Sealant, adhesive and viscous fluids supply systems | Made in Italy
Feeding systems for viscous material applications.
Larius equips its delivery systems with compact, professional extrusion guns for the application of fluids with different viscosity and density. The delivery systems are also available in trolley version to aid in transport.

Pumping fluids different from those of the specified viscosity causes an imbalance.
The pumps and extrusion systems have been designed and rigorously tested to perform perfect suctioning of highly viscous products and to pump them with a steady stream, without sudden acceleration.

The Nova, Vega, Omega and Ghibli pneumatic pumps for extrusion work with a compressed air motor that
moves the piston vertically from top to bottom and viceversa. The product is suctioned by the lower pump and
carried to the outlet. The structure of the "pump unit" (suction valve, pump piston, material seal gaskets) allows
both the material and piston to be supplied in both the ascending and descending phases.
The flow rate of a pneumatic pump depends on the quantity of material that it releases during each cycle and on
the number of cycles that it completes (The cycle is the full stroke of the piston in both directions).
Pneumatic extrusion pumps are divorced: the pneumatic motor is separated from the pump and the fluid is not
in contact with the motor. In this type of transfer pump, the suction valve is not ball-shaped but that rather has a
small plate that allows the user to pump very viscous materials (up to 2 million cps)
Generally these pumps are mounted on pneumatic rams that allow for the product to be suctioned directly by the
drum and that allow for quick replacement of the drum itself.
A pressing disc, fixed to the base of the pump, compresses the material eliminating the phenomenon of cavitation,
ensures a constant flow of product and protects the materials that has not yet been pumped from contact with
dust, humidity, and from drying-out caused by contact with air.
