2 Description
2.1 Intended application
The intended use of the P50 consists in the pumping of previously mixed, pumpable materials like bricklaying mortar, slot-
ted mortar, decorative renders, and llers with a max grain
size of 8 mm.
Using the P50 for any other purpose poses a danger to
the life and limb of the user or of damage to the machine
and other assets and may jeopardise the machine’s oper-
ating efciency.
2.2 Application and operating principles
The P50 is a universal pump for materials that can be mixed
in a machine.
The dry material is rst mixed in a separate continuous mixer
and emptied into the pump’s hopper. There, the material is
additionally mixed by a specially designed conveying screw
that transports it to the worm pump and from there to the
processing site.
Hoppers with a capacity of 90 l and 120 l are available for
this pump.
When the pump is tted with a 120 l hopper, an additional
agitator can be installed for the optimal mixing of viscous
materials.
The pump can be operated from various workplaces, either
directly at the pump’s switch cabinet (e.g. for starting up or
cleaning) or from a more distant workplace at the remote
control or spray gun.
392425 - 2011-09
Page 13
Description 13
The material supply can be regulated automatically with a wet
material probe.
The wet material probe monitors the level in the pump’s hopper
and regulates the upstream continuous mixer. It is connected
to the mixer’s switch cabinet. The continuous mixer is switched
OFF automatically when the max level is reached in the pump.
When the level falls, the probe switches the continuous mixer
back ON.
For the spraying process, the machine must be tted in addition with a compressor, air ttings, and a spray gun.
The compressor supplies the compressed air needed for the
spraying process. The machine is regulated by the spray gun
in conjunction with the pressure controller.
Depending on the conguration, the machine is tted with either
a 90 l or a 120 l hopper and a switch cabinet with or without
frequency inverter.

9 Maintenance
The machine must be inspected for safe operation by an
expert in accordance with the legal provisions, but no
less than once a year.
Before all troubleshooting, cleaning, and maintenance
work the machine must rst be switched OFF and disconnected from the mains power supply. Even when the
machine is switched OFF some parts are still conducting.
Only spare parts and accessories supplied by m-tec may
be used. If nonapproved spare parts and accessories are
used, m-tec will assume no liability for damage caused.
The applicable environmental conditions must be observed when oils, greases, and cleaning agents are
disposed of.
9.1 Regular maintenance
• At regular intervals, remove mortar residue on the convey-
ing and worm pump, pump end piece, and hopper.
• Use a grease gun to ll regularly the rubber gasket at the
hopper.
• Regularly examine the good condition of the hose and ca-
ble connectors, and in particular of the consumers.
• When a compressor is used, its lter must be cleaned at
regular intervals. When severely clogged, the lter must be
replaced.
392425 - 2011-09

Maintenance 47
9.2 Oil changes
Warranty claims can be acknowledged only when the
lubrication rules are observed.
There must be no rell of gear oil between oil changes.
This can cause overlling and in turn excess heating in
the gears.
Do not intermix different oil types! This can cause decomposition of the oils and in turn damage to the gears.
When delivered, the electric motor and gears are ready to operate and maintenance free for up to 8000 operating hours.
Afterwards the gears must be cleaned thoroughly with a suit-
able ushing oil and examined.
We recommend the low viscosity grease Esso S420
(1000 cm³) for relubrication.
When this lubricant type is unavailable, you may use the
lubricants listed below:
BP Energol SG-XP 220
Mobil Glygoyle 30
Shell Tivela Oel WB
