Product description
S pumps, range 58
26
Cable entry
Watertight PA or cast iron cable entry with soft shape
and sealing rings to prevent damage of the cable or
leaks.
Sensors
As standard the pump is equipped with:
• Three thermal switches (Klixon), one in each phase.
• One moisture switch in terminal block.
Customised sensor options
1. WIO (water-in-oil) sensor
The WIO sensor measures the water content in the
oil and converts the value into an analogue current
signal. The two sensor conductors are for power
supply as well as for carrying the signal to the mea-
suring device or controller. The sensor measures
the water content from 0 to 20 %. It also sends a
signal if the water content is outside the normal
range (warning), or if there is air in the oil chamber
(alarm). The sensor is fitted in a stainless steel tube
for mechanical protection.
The WIO sensor is connected to the Grundfos
IO 111 module.
2. Bearing temperature sensor.
Testing
All pumps are tested before leaving the factory. The
factory test report is based on ANSI-HI centrifugal
pump test 1.6-2000, Acceptance level B. Test reports
can be ordered directly with the pump or can be ordered
separately based on the pump serial number.
Other tests or third party inspection certificates are
available on request including HI B & A standards.

Operating conditions
Pumps without cooling jacket in submerged
installation:
• Continuous operation when pump is fully sub-
merged to top of motor.
• Intermittent operation with max. 20 starts per hour
when pump is submerged to middle of motor and
with short periods of operation down to the top of
the pump housing
Note:
Explosion proof pumps must always be fully
submerged
Pumps with cooling jacket in submerged and dry
installation:
• Continuous and intermittent operation with max. 20
starts per hour with water level down to the top of
the pump housing.
Pumped liquids
pH value:
4-10
Liquid temperature:
32 °F - 104 °F (0 °C - +40 °C)
When pumping liquids with a density and/or a kinematic
viscosity higher than that of water, use motors with
correspondingly higher outputs.
Sound pressure
The sound pressure level of the pump is lower than the
limiting values stated in the EC Council directive 2006/
42/EC relating to machinery (the EC Machinery
Directive).
