Capacity
The capacity of the mixer will always depend on the consistency of the medium, but especially on the design of the
tank.
Inspection
Regular inspection will ensure the mixer a long life at low costs. The oil must be changed every 4 months/2,500 hours
of operation, however, min. once a year. Under difficult operation conditions, more often than every 4 months.
Oil control
The oil is checked by removing the upper oil plug (pos. A). The oil has to be clean and the level has to reach the level
of the plug hole. Oil type: see spare parts list. If the oil is dirty, it must be changed.
A. Top oil plug
B. Lower oil plug
C. Inspection Screw
The oil is drained off by removing the plugs (pos. A and pos. B). If the
oil is dirty, the outer seal must be checked for wear and
contamination.
Oil is filled at oil plug (pos. A).
The inner seal must be checked in the following way:
Remove the inspection plug (pos. C) beneath the motor. A small
seepage of oil is normal. The oil quantity is checked by drainage (pos. C).
In case of abnormal seepage, it is necessary to check the inner seal.
If it is necessary to dry up the motor windings, contact a special workshop.
Equipment
The equipment should be checked for wear and corrosion. The winch is to be grease lubricated. Check brake and
lock. Retighten screws. If the screws are loose, remove them and lubricate with an adhesive substance (e.g. Loctite)
prior to reinstallation.
Disassembling/assembling the unit
A major repair should take place at a special workshop.
Below please find some general conditions regarding disassembling/assembling of Landia mixer type PODR-I.
The drawing attached to the spare parts list shows the construction of the unit. Not all parts can/should be dismantled,
e.g. do not press the rotor off the shaft.
When disassembling the unit, handle the mechanical seals with care as they are not shock resistant.
Prior to reinstallation, all sealing surfaces must be cleaned, all O-rings must be checked and changed, if necessary.
Adhesive substance (e.g. Loctite) must be applied on all bolt joints. All bolts are tightened with a tightening torque
acc. to the table below.
