2 GENERAL
BAUER products are designed and manufactured carefully and subject to a system of continuous quality
control. MAGNUM slurry pumps fully meet the requirements of the agricultural practice. They are best suited
for delivering all kinds of slurries from thin liquid manure to viscous mixtures containing solids such as straw,
fibres or clots. A special chopper guarantees trouble-free performance without blockages. Short set-up times,
easy handling and maximum performance reliability are further advantages of this pump series. Pump drive is
electric by means of a three-phase submersible motor.
In order to be able to work efficiently with the maintenance-friendly long shaft pump it is helpful to operate it in
connection with a lift pole or transport trolley.
Depending on the respective type of application, you can use either the lift pole alone, or the lift pole with
coupling foot and rising main.
Although the pump is simple in design you should study this manual carefully and strictly observe all operating
and service instructions contained. On this condition your slurry pump will operate to your full satisfaction for
many years!
Make this manual available to all operators handling the equipment. Serial number and pump type are stamped
in on the nameplate. Please specify these data in your inquiries, correspondence, warranty matters and parts
orders. We warrant for this pump according to our General Terms of Sale.

Operating Manual for BAUER Long Shaft Pump 10
3 DESCRIPTION
The long shaft pump MAGNUM LE consists of a pump with a robust cutter and a top draw-in, the drive pipe
running in oil bath and a drive shaft with multiple bearings.
The riser pipe can be equipped with one or two stirring nozzles and is also available without a stirring nozzle
The stirring nozzle is mounted on a pivot together with the three-way cock and has the function to destroy the
floating layer and to homogenise the slurry. It can be vertically and horizontally turned via rods with a lever.
Changing from mixing to pumping is also done via a lever with rods with a rotary valve. This is also possible
during the operation.
The pump can be inserted into open and closed pits with a minimum opening of 0,6 m x 0,8 m.
The pump can be transported, inserted and operated by one person. For the transport mount a lift pole with two
wheels and a link it into the trailer hitch of the tractor with a detachable drawbar.
For the operation the drawbar is detached and the lift pole hung into the tractor hydraulic system.
A cable winch mounted to the lift pole helps to lift, lower and swivel the pump.
The pump is driven from the tractor via a PTO shaft, the bevel gear system, the drive shaft (LP) onto the
impeller or an electric motor flanged onto the drive shaft (LE) with a motor capacity of 11, 15 or 18,5.
The motors are equipped with a star-delta switch.
NOTE!
The motor cable should be connected to the switch only by a qualified technician.
Perform a check-up according to the wiring diagram !
ATTENTION! When connecting to the power supply, make sure that the connecting cable is
amply dimensioned and the motor’s direction of rotation is correct.
.
4 Assembly on lift pole
For transport reasons the pump and the lift pole are delivered separately. Both components therefor have to be
assembled before putting into operation for the first time.
Detach the guiding clamps from the pump support.

operate the cable winch and
reverse the tractor to swing it into
the pit.
When the pump is in its vertical
position, re-insert the stop pin into
the swivel device and lock.
Set the pump on the lift pole.
By lifting the locking lever of the
drive shaft, the height of the pump
can be adjusted.

Operating Manual for BAUER Long Shaft Pump 14
7 Setting up with the support for pit edge
Put the pump down to the ground of the pit, adjust it into a
vertical position and fix it with a clamp around the drive shaft to
the traverse. The girder and a if necessary, a working platform,
is fixed to the pit/container.
8 PUTTING INTO OPERATION
• When putting an electric pump (LE) into operation for the first time, check that the nominal voltage
coincides with the voltage given on the nameplate.
• Before connecting the motor, check the phase sequence for the direction of rotation of the motor.
• When connecting the motor, observe the regulations in force for electric resources.and the
instructions of the manufacturer of the drive (e.g. protectiv motor switch, main switch maybe
lockable).
Before putting into operation check the oil level at the control screw drive shaft and
bevel gear system (LP)! (quality and quantity see technical data)
9 STIRRING WITH STIRRING NOZZLE
From the top via the cutter the slurry gets into the pump and via the stirring nozzle it is pumped back into the pit.
If you have a slurry with a floating layer, lower the pump until the stirring nozzle dives into the floating layer. In
this position you reach the best stirring capacity.
If you have slurry with a strong bottom layer or sediment (e.g. pig slurry) the pump has to be lowered further.
The stirring procedure should be conducted until the slurry is completely homogenized.
WARNING!

