Screw pump for spraying or pumping conventional mortar and premixed plasters, fibre-reinforced and refractory mortars, grouting, fireproof materials, self-levelling screeds and for reinforcing injections at controlled pressure. Optional planetary mixer.
The mixture prepared in the mixer is poured directly into the hopper through a vibrating grid that filters out any big size stones. The material is sucked by the eccentric screw pump and pushed into the hose until it reaches the opposite end where the spray gun is located. With the help of the air supplied by the standard integrated compressor, the material is projected through the gun onto the application area. Different accessories can be connected to the hose for spraying the products or devices for controlled pressure injections, or the machine can be used simply “with an open hose” for the pouring of self-levelling or filling products. The exclusive IMER A1 inverter allows to set the pumping speed, adapting the machine to the different needs of use. Step 120 is also equipped with a diagnostic display, capable of immediately signaling any anomalies during use and the relative intervention methods. The IMER A1 inverter allows the machine to work with suitably sized generators.
