Temperature Sensor
All pumps are equipped with a temperature sensor
assembly in each motor winding.
In standard pumps, the connections for the temperature
sensor are fed via the power cable to the outside and are
to be connected in the electric control box using the T1
and T3 power cable endings in such a way that the motor
automatically restarts after it has cooled down. Instead
of the standard sensor, the explosion-proof versions are
equipped with a temperature sensor assembly that has a
higher activation temperature. This is to be connected via
the power cable endings T1 and T2 in such a way that after
activation, a manual reset in the switchgear is necessary
using a special contactor combination The temperature
sensor assembly must be connected in the switching
cabinet so that it switches off when it overheats.

Seal monitoring for non-jacketed pumps:
In case of a leak in the lower shaft seal, water enters the
oil chamber and changes the resistance of the oil. The con-
ductivity of the oil is monitored via 2 sensors. The sensors
are to be connected via one cable to ground, or 2 cables
(consult wiring diagram) from the pump connection cable
in the junction box to an evaluation instrument galvanically
separated from the probe circuit. The response sensitivity
should be adjustable from 0-100 kΩ, the standard setting
being 50 kΩ.
3.3.4. Sealing / Seal Housing
Sealing is accomplished by two silicon carbide mechani-
cal seals in a tandem arrangement, acting independently
from each other. The seal housing is situated between the
motor and the pump housing. It consists of the bearing
housing and the pressure cover, which together form the
sealing cavity containing white mineral oil. Oil condition
may be monitored using the inspection plug on the bear-
ing housing and optional electronic monitoring.
3.3.5. Volute
The pump may be equipped with a stationary wear ring
which can be found in the intake port.
This wear ring deter-
mines the gap between the impeller and the intake port. If
this gap is too big, the performance of the pump decreas-
es and it can lead to blockages. The rings can be replaced
due to wear. Discharge connections for TP30 & TP49 mod-
els are 2” Male Metric Straight Thread, an adapter (avail-
able as standard) is required to connect to NPT fittings.
TP50 models have both 2 ½” Male Metric Straight Thread,
and 2” Female NPT connections.
TP53 & TP70 models have 3” Male Metric Straight Thread
connections, and require an adapter (available as stan-
dard) to connect to NPT fittings.
3.3.6 Impeller
M:
Enclosed single channel impeller, for liquids containing
impurities and sludge with solid particles or long fibres.
V:
Vortex impeller, for liquids containing a high level of
impurities or fibrous matter and containing gas.
4. Package, Transport, Storage
4.1. Delivery
On arrival, the delivered items must be inspected for dam-
age and a check made that all parts are present. If any
parts are damaged or missing, the transport company or
the manufacturer must be informed on the day of delivery.
Any claim made at a later date will be deemed invalid.
Damage to parts must be noted on the delivery or freight
documentation.
4.2. Transport
Only the appropriate and approved fastening devices,
transportation means and lifting equipment may be used.
These must have sufficient load bearing capacity to en-
sure that the product can be transported safety. If chains
are used they must be secured against slipping.
The personnel must be qualified for the tasks and must
follow all applicable national safety regulations during the
work. The product is delivered by the manufacturer/ship-
ping agency in suitable packaging. This normally precludes
the possibility of damage occurring during transport and
storage.
Never lift the pump by its power cable!