Operating Manual for BAUER Long Shaft Pump 15
If tractor-driven
Connect with the PTO shaft. The overload protection has to be on
the tractor side.
Warning: Cutting to length, section pipe over-lapping, and
maintenance see separate instructions for PTO shaft. The bending
of the PTO shaft shall not be more than 30 ° .
The stirring device has three levers.
The function of the lever in the middle is to horizontally swivel the
pressure line including the stirring nozzle.
The lever to the left of it has the function to vertically swivel the
stirring nozzle.
The lever to the right of it has the function to switch the three-way
cock from mixing (lever up) to pumping (lever down) or both.
The position of the levers can be set with the clamping bolts.
Lower the pump until the stirring
nozzle dives into the floating layer.
By repeatedly swivelling the stirring
nozzle hence and forth, the time to
homogenize the pit content can be
reduced essentially.
10 Pumps
When the pit content is stirred evenly, the delivery can start. To do this, the delivery/pressure line has to be
connected.
Warning: The pump can only be lifted or lowered with the cable winch while the PTO shaft is at a standstill.
To pump, press the lever for the rotating valve down and fix with the tommy screw.
Warning: After coupling the tractor PTO shaft, only gradually increase the speed of rotation so that the pressure
line does not pressure hammer because of the sudden pressure.
While distributing the slurry, under normal conditions, it is only necessary to briefly mix every 3 hours.

Operating Manual for BAUER Long Shaft Pump 16
11 Service and Maintenance
It cannot be stressed often enough that maintenance essentially increases the lifetime of any equipment.
Clean the pump with all its accessories immediately after finishing the work. The
slurry has not dried yet and can therefore be rinsed off easily.
Inspect the cutting edges of the knives. Theiy are constructed in a
way that they can be used four times before they have to be
sharpened again.
If you take off a knife and then put it on again, take care that the
spacing between 2 cutting edges is between 0,1 mm to max. 0,3
mm.
This gap allows an optimal chopping up of the solid components in
the slurry. It can be adjusted with the knife supports on the spiral
housing.
To lubricate the bearings of the drive shaft, the drive pipe is filled
with oil type Shell HDS 1/20 (quantity see technical data) up to the
screw plug at the side of the pipe.
Change the oil for the first time after approx. 50 operating hours,
every further change only has to be conducted on the occasion of a
repair. An oil level check should be conducted every 200 operating
hours and can be done at the upper upper screw plug. Fill up, if
there is a minor oil loss. If there is a major oil loss, find out what the
reason is and repair the damage. Check particularly the sealing of
the lower shaft bearings.
The gear box is filled with 2 liter oil type Spirax 90 EP up to the
Kontrollschraube. Change the oild for the first time after 50
operating hours, every further change has to be conducted after
800 to 1000 operating hours.
All other bearings and sliding parts also at the lifting pole should be
lubricated on a regular basis.
WARNING!

Operating Manual for BAUER Long Shaft Pump 17
If possible, store the pump under a roof to protect it against the weather. In areas, where it gets frosty during the
winter, empty the pump housing by removing the plugs at the lowest part of the pump housing.
ATTENTION!
Important to observe:
Keep stones, iron and wooden pieces, binder twine, plastic bags etc. away from the
slurry pit.
Before doing work around the cutting knives, it is important to stop the tractor (LP)
and disconnect the PTO shaft and the power supply (LE).
Oil leaking during the standstill of the pump between the bearing body and the knife
hub shows that the sealing of the drive shaft at the lower bearing is worn-out and
must be replaced immediately. Otherwise there will be severe and costly damages
to the pump.
Observe the local laws and regulations when disposing of pumps and pump parts as a result of repair and
maintenance works or putting out of operation. This is especially valid for the treatment of medium remains in
the pump body.
