1. General description

This booklet includes instructions for installation, operation and
maintenance of Grundfos submersible wastewater pumps, types
S1 and SV, fitted with motors of 1.65 to 5 kW.
The booklet also includes specific instructions for the explosion-
proof pumps.

1.1 Applications

The S1 and SV pumps are designed for the pumping of wastewa-
ter in a wide range of municipal, private and industrial applica-
tions.
The pumps are suitable for submerged or dry installation.
Maximum solids size: 80 mm or 100 mm.
1.1.1 Potentially explosive environments
In potentially explosive environments, the explosion-proof S1 and
SV pumps must be used, see sections 1.5.1 Ex certification and
classification and 7.3 Explosion-proof S1 and SV pumps.
Note: The explosion classification of the pump is Ex dIIB T3 or Ex
dIIB T4. The installation must in each individual case be approved
by the local fire-fighting authorities.
Note: Only pumps classified EXd IIB T3 may be used for fre-
quency converter operation. The maximum frequency is 60 Hz,
but the P1 value stated on nameplate must not be exceeded.

1.2 Operating conditions

1.2.1 pH value
All pumps can be used for pumping liquids with a pH value
Page
between 4 and 10.
6
1.2.2 Liquid temperature
6
0°C to +40°C.
6
6
1.2.3 Ambient temperature
7
-20°C to +40°C.
8
1.2.4 Density and viscosity of pumped liquid
8
9 Maximum density: 1000 kg/m
9 Maximum kinematic viscosity: 1 mm
10
Note: When pumping liquids with a density and/or a kinematic
10
viscosity higher than the values stated above, motors with
10
correspondingly higher outputs must be used.

1.2.5 Level of pumped liquid
11
In the case of submerged pump installation, the lowest stop level
11
must always be above the pump housing.
11
• Installation type S:
11
The motor must always be covered by the pumped liquid.
12
• Installation type C:
12
The pump housing must always be covered by the pumped
12
liquid.
12
• Installation type D:
13
No special requirements.
13
14
The pump must always be filled with the liquid to be
15
pumped.
An additional level switch must be installed to ensure
that the pump is stopped in case the stop level switch
is not operating.
1.2.6 Operating mode
The pumps are designed for continuous operation or for intermit-
tent operation with the maximum 25 starts per hour.
1.2.7 Enclosure class
IEC IP 68.

1.3 Sound pressure level

The sound pressure level of the pump is lower than the limiting
values stated in the EC Council Directive 98/37/EC relating to
machinery.
