In order that the shaft sealing can be monitored
and maintained unhindered, no protection cover
is provided in this area. Therefore special atten-
tion is required when pump is working (no long
hair, loose clothes, a.s.o.).
ƒ Packing:
Packings need leakage for troublefree function
(dropwise outlet of pumped medium). Adjust am-
ple leakage in the beginning. Reduce that slowly
during the first operating hours by continuously
fastening of gland (see position "452" and
"920.31" in sectional drawing) when pump is run-
ning. Assume 30-100 drops / minute as approx.
value.
Dry running packings harden and destroy the
shaft sealing resp. the shaft.
If pump does not reach attended head or if
atypical sounds or vibrations do occur:
Switch off pump (see chapter 6.7) and seek for
causes (see chapter 10).
6.3 Restarting
Basically, the same procedure should be followed as
for starting up for the first time. However, there is no
need to check the direction of rotation and the acces-
sibility of the pump unit.
The pump should only be automatically restarted if it
has been made sure that the pump has remained
filled whilst stand by.
Be particularly careful not to touch hot machine
parts and when working in the unprotected
shaft seal area. Remember that automatically
controlled systems may switch themselves on
suddenly at any time. Suitable warning signs
should be affixed.
6.4 Limits of Operation
The operating limits of the pump / unit regarding
pressure, temperature, performance and speed
are shown in the data sheet and / or order con-
firmation and must be observed under any cir-
cumstances!
ƒ Do not exceed the output given on the motor
name plate.
ƒ Avoid sudden changes in temperature (tempera-
ture shocks).
ƒ The pump and motor should run evenly and with-
out vibrations; check at least once a week.

6.4.2 Abrasive Media
On pumping liquids with abrasive components
an increased wear at hydraulic and shaft seal-
ing must be expected. The intervals of inspec-
tion should be reduced compared to the usual
times.
6.4.3 Permitted number of starts
The permitted number of starts of the pump must not
be exceeded, see diagram 6.

With electric motors, the permitted number of starts is

6.5 Lubrication of Bearings
6.5.1 Oil lubrication
The bearing bracket must be filled up with oil.
For quality of oil refer to chapter 7.4.1.
For qantity of oil refer to chapter 7.4.1.
The pumps are delivered without oil filling!
Oil level sight glass (standard design)
Remove oil filling plug (637) and fill oil
into the connection opening (GF1).
Fill in oil up to the middle of the oil level
sight glass (642) (pic 7). Keep level ex-
actly. Overfilling leads to increased bear-
ing temperature and possibly oil leakage.
If oil level is too low this can cause short-
coming of lubrication.

ƒ Supplied
loose.
ƒ Unscrew the reservoir from the main body (right
threaded) and set aside.
ƒ Seal the main body into the bearing bracket (330),
through a PTFE sealing tape, at connection for
constant level oiler (638). Tighten until threaded
boss is in vertical position (picture 8).
ƒ Remove the oil filling plug (637) (upper side of
bearing bracket) and fill in oil through the connec-
tion opening (GF1), until the oil level reaches al-
