6 Description and operation

6.1 Pump description

In order to ensure that the pump remains suffi-
ciently cool in continuous mode, the submersible
motor-driven pump must always be flooded with
the flow medium. The pump is driven by an
encased three-phase or single-phase motor

which is corrosion-resistant and impermeable to
pressurised water.
The pump housing and single-channel impeller
are made from grey cast iron. The flow medium is
sucked in on the underside of the pump through
the openings on the cutting device and is expelled
through the discharge side into the pipe.
The cutting device cuts up all dissectible constit-
uents so that they can be transported through the
single-channel impeller and the DN 40 pressure
pipe. The blades, cutters and counter-cutters are
made of hard metal. Constituents which cannot be
cut, such as stones or pieces of metal, damage the
cutting device and should therefore not be
allowed into the pump.
The motors are sealed from the flow medium by
means of a mechanical seal. Sealing from the oil
chamber is also by means of a mechanical seal on
types MTS 40 E..., where as a shaft seal is used on
types MTS 40/....
The oil chamber serves to cool and lubricate the
seals (see also 5.2).
CAUTION! Risk of leak!
If the mechanical seal is damaged, small quanti-
ties of oil may leak into the flow medium.
In addition to being connected by a foot bend
DN 40, the MTS 40 pumps can also be connected
to the pressure pipe using an elbow pipe (inner/
outer thread):
• Pressure pipe DN32 (1 ¼"):
MTS 40/95 - 120..., MTS 40 E 95 -120... using an
90° elbow pipe (inner/outer thread) 1 ¼".
• Pressure pipe DN40 (1 ½"):
MTS 40/95 - 165..., MTS 40 E 95 - 165... using an
90° elbow pipe (inner/outer thread) 1 ½" and
threaded flange with neck as per DIN 2566 with
inner thread 1 ½".
The motors are equipped with a winding protec-
tion contact (WSK) that automatically switches
off the motor if there is a threat of it overheating
and switches it back on again once it has cooled
down. On 3~motors, the winding protection con-
tact must be connected to the switchgear and
analysed there.
Within the motors of the MTS 40 E...(FM-
approved) pumps a leakage detector (DI) is
installed further away in the motor cavity which
indicates when water enters the motor.
