Mini Pump 4
1 Technical description
The Mini forms part of UTIFORM’s long trajectory in manufacturing mixing pumps for
bagged material. These machines mix the material to a homogenous consistency while also
allowing the hydro-mechanical transport of the material by means of a perpetual screw pump.
The Mini pump is loaded with bagged material. Compared to the traditional systems, this pump
has a more functional structure, while requiring less maintenance, and is particularly suitable for
mixing and conveying prepared mortars and dry premixed material such as adhesive for tiles,
structured mortars and plaster as well as mortar for plastering. The Mini is ideal for those
situations where an immediate availability of material is more important than the pumping
capacity.
The machine itself comprises a dry material deposit which has the mixing tube
connected to it at the bottom. At the top of the dry material deposit there is a motor reductor with
its corresponding cover which activates the mixing beater by means of a stop shaft. The
transversal bar of this then activates the perpetual screw of the mixing pump eccentric situated at
the bottom of the mixing tube.
The mounted perpetual screw pump comprises an auto adjustable and fixed (stator)
cover for the perpetual screw, and a perpetual screw for the eccentric (rotor) made of a material
highly resistant to wear and tear. With this system the nuisance of having to adjust and retighten
the stator screw is avoided.
To avoid damage during transport the machine’s chassis is installed with both the
electronic control panel and other control devices as well as the valves to regulate the exact
amount of water in the mix.
2 Operating mode
The operating mode is similar to that of a mixing pump. The dry material deposit is
loaded with the bagged material. The dry material falls into the dry area of the mixing tube and
the motor reductor makes the mixing beater turn. The mixing beater has spiral screw threads
which bring the dry material to the wet area of the mixing beater. A small joint provides a
continuous jet of water which can be regulated with precision. The dry material and the water are
mixed together in the shortest possible time and are transformed into a mass which can be
pumped and is ready to use.
The single screw pump installed at the bottom of the deposit transports the mixture
through the flexible pipe with a pumping capacity of up to 20 l/min, and brings it to the
projecting lance. The pump can be activated or deactivated by means of a remote pneumatic
control installed in the projecting spout. The pressure control valve in the water measuring
device makes the machine stop if the water pressure is insufficient. To enable ease of transport
the machine has two rubber-encased wheels that turn and two fixed ones, which makes it easier
to manoeuvre on a building site.
