4. Product and accessory description

4.1 Pump description (Fig. 1)
The submersible motor-driven pump is normally submerged by
the flow medium. It is driven by an encased rotary current motor
which is impermeable to pressure water. The motor is sealed with
a sheet steel cooling jacket (pos. 1). With this, the heat from the
motor is dissipated when the pump protrudes from the flow fluid.
The coolant is the flow fluid which is compressed through a
narrow passage between the pump housing and the impeller.
The pump housing and the impeller are made of a synthetic
material. The flow medium seeps upwards from a central opening
(DN 80, DN 100 or DN 125) and flows out of the pressure support
at the side, DN 80, DN 100 ou DN 125.
The pump may be fitted with various types of impellers
(Pos. 2 a,b,c):
The single channel impeller (pos. 2a) takes the form of a single
spiral with a free, large passage. It is used for waste water
containing solid waste, sewage and sludge.
The multi-channel impeller (pos. 2b) differs from the single
channel impeller in that it has two mirror-inverted spirals.
The (VORTEX) impeller (pos. 2c) has short, radially-aligned
blades which are only immersed approximately 1/3 of the turbine
chamber height in the liquid current. This impeller is used for gas-
charged liquids or waste water containing long-fibred solids.
The motor is sealed against the pump housing by 2 mechanical
seals (pos. 3 and 4). The space between the seals (pos. 5) is
filled with a water-glycol mixture (40 % glycol) so that the upper
seal (pos. 4) is lubricated and becomes cool. It was filled when
the pump was assembled.
The pump is protected against overstress by a thermal winding
contact (WSK). A leakage control sensor (DI) is installed further
away in the motor cavity which indicates when water enters the
motor.
Because of their construction, the safe

operation of the protective devices referred
to is only guaranteed with the Wilo Drain-
Control switchgear (accessory). All other
switchgear must be supplemented with the
SK 545 monitoring device (accessory). No
guarantee may be assumed for damage to
the winding which is due to unsuitable motor
monitoring for this very reason.
When assembled as a stationary pump, it is connected by a
coupling foot (on the pressure side) or with flanges at the suction
and pressure pipes. If the pump is transportable, it is fastened on
the pressure side to a hose coupling.

5. Assembly/installation
The pumps of series TP 80, TP 100 and TP 150 are intended for
the following types of installation
– transportable wet-well installation
– stationary wet-well installation
– stationary dry installation (horizontal and vertical)
For the planning and operation of waste water installations,
please refer to the appropriate local regulations and directives of
the municipal sewage system (e.g. Waste Water Association ATV).
With stationary installations in particular, reference is made to
pressure surges which may occur in the event of pumping with
long pressure pipes (especially in the case of a constant gradient
or pronounced ground profile). Pressure surges can destroy the
pump / installation and may involve excessive noise due to the
closing of flaps, which can be avoided by employing suitable
measures (e.g. flap traps with adjustable closing time, special
laying of the pressure pipework).
5.1 Assembly
– The pump must be installed in a frost-free place.
– The shaft must be free from coarse solids (e.g. building
rubble) prior to installation and commissioning.
– A hoist is necessary for the transportation of the pump to the
location where it is to be installed. The hoist should be set up
on the premises.
The pump should only be hung on the
ATTENTION!
eyebolt.
– "Original Wilo accessories" are recommended to ensure the
fault-free operation of the pump / installation.
When assembling the connections on the
ATTENTION!
suction side and pressure side flanges, the
depth of the blind hole threading should be
observed (fig. 3). The chucking torque
should be 25 Nm maximum. The enclosed
o-rings/ seals should be used. Screws which
are too long cause a hollowing out of the
insert nut.
The size of the threading and maximum screw length for the
flange screws are as follows (fig. 3):
Type of pump Flange screws
TP 80 M 16
TP 100 M 16
TP 150 M 20
– The 80mm minimum clearance between the pump and the
ground must be respected.
– The water level ( min ) (Fig. 2b, 2c, 2d) must not sink below
¨
the upper edge of the pump chamber. The control level should
be adjusted to this minimum level.
Failure to comply with these regulations may result
in loss of protection against explosion.
The pump must not run dry for more than 5

minutes. The pump is protected against dry
running through the use of Wilo switchgear
with type-N level indicators (see Acces-
sories).
