Before beginning installation procedures,
these installation and operating instruc-
tions should be studied carefully. The in-
stallation and operation should also be in
accordance with local regulations and ac-
cepted codes of good practice.
1. General description
1.1 Applications
GRUNDFOS AP30 pumps are designed for pump-
ing:
• wastewater,
• sludge-containing water,
• groundwater,
• surface water.
AP 30 pumps can handle solids up to 30 mm in
diameter.
The compact design makes the pumps suitable for
both temporary and permanent installation. Further-
more, the pumps are suitable for free-standing instal-
lation as well as installation by means of an auto-
coupling guide rail system.
1.1.1 Explosive environments
Use the explosion-proof AP pump versions for appli-
cations involving the risk of explosion.
Note: In each individual case the explosion classifi-
cation of the pump must be approved by the local
authorities for use at the desired installation site.
1.2 Operating conditions
1.2.1 pH-value
AP pumps in permanent installations can cope with
pH-values ranging from 4 to 10.

1.2.2 Liquid temperature
Liquid temperature: 0°C to +40°C.

For short periods up to +60°C.

1.2.4 Installation depth
4
Maximum 10 metres below liquid level.

1.2.5 Level of pumped liquid
4
5
The lowest stop level must always be above the top
5
of the pump housing.

1.2.6 Operation
5
5
Maximum 15 starts per hour.
6
Note: The pumps are designed for intermittent oper-
6
ation only.

1.3 Sound pressure level
7
The sound pressure level of the pump is lower than
7
the limiting values stated in the EC Council Directive
7
98/37/EEC relating to machinery.
2. Safety
Pump installation in wells must be carried
out by specially trained persons.
3. Transportation and storage
The pump may be transported and stored in a verti-
cal or horizontal position. Make sure that it cannot
roll or fall over.
Always lift the pump by its carrying handle, never by
the motor cable or the hose/pipe.
For long periods of storage, the pump must be pro-
tected against moisture and heat.
After a long period of storage, the pump should be
inspected before it is put into operation. Make sure
that the impeller can rotate freely. Pay special atten-
tion to the shaft seals and the cable entry.
4. Installation
Prior to installation, check the oil level in the oil
chamber, see section 7. Maintenance and service.
4.1 Installation on auto-coupling
See figs. A and B, pages 54 and 55.
Pumps for permanent installation can be installed on
a stationary auto-coupling and operated completely
or partially submerged in the pumped liquid.
1. Drill mounting holes for guide rail bracket on the
inside of the pit and fasten the guide rail bracket
provisionally with two screws.
