Mini Pump 11
- If it rotates in the wrong direction, the phases on the lower part of the electricity input
plug must be rotated.
WARNING!
If the plug is changed or a main cable extension cable is not used, check
the rotation direction again.
5.7 Loading of air into the water regulator
Disconnect the water hose from the mixing tube and leave it in the bucket. Press the
electrovalve release button until no bubbles appear in the flow metre.
5.8 Adjustment of the water regulator
While the water valves are being loaded with air, regulate the desired amount of water by
pressing the electrovalve release button. Open the water control valve until the buoy reaches
approximately 400 l/h.
Note: The amount of water actually required by the product that is being mixed is
regulated later by the machine during operation until the desired product consistency is
obtained.
5.9 Pressure test of the perpetual screw pump (stator- sleeve)
The Mini pump is equipped with a maintenance-free pumping element (according to
customer’s request); its pumping pressure is optimally adjusted to the conditions at the work site
(according to both material consistency and composition and hose length and diameter).
Normally, the pumping elements not requiring maintenance are used until they reach their limit
of wear, i.e. until the supply flow is reduced substantially or the consistency of the material
ranges between thick and fluid. In these cases, the pump elements must be replaced.
If the wear of the maintenance-free set of pumps has to be controlled or if retensionable
sets of pumps are used, pump pressure is calculated as follows:
WARNING! The water hose is connected to the upper connection of the mixing tube,
the pump motor is lowered and the beater is removed from the mixing chamber. Activate
the electrovalve release button and let water enter the mixing chamber until it covers the
top of the perpetual screw (rotor).
In order to ensure that the water level in the mixing chamber does not continue to rise
while the pressure is being adjusted, disconnect the water hose from the mixing tube.
The process described below would be performed in the case with the option of the
pressure regulator:
After placing the mixer back in the tube and repositioning the head motor fixed with the
safety valve, connect the hydraulic pressure regulator to the sleeve outlet with the release valve
open. After briefly starting the head motor (approximately 1 or 2 seconds), the air is eliminated
from the pressure regulator. The release valve is then closed and the head motor is reactivated for
a few seconds; at the same time, monitor the oscillation of the pressure valve indicator needle.
The upper oscillation value of the pressure valve corresponds to the regulated pressure of
the pump!
