Installation and Starting-up
Put the solid materials pump in a horizontal possition.
** Network cable and limiters
Make sure that the main switch is disconnected. Then, extend the network cable up to 5x4 mm2
(from the engine power of 7,5Kw, a network cable of 5x4 mm
2
is needed). The pumps for solid
materials have been factory designed for a three-phase current of
400 V /50 Hz.
The building site electric supplier needs to be equipped with a switch against defective current
as under the established regulations. The jack box shall have the following limiters depending on the
pumping engine power:
from 2,2 Kw to 4,0 Kw =
16 A
from 5,5 Kw to 7,5 Kw =
25 A
from 9,2 Kw to 15,0 Kw=
35 A
** Checking the turn direction
Fill in the mortar hose until the worm headstock is completely covered. Start the main switch of
the circuit board. Connecting shortly the operation button, check the pump engine turn direction. The
engine shall turn in the arrow direction (over the engine fan) (to the left). If the direction of the turn is
incorrect, turn the reversal switch on the circuit board to select abother turn direction.
ATTENTION!
The pump shall never work dry. A dry operation and a wrong turn direction cause
damages beyond repair to the stator.
** Worm pump pressure
ATTENTION!
Too small cross sections in the mortar hose and to high transport pressures on them
cause a major wear in the pump elements or stator.
**Laying of the mortar hose
Only original UTIFORM hoses will be used, high pressure resistants, with factory-assembled
couplings. Depending on their lenghth and section, these hoses are supplied under our reference
numbers 38120 up to 38130. These hoses adapt theirselves to the recommendations and prescriptions
related to mortar transporting machines.
The mortar machine is connected either to the pump vent or to the mortar pressure control
device, and is to be laid by the shortest distance and without any folds up to the the building place
where the material will finnally be applied.
