groundwater
and pressure boosting, and various industrial jobs.
productDelivery and The pump must be installed so that the suction interconnector is
completely submerged in the liquid. The pump can be installed
horizontally or vertically. See section

4.1 Pumped liquids

Clean, thin, non-explosive liquids without solid particles or fibres.
The maximum sand content of the water must not exceed
3
50/100/150 ppmg/m . A larger sand content will reduce the life of
the pump and increase the risk of blockage.

of water, motors with correspondingly higher outputs
must be used.
If liquids with a viscosity higher than that of water are to be
pumped, contact Grundfos.
The pump versions SP A N, SP A R,
are designed for liquids with higher aggressiveness than drinking
water.
The maximum liquid temperature appears from section

4.2 Sound pressure level

The sound pressure level has been measured in accordance with
the rules laid down in the EC machinery directive 2006/42/EC.
